XGC-1 Xtreme Greenhouse Controller

OVERVIEW

The XGC-1 Xtreme greenhouse controller from C.A.P. controls all of the main devices that

are used in today’s modern hydroponic garden. The built-in Fuzzy Logic



controls your

CO2level with unmatched accuracy.

WORD TO THE WISE...

Before attempting to operate the XGC, you should at least take the time to loo

at the Example Connection diagram on page 2 and read the “Start-up

rocedure on page 3 of this manual. To get the most out of the XGC-1,

amiliarize yourself with this manual. It contains many useful hints, examples

and a troubleshooting guide.

IMPORTANT STUFF TO REMEMBER

The XGC is designed to operate from a 120vac, 15-amp power source. It can safely control up to 15-amps of equipment

including up to 1000 watts of HID lights. If required, additional lights and larger equipment can be connected to the XGC-1 by

using our HPR, MLCs or UPM “Universal Power Modules”.

In addition to lights, the XGC also maintains the temperature and humidity by controlling your exhaust fan(s). CO2levels can

be controlled with the built-in timers, which are coordinated with your exhaust fans and function only when the lights are ON.

PROTECTION & SAFETY

The XGC is overload protected a main 15-amp fuse. Do not exceed the maximum rating of the XGC-1.

IMPORTANT: Replace blown fuses with fuses of the same rating ONLY!

Note: A surge suppressor / power strip is always recommended when operating electrical equipment such as the XGC.

WARRANTY

The XGC is protected by our 3-year limited warranty. All components are warranted by R & M Supply against defects in

workmanship and materials under normal use for 3-years from the date of purchase. The XGC is 100% maintenance-free and

does not require service.

INSTALLATION / START-UP

There are a few requirements for a successful installation and start-up.

1) The XGC must be mounted in a vertical position. Mounting feet are included to allow you to secure the unit to a wall.

2) The XGC requires “free air movement” to maintain temperature and humidity accuracy. The top and bottom of the

enclosure has ventilation slots to provide airflow through the unit however, we greatly recommended using an oscillating

fan in the growing area to provide fresh air for the internal humidity sensor and provide adequate ventilation for the

internal electrical components.

3) A dedicated 120 VAC, 15-amp power supply is recommended. A ground wire (3-wire outlet) must be used.

Do not use 2-wire adapters or cords to operate the XGC.

4) The XGC must be protected from water. Do not mount the unit where it can be exposed directly to water.

5) Read the rest of the manual!!! It has been designed to take you through step-by-step to make start-up a breeze.

START-UP PROCEDURE

OVERVIEW

“There is no substitute for reading and understanding the operating manual however... You can use the

instructions on this page for a trouble -free start-up”.

HOW TO START-UP THE XGC

1) Locate a suitable source for power. A 3-wire, grounded, 15-amp dedicated circuit is recommended.

2) Secure the enclosure to a wall using the enclosed mounting “feet”. The XGC requires a vertical orientation for proper

internal ventilation. If proper ventilation is not provided, the thermostat may not be able to properly control the

temperature & humidity of the growing area.

3) Plug the XGC into the power source. Do not connect your lights until you have set the “ON and “OFF” times on the

24-hour timeclock.

4) You may want to change the CO2set point on the “Fuzzy Logic”controller. Normally 1250 to 1500 PPM is

recommended for most applications. Once you set the PPM level, the built-in CO2sensor and “Fuzzy Logic”module

work together to actually dial-in the perfect parameters for YOUR area automatically. Refer to Changing the setpoint (SV)

5) Now set the thermostat and de-humistat to the approximate settings you would like to use. A small, inexpensive

combination thermometer and hygrometer works just fine to “dial in” the exact settings. Just compare the reading on the

thermometer to what the XGC is set at and adjust as required.

6) You can now select the Hydro mode you would like to use. Choose between operating the Hydro outlet during the

“Daytime” only or, 24-hours a day. Move the Hydro mode switch to the appropriate position. Moving the switch to the

center “OFF” position momentarily will reset the timer.

7) There are 2 timers on the XGC, which are used to control your hydroponics pumps. To fully understand the timers that

control the XGC, refer to the Timers section of this manual. Set the Hydro “ON” and “OFF” timers to your desired

settings before continuing. (Refer to Timers)

8) The 24-hour timeclock can now be set. Push in the trip levers on the front face of the timer dial for the time you want your

lights to be “ON”. Rotate the dial to the current time to set the timer.

9) Now you can plug the equipment you will be using into the appropriate receptacles. Remember that the XGC can handle a

combined load up to 15-amps. A single 1000-watt HID ballast needs over 9-amps alone. Select and size your pumps and

fans appropriately or use our UPM-1 or MLCs to increase power capacity.

*Note: We highly suggest NOT plugging in your HID ballast just yet.

10) When the “day” cycle begins, the “Lights” indicator will light up to confirm power is going to the (2) light receptacles. If

you have selected the “Daytime” setting on the Hydro mode, the “Hydro Pumps” indicator will also light up to indicate

your pump is powered for the amount of time you selected

11) You can manually override the timeclock to switch from “night” to “day” or back to Night by rotating the outer dial of the

timeclock slowly clockwise. At night, the Lights and CO2are disabled while the thermostat and humistat continue to

control the temperature and humidity.

* NOTE: The Hydro outlet will also be disabled if the “Daytime” mode is selected on the Hydro mode switch.

12) When all settings have been confirmed, the HID lights or UPMs can be plugged into the “Lights” receptacles. If more than

1000 watts are to be controlled, use our Universal Power Modules or the MLCs.

* IMPORTANT: Do not plug in more than 1000 watts worth of lighting into the XGC receptacles.

13) Monitor the equipment connected to the XGC to ensure proper operation. Small adjustments are likely to be made until

you find the right combination of controls. Once you are happy with the settings sit back and enjoy the show!

For more details concerning any of the XGC functions, refer to the appropriate section of this manual.

“CONTROLS”

OVERVIEW

“The XGC-1 controls your lights, hydroponic pumps, exhaust fan or A/C, de-humidifier, heater and CO2level with

“Part-Per-Million” accuracy… automatically! No more guesswork!

24 HOUR TIMECLOCK

The timeclock selected to run the XGC performs all of the day to night transitions required for crops requiring controlled

photoperiods. It can directly control up to 1000 watts of HID lights.

To set the current time on the timeclock, turn the dial clockwise until the current time on the outer dial lines up with the arrow

on the inner dial. To set the timeclock on and off times, carefully push in each of the orange trip levers at the times you want

the lights to be on.

*NOTE: If power is interrupted, the timeclock will have to be reset.

TEMPERATURE CONTROLLER

The XGC utilizes a remote-bulb thermostat with a 30” lead to control ventilation and cooling functions. This allows you to

place the temperature sensor up to 30” away from the XGC. The thermostat can be set to control temperature from 50 – 115’F.

The thermostat is coordinated with the CO2control system and the exhaust receptacles to maintain a constant temperature.

When the temperature rises above the set point selected on the thermostat, the CO2system is disabled and the Exhaust

receptacles are enabled. When the temperature level drops below the set point, the CO2system is re-activated.

IMPORTANT: To achieve the greatest accuracy, provide the XGC with plenty of “fresh air”. The enclosure is designed to

allow air to pass over the humidity sensor.

HUMIDITY CONTROLLER

The XGC utilizes a de-humistat to control ventilation and humidity levels. The de-humistat can control humidity levels from

20% - 80%.

The de-humistat is coordinated with the CO2control system and the exhaust receptacles to maintain a constant humidity.

When the humidity rises above the set point selected on the de-humistat, the CO2system is disabled and the Exhaust

receptacles are enabled. When the humidity level drops below the set point, the CO2system is re-activated.

HYDRO MODE SELECT SWITCH

The Hydro mode select switch is used to select whether the hydro outlet will cycle 24-hours or only during the day. The mode

selector switch also doubles as a Hydro bypass switch. Each time the switch position is changed to the center “OFF” position,

the hydro timers will reset and initiate a new cycle. This comes in handy during set-up of the hydro pumps and timer settings.

NOTE: *Leaving the mode select switch in the center position disables the hydro function.

NIGHT ONLY DEVICE

An additional outlet is provided which is powered only at “night” when the lights are turned OFF. This works great for

heaters, fans, dehumidifiers or any other device that needs to run only at night.

WHAT IS “FUZZY LOGIC”CO2 Control?

What set’s the XGC-1 apart from the competition? Fuzzy logic… What is "fuzzy logic"? Fuzzy Logic can be compared to a

good driver. As a good driver approaches a red light, he or she applies the brakes to gradually slow down BEFORE getting to

the intersection. Fuzzy Logic uses the same idea to bring the CO2 level up to the desired setting without going over the set

point. With Fuzzy Logic, relatively safe compressed CO2 can replace LP / gas CO2 generators economically.

The XGC combines an extremely accurate infrared CO2sensor with a state-of –the-art Fuzzy Logic module to give you the

most precise method of controlling supplemental CO2. SIMPLY SET IT… AND FORGET IT!

Page 4

TIMERS

OVERVIEW

The XGC-1 uses 2 timers to control the hydroponic pump functions. It also has a 24-hour time-clock which

controls your daytime and nightime functions.

ADJUSTABLE RECYCLING TIMERS

The two Adjustable Recycling Timers (ART) provide an adjustable “ON” / “OFF” cycle for various devices. The 2-adjustable

recycling timers onboard the XGC are set using the dials on the front face of the enclosure. The timer name and range of each

timer is printed around the timer dials. Because the dials of the XGC are small to conserve space, the settings may have to be

adjusted to an actual time setting. If necessary, use a watch or stopwatch to confirm the settings are correct. Once the timers are

set, they are repeatable to +/- .5%.

The timers are designed to finish the cycle they are presently timing which means adjustments made to the timers during a

cycle will not affect the present cycle.

RESETTING HYDRO TIMERS: The Hydro timers can be reset by switching the Hydro mode select switch to the center

“OFF” position momentarily. Switching back to your desired mode starts the timing cycle.

HYDROPONIC PUMP TIMERS

The Hydroponic outlet can be configured to cycle one of two ways… 24-hours a day or, during the “daytime” only. Simply

moving the Hydro Mode selector switch to either the “24-Hour” or the “Daytime” position enables the desired mode. When

used in the Daytime” mode, the Hydro outlet will only cycle while the lights are on. The “24-hour” mode works great for NFT

or aeroponic systems that require moisture during the day and night. The mode selector switch also doubles as a Hydro bypass

switch. Each time the switch position is changed, the hydro timers will reset and initiate a new cycle. This comes in handy

during set-up of the hydro pumps and timer settings.

There are two timers that control the hydroponics receptacle, Hydro “ON” and Hydro “OFF”. The XGC-1’s Hydro “ON” time

can be set from 30 seconds to 20 minutes; the Hydro “OFF” time can be set from 12 to 480 minutes. Set the timers by moving

the dial to the appropriate position.

24 HOUR, TIMECLOCK

The timeclock selected to run the XGC performs all of the day to night transitions required for crops requiring controlled

photoperiods. It can directly control up to 1000 watts of HID lights.

To set the current time on the timeclock, turn the dial clockwise until the current time on the outer dial lines up with the arrow

on the inner dial. To set the timeclock on and off times, carefully push in each of the orange trip levers at the times you want

the lights to be on.

*NOTE: If power is interrupted, the timeclock may have to be reset.

CO2CONTROL

OVERVIEW

Most people who have used the XGC-1, rate it the best combination controller available today.

The fact that the built-in “Fuzzy Logic”



2control system has redefined what true Part-Per-Million CO2

control is really about, may have something to do with it…

“SUPPLEMENTAL CO2”

Let's talk about ... Carbon Dioxide. CO2is present in relatively low quantities, (300-600 PPM) in your normal, generic,

everyday air. But plant growth can be increased and accelerated if the level of CO2is increased to, let’s say... 1000 -1500 PPM.

For this reason, the XGC can control CO2distribution for those people who prefer to use supplemental CO2.

There are some inherent dangers associated with using CO2. Here are some of the rules to remember when using CO2:

A) Cylinders (bottles) of compressed CO2should never be stored inside the growing area or anywhere else where the

temperature may rise above 100º F.

B) The growing area should not be occupied while CO2is in operation.

C) Do not enter the growing area until the CO2has been exhausted.

D) CO2is heavier than air and will accumulate towards the ground.

E) In high enough concentrations CO2can kill!!! The OSHA maximum “Personal Exposure Level” is 5000 PPM.

*Note: The XGC CO2control system can be used for both compressed CO2cylinders, and generators. The CO2receptacle is

120vac. Compressed CO2cylinders require an approved regulator / flow gage and a valve.

If optimum CO2“mileage” is desired, a self-contained air conditioner or other “Closed loop” cooling method is highly

recommended. A closed loop system will regulate temperatures within the zone allowing you to extend the CO2maximum

cycle time thus reducing CO2use dramatically.

Another method of reducing heat build up includes utilizing “Ventilated light hoods”. Just be sure to make the ventilation

system of the hood as airtight as possible so that your precious CO2is not being drawn out of the area by the ventilated hood

exhaust fan.

If sufficient CO2is provided and the proper level of nutrients and light is available, a 35% increase in growth rate is possible.

However if you suspect the higher temperatures are adversely affecting the plants, a shorter CO2cycle may produce better

results. Remember that a shorter CO2cycle duration translates to increased CO2usage.

FUZZY LOGICCO2 CONTROL

Fuzzy Logic is a form of Artificial Intelligence (AI). It is as though a trained operator is there to monitor the level and release

more CO2only when required. It can also "learn" how to maintain the set point when it is first started by pressing a couple of

buttons. It then calculates how to best maintain the CO2level for any size space… automatically!

AUTO-TUNING CO2

Every growing area has variables such as area size, fan types, ambient temperature, unique airflow characteristics, CO2

delivery system and flow-rate. Ordinary “part-per-million” controllers do not take most of these variables into consideration

thus they are not very good at keeping the CO2at a constant level. A standard set of “parameters” which define how the Fuzzy

Logic’s AI (Artificial Intelligence) is pre-programmed into the XGC-1. For MOST applications, the standard set will work

fine. In fact, most people report the XGC-1 maintains their desired setpoint +/- 15-25 PPM.

If after a few days of operating the XGC-1 you are not satisfied with the performance, you can try to allow the unit to “re-

teach” itself the base parameters FOR YOUR SPECIFIC AREA. And that is exactly what the “Auto-Tuning” function does.

When the “Auto-Tuning” function is used, the XGC-1 automatically measures your systems performance and calculates the

best method to control CO2within the area. It then uses this information in conjunction with a simple form of Artificial

Intelligence called Fuzzy-logic to give you truly exceptional efficiency. Auto-tuning is only required when using compressed

CO2 and Fuzzy-logic control mode.

There are ONLY four reasons to perform “Auto-Tuning” and most people will not see any improvement over the factory

setpoints.

1) Unsatisfactory performance after operating the unit for a few days.

2) Changing the set point (SV) more than 500 PPM.

3) Major (and some minor) changes in the CO2delivery system, area configuration, fan changes, ECT.

4) Abnormal or inconsistent results from previous Auto-Tunings.

*Note: NEVER perform an Auto-tune when using a CO2 generator.

CO2CONTROL (Continued)

HOW TO PERFORM “AUTO-TUNING”

The Auto-Tuning function takes from 1 ½ to 2 ½ hours to complete. DON’T WORRY. It is completely automatic once the test

is started. However, before performing an Auto-Tuning, you MUST prepare the area for the procedure. This may take at the

most 15 minutes.

1) During the Auto-Tuning, the area must be operating normally. Circulating fans must remain operating.

2) Exhaust and/or cooling fans which bring fresh air into the area must be disabled. If heat or humidity build-up is a problem

during the 2-hours required, reduce the lighting or other heat loads temporarily until the test is completed.

3) Set the CO2flow-gage to the setting most likely to be correct for your area. If no estimate is known, set it near the middle

of the range and increase it if the first Auto-Tuning does not provide consistent control.

4) Turn the thermostat & humistat responsible for running the exhaust fans all the way to the maximum setting until the

Auto-tune is complete.

5) Close the CO2tank valve. Connect the CO2valve or generator to the XGC-1. There should be no CO2flowing out of the

tank until the test is started.

6) Set the SV (desired CO2level) to the desired level. (See Changing Set-Point)

7) Press [SEL] for 1 second. (RUN will be displayed)

8) Press the [Down] button one time. (AT will be displayed)

9) Press the [SEL] button once. (0 is displayed)

10) Press the [UP or DOWN] button to bring up 1. (1is displayed)

11) Press the [SEL] button once. The decimal point will begin to flash until the Auto-Tuning procedure is completed. The CO2

outlet will be energized.

12) Quickly open the CO2tank valve and verify CO2is flowing out of the flow-gage / regulator.

13) Get out of the area and do not disturb the area for a minimum of 2 hours. After two hours, enter the area and confirm the

decimal point has stopped flashing, which indicates the test is complete.

14) Reconnect the Exhaust fans, CO2Disable cable and return the area to normal operation while monitoring the level of CO2.

Do not continue to stand next to the XGC-1 while monitoring. Just keep an eye on the display and record the level every

30 minutes or so. Also try to observe the unit reacting to and recovering from the Exhaust fans operating. The level should

drop down to 800 or less and then recover quickly without overshooting the setpoint more than 150 PPM.

15) If after operating a day or two you are not getting good consistent control, (+/- 100 PPM from set point) it may be a good

idea to perform a second Auto-Tuning.

*NOTE: If your CO2tank runs out for a period of time, the control may take a few hours to re-stabilize, this is normal.

CHANGING THE SETPOINT (SV)

The XGC-1 has an adjustable set point. The set point is the minimum CO2level in Parts-Per-Million you want to maintain. The

face of the Fuzzy Logic controller has 5 led indicators on the front. The one marked (SV) is illuminated when viewing and / or

changing the set point.

1) Press (SEL) momentarily. The SV indicator will light up and the current set point is displayed.

(The XGC-1 is factory set @ 1500 PPM)

2) Use the (UP / DOWN) buttons to change the set point to your desired level. Normally between 1250 –2000 PPM.

3) Press the (SEL) button momentarily to accept the change.

CHANGING CONTROL MODES

People operating compressed CO2 systems will definitely benefit from the XGC-1’s “Fuzzy Logic”. But some people who are

using LP / Natural gas generators may want to extend the life of their generator by changing the XGC-1’s control mode to ON /

OFF. When operating in ON / OFF mode, the rapid pulsing of the control solenoid is eliminated. The XGC-1 will still control

the CO2generator with extreme accuracy. A preset hysteresis (dead-band) of 50PPM still allows the XGC-1 to control the CO2

to an average level of +/- 200 PPM. For comparison’s sake, the average accuracy of the Fuzzy Logic control mode is around

+/-25PPM. Follow the procedures listed below to easily change the control modes on the XGC-1.

2) Press the (SEL) button momentarily. (The current proportional band setting will be displayed = 0.0)

3) Using the (Down) pushbutton, change the display to read (5.0)

4) Momentarily press the (SEL) button to accept the change.

5) Allow the unit to re-start by not touching any of the buttons for approximately 30 seconds.

* Note: There are several other “hidden” internal parameters that are normally locked-out from the user. These setting

are critical in order for the unit to function properly. DO NOT change any of these settings! If you mistakenly access these

“weird” numbers reset the unit. To reset the unit, unplug the main power cord for 20 seconds and re-connect.

CALIBRATION

The XGC-1 is factory calibrated. The sensor onboard the XGC-1 is capable of remaining in calibration for a minimum of three

years. Extreme shock during shipping and other factors may affect the calibration. To check the calibration, follow the

procedure below.

Supplying the unit with outside air can quickly verify the calibration. The reading outdoors should be around 250-550PPM. If

the XGC-1 calibration is incorrect, the unit can be returned to the manufacturer. Please note:

• The XGC-1 CO2sensor has built-in temperature compensation that automatically corrects the reading depending

on the ambient temperature. However, extreme temperatures of below 20°F or above 120°F may affect the reading.

• Checking calibration in urban areas usually results in higher ambient CO2readings due to car exhaust and human

activity.

To check calibration:

1) Bring the unit outside so that it will receive fresh air. Do not locate the unit in direct sunlight.

2) Plug the power supply and power cord into 120vac.

3) Move away from the controller to allow the reading to stabilize for approximately 20 minutes.

4) Check the CO2level.

*Important: Do not breathe while checking the calibration the unit. As you exhale, large concentrations of

CO2are expelled from your lungs. This higher level of CO2will affect the calibration of the unit. Try to hold

your breath!

5) If the level is between 250 and 550 the unit is performing fine. If it is outside that range, allow the unit to stabilize longer.

6) If the calibration is still off, the unit can be returned to the factory for re-certification.

OPTIONS

OVERVIEW

The XGC-1 can be upgraded and expanded by using our expansion devices including the UPM-1, and the MLC-4.

The Universal Power Modules and Master Lighting Controllers allow you to run multiple pumps, fans and lights by

controlling remote relays.

UNIVERSAL POWER MODULE (UPM-1)

The UPM-1 Universal Power Module is a unique device that can allow the user to run

additional HID lights or control multiple fans / air conditioners etc.

The UPM-1’s “plug-box” was designed to be plugged into a standard household outlet.

The 16-foot long “trigger cable” coming from the UPM-1 is then connected to your

control device such as a time clock or thermostat. When the control device turns ON, the

relay inside the UPM-1 box applies power to the twin outlets on the front of the UPM-1

turning ON whatever is plugged into it. This allows you to run additional lights etc.

from a different circuit with one common control device.

The UPM-1 is rated at 15-amps @ 120 volts.

HIGH POWER RELAY (HPR-1)

The HPR-1 is a hard-wired, 30-amp capacity, 120/240-volt version of the UPM-1. The

HPR-1 is perfect for controlling higher loads such as large air-conditioners or multiple

HID ballasts. The user can supply either 120 or 240-volt power to the “input” side of the

HPR-1. The air-conditioner or ballasts to be controlled are then wired into the “output”

side of the relay. When the trigger cable connected to your control device is activated,

the relay applies power to the equipment connected to the HPR-1.

The HPR-1 is rated at 30-amps 120/240 volt.

MASTER LIGHTING CONTROLLER (MLCs)

The MLC-4 and MLC-4a Master Lighting Controllers are the best devices for

controlling up to (4) HID lights from one time clock or controller. Like the HPR-1,

power must be brought into the “input” side of the control relay. The MLC-4 features (4)

standard 240v outlets, which your ballasts are plugged into. The MLC-4a is designed for

120 volt ballasts however it can also be used to run ballasts wired for 240-volt operation,

which have 120-volt power cords. The MLC-8 Master Lighting Controller is the best

device for controlling up to (8) HID lights from one time clock or controller. Power is

brought into the MLC-8 by hardwiring up to a 40-amp circuit. The MLC-8 features (8)

standard 240v outlets, which your ballasts are plugged into.

The MLCs both feature a 120-volt trigger cable to plug into a standard 24-hour timer or

controller. The MLC-4 & MLC-4a are rated 30-amps @120/240 volt. The MLC-8 is

rated at 40-amps @ 240 volt.

HID LIGHTING CONTROLLER (HLC-2)

The HLC-2 HID lighting controller was primarily designed to protect your expensive

HID lights from HOT-STARTS.

A “Hot-Start” occurs whenever your lights are turned off… and then back on before the

lamps are allowed to cool off. Hot-starts caused by power outages reduces your lamp’s

life and intensity. It can be plugged into either of the “Lights” outlets.

When the HLC-2 is connected to your lights, it will sense a power interruption, and start

a 15-minute time-delay to keep the lights from trying to re-fire while the cool down. The

HLC-2 can also be used to delay other devices from starting.

The HLC-1 is rated for 15-amps @ 120volts.

TROUBLESHOOTING

If you are having problems with this unit, refer to these troubleshooting hints. Also, refer to the connection diagram

to ensure your devices are connected properly.

Problem Suggested Action

♦ I have no lights and no

function at all.

♦ Check the fuse and main power. Replace the fuse if required with the correct rated fuse.

♦ Check the equipment connected to the XGC for problems and/or short circuits.

♦ The fuse continues to

blow.

♦ If the fuse blows repeatedly, verify the devices connected to the unit are working properly and that they

are not too large for the XGC-1 to safely control.

♦ You may need to consider using expansion modules, (UPM / HPR / MLC) to decrease the amperage

(load) on the XGC fuse.

♦ The fans are running so

often, the CO2is hardly

ever ON.

♦ You may have too much heat building up in your area or too small of an exhaust fan. Reduce the heat

sources or increase your fan size.

♦ You may also consider using a “closed-loop” air conditioner to keep the temperature and humidity

below the set points so that CO2is allowed to run for longer amounts of time.

♦ My CO2consumption

seems to be quite high.

♦ Make sure your area is sealed. You may want to install a motorized damper to seal your exhaust fans

when they are “OFF”.

♦ The Hydro pumps are

not cycling properly.

♦ The Hydro pump outlets can be operated 24-hours a day or only when the “Lights” are “ON”. The

“Hydro” selector switch also has a center “OFF” position, which can be used to “reset” the timing

function. Make sure the switch is not turned “OFF”.

♦ The CO2outlet is pulsing

ON and OFF too often.

♦ If you are running a CO2generator, you may want to change to ON / OFF control.

♦ If running compressed CO2 you may want to try running an Auto tune.

♦ After my compressed

bottle or LP tank was

replaced, the level

fluctuates.

♦ If your CO2tank runs out for a period of time, the controller may take anywhere from a few hours to a

couple of days to re-stabilize, this is normal. When the tank ran out, the PPM-2a tried to compensate by

changing its internal settings.

♦ My CO2outlet never

comes on.

♦ Make sure the CO2disable function is not ON.

♦ If the actual CO2level is above the set point (SV) the outlet will not turn on. Allow the level to drop or

raise the (SV).

MAKING CONNECTIONS

All of the main functions controlled by the XGC are accessed using (8) standard 120 VAC, 15-amp receptacles mounted on

the sides of the enclosure. This allows you to simply “plug in” any standard device without hardwiring or hassles. Printed

labels on the front face of the enclosure identify the receptacles.

We highly recommend using only 3-wire devices with a ground. Suitably double-insulated devices are acceptable. Keep in

mind that the combined amperage draw on all of the devices connected to the XGC-1 must be less than 15-amps @ 120 VAC.
