Introduction
EVAPCO Controller
Congratulations on the purchase of your eco-Air unit with the EVAPCO Controller. The EVAPCO Controller will ensure that your
eco-Air unit is operating in the most efficient manner possible while using minimal resources. Along with proper eco-Air unit
maintenance, the EVAPCO Controller will ensure that your eco-Air unit provide years of service at peak efficiency.
The EVAPCO Controller serves as a single connection point for the eco-Air unit and contains all of the protection and logic devices
required to run the eco-Air unit in the most efficient manner possible.
n order to reduce downtime, Evapco recommends keeping a stock of spare fuses. Consult the wiring diagram for the quantity,
type, and fuse size required. Contact your local EVAPCO representative for replacement or spare parts.
This bulletin includes a description of the screens and parameters that are available through the display located on the front of the
EVAPCO Controller. Also included in this bulletin are the functions of the EVAPCO Controller. Please note that the screens
displayed on your EVAPCO Controller display may vary slightly from the images shown in this document.
Become familiar with the EVAPCO Controller by thoroughly reading and understanding the content of this bulletin. A detailed wiring
diagram can be found in the data pocket inside of the EVAPCO Controller.
f you should require any additional information about the operation or maintenance of this equipment, contact your local EVAPCO
representative. You may also visit www.evapco.com for more information.
In tallation and Wiring
Safety
Qualified personnel should use proper care, procedures, and tools when operating, maintaining, or repairing this equipment or any
other connected equipment in order to prevent personal injury and/or property damage. The warnings listed below are to be used
as guidelines only.
Warning: EVAPCO eco-Air units should never be operated without fan screens and access doors properly secured and
in place.
Warning: Avoid working on electrical circuits while they are live. Proper lock-out/tag-out and all applicable safety
practices must be followed prior to servicing any equipment.
Warning: Before opening the panel door, allow sufficient time for VFD’s to discharge after removing power. VFD’s contain
capacitive circuits which maintain a charge even after power is removed.
Warning: The three position selector switch is not intended to replace or act as a disconnect to disable the EVAPCO
eco-Air unit and/or de-energize the EVAPCO Controller. Be sure to follow lock-out/tag-out and all applicable
electrical safety practices before servicing any equipment.
Warning: Do not attempt to service or enter the eco-Air unit even if the unit status is indicated as being off. Unless power is
completely removed from the eco-Air unit, it may be possible for the eco-Air unit to start at any time without notice.
Be sure to follow lock-out/tag-out and all applicable electrical safety practices before servicing any equipment.

Controller User Manual
The following safety issues need to be addressed by those responsible for the installation, maintenance, and repair of the EVAPCO
Controller:
•Access to the control panel (including the disconnect switch(es)).
• Sizing and protection of electrical circuits feeding the control panel(s) and branch circuits feeding the controlled equipment.
• Proper grounding of electrical circuits.
• Qualification of persons who will install, maintain, and service the electrical equipment.
Panel In tallation Con ideration
When the EVAPCO Controller does not ship factory mounted on the eco-Air unit, the EVAPCO Controller should be placed in close
proximity to the eco-Air unit to reduce the wire lengths required. f the EVAPCO Controller is within sight of or mounted on the eco-
Air unit, the EVAPCO Controller may be used as the main electrical disconnect for the eco-Air unit. Otherwise, separate electrical
disconnects may be required. Consult applicable electrical codes to make this determination. Avoid mounting the EVAPCO
Controller with a southern exposure. This will minimize the amount of solar heat gain the system will experience and will make it
easier to view the operator interface.
Temperature/Pre ure Sen or In tallation
EVAPCO eco-Air fluid coolers are supplied with a thermowell (1/4” G threads) and a NTC temperature sensor. The thermowell and
temperature sensor should be installed in the common return pipework of the eco-Air fluid cooler unit. Thermowells must be
installed in the horizontal sections of the coil piping. A small amount of thermal paste should be added to the thermowell before the
NTC sensor is inserted to ensure a more accurate fluid temperature measurement.
Figure 1
The suggested temperature sensor location for fluid coolers. Piping shown by dashed lines provided and installed by others.
TEMPERATURE SENSOR TEMPERATURE SENSOR
EVAPCO eco-Air condensers are supplied with a pressure transducer (7/16”-20 UNF threads). The pressure transducer should be
located in the common compressor hot gas discharge pipework. t is recommended that a shut-off valve be located between the
pipework and the pressure transducer to allow the transducer to be more easily replaced should it become damaged.
When the EVAPCO Controller ships factory mounted to the eco-Air unit, the supplied temperature or pressure sensor must be
wired to the junction box location on the connection end of the eco-Air unit (Figure 3). f the EVAPCO Controller does not ship
factory mounted, the supplied temperature or pressure sensor must be wired to the EVAPCO Controller. Consult the supplied
wiring diagram for a determination if the junction box is supplied.
Each EVAPCO Controller is supplied with one ambient air sensor that is located on the bottom of the Controller enclosure. Should
the EVAPCO Controller be placed in a location where the ambient temperature (i.e. indoors) is not indicative of the ambient
temperature of the eco-Air unit, the ambient temperature sensor must be relocated to a more suitable location and the resulting
opening in the enclosure must be sealed with a Type 4 plug.

Wiring Con ideration
Consult the supplied wiring diagram for detailed wiring information. All field wiring is indicated by dashed lines on the wiring
diagram.
All wiring in and out of the EVAPCO Controller should be with copper conductors and wire lengths must be kept as short as
possible. Consult the detailed wiring diagram for field wiring connections of each device. Applicable electrical codes for the
location should be followed during the sizing and installation of the field wiring. All fittings attached to the EVAPCO Controller
must be Type 4. All wiring must be through the bottom of the EVAPCO Controller. Top entry into the EVAPCO Controller is
not permitted. Any damage caused to any component within or connected to the EVAPCO Controller due to a top entry
connection is not warrantable!
For wiring the EVAPCO Controller to each NEMA fan motor, Belden®VFD cable 295XX (XX denotes gauge) or equivalent should
be used. The shield of the VFD cable needs to be bonded to ground at both ends of the cable.
While the EVAPCO Controller does provide provisions for connection to a BAS, this connection is not required for the EVAPCO
Controller to operate.
Operation and Servicing
On eco-Air units equipped with NEMA fan motor(s), the EVAPCO Controller contains a three position selector switch (Bypass-Off-
Auto) located behind the HM door. The operation of each position is as follows:
Auto: The Auto position allows the EVAPCO Controller to operate the eco-Air unit based on the logic programmed into the
Controller. Note that the unit must be switched on before the eco-Air unit will begin to operate. Please see the On/Off Unit
Screen section of this document for more information.
Off: n the Off position, the EVAPCO Controller will be powered; however, output commands will not be sent to any of the
attached equipment. This position is used for programming the VFD.
Bypass: n the Bypass position, the logic program is bypassed which allows the fan motor(s) to energize independent of
sensor temperature or setpoints. Power is routed around the VFD and thus the fan motor(s) will operate at full power, across-
the-line. The VFD will still be energized when the selector switch is in the Bypass position.
The door protecting the HM must be shut unless an operator is using the HM interface. This will protect the HM interface from
contamination and increase the life of the HM .
The EVAPCO Controller is supplied with air filters that must be inspected every 90 days. Depending on the installation
environment, more frequent inspection and/or replacement may be required. A dirty filter can cause the internal panel temperature
to increase and may cause component failure. Permanently removing the filter will allow dirt and particulates to enter the enclosure
and may cause premature failure.
Please consult the proper Operation and Maintenance nstructions for start-up and maintenance guides for the eco-Air unit
attached to the EVAPCO Controller.
