TC5-8SDA rev.03

We strongly recommend installing supplementary natural

ventilation as well as a back-up thermostat on at least one

cooling stage (refer to the wiring diagram enclosed with this

user's manual to connect the thermostat).

Although fuses on the outputs of the controller protect its

circuits in case of an overload or overvoltage, we recommend

installing an additional protection device on the controller's

supply circuit.

The room temperature where the controller is located MUST

ALWAYS REMAIN BETWEEN 32°F AND 104°F (0°C TO

40°C).

To avoid exposing the controller to harmful gases or excessive

humidity, it is preferable to install it in a corridor.

DO NOT SPRAY WATER ON THE CONTROLLER

4TC5-8SDA rev.03

The TC5-8SDA is an electronic device used for environmental control in

livestock buildings. It allows the user to maintain a specified target

temperature by controlling the operation of ventilation and heating

equipment. Six stages of constant-speed fans or mist units and two

stages of either constant-speed fans or heaters can be connected to the

controller. In addition, the last cooling stage can be configured as a mist

stage.

The main features of the TC5-8SDA are as follows:

THREE-DIGIT DISPLAY

A three-digit display provides a high level of accuracy, allowing the user

to specify a temperature to within one tenth of a degree (in Fahrenheit

or Celsius units).

PILOT LIGHTS

Pilot lights indicating the state of outputs allow the user to monitor the

operation of the system without having to enter the building.

MINIMUM VENTILATION CYCLE

When ventilation is not required for cooling, the first stage fans can be

operated either continuously or intermittently to reduce the level of

humidity and supply oxygen to the room.

RAMPING OPTION ON STAGE 1

The running time of the fans can be increased (or decreased) gradually to

smooth out the transition between the minimum cycle and full operation

of Stage 1 fans.

MINIMUM VENTILATION COMPENSATION CURVE

An outside probe can be connected to the controller to adjust the

minimum ventilation cycle as a function of outside temperature.

FEATURES

TC5-8SDA

TEMPERATURE CURVE

The controller can be set to automatically change the temperature set

point over a given period of time in accordance with the user's

requirements by specifying a temperature curve with up to six differ-

ent points.

HUMIDITY COMPENSATION

When the humidity level is high, an additional fan stage can be used to

dehumidify the building. Mist units can also be turned off automati-

cally when the humidity is too high.

HIGH/LOW TEMPERATURE ALARM OUTPUT

FOUR INDEPENDENT TEMPERATURE PROBE INPUTS

Up to four temperature probes can be connected to the controller in

order to obtain a more accurate reading of the average room tempera-

ture and a faster reaction time.

OVERLOAD AND OVERVOLTAGE PROTECTION

Fuses and other protection devices are installed on the outputs of the

controller to protect its circuitry in the case of an overload or over-

voltage.

COMPUTER CONTROL

The controller can be connected to a computer, thus making it pos-

sible to centralize the management of information and diversify

control strategies.

TEST MODE

A test mode allows you to simulate temperature changes and verify

controller performance.

INTERNAL SWITCHES

The internal switches are located on the inside of the front cover.

When the controller is shipped from the factory, all the switches

are set to OFF.

INSTALLATION

MOUNTING INSTRUCTIONS

Open the latch and lift the cover. Remove the black caps located on

each of the four mounting holes. Mount the enclosure on the wall

using four screws. Be sure the electrical knockouts are at the bottom

of the enclosure in order to prevent water from entering the control-

ler. Insert the screws in the mounting holes and tighten. Fasten the

four black caps provided with the controller onto the four mounting

holes. The enclosure must be mounted in a location that will allow the

cover to be completely opened right up against the wall.

CONNECTIONS

To connect the controller, refer to the wiring diagram enclosed with

this user's manual.

Set the voltage switch to the appropriate voltage.

Use the electrical knockouts provided at the bottom of the

enclosure. Do not make additional holes in the enclosure,

particularly on the side of the enclosure when using a computer

communications module.

It may be necessary to install a transformer in order to supply

the appropriate voltage to the heating unit.

ALARM CONNECTION: There are two types of alarms on the mar-

ket. One type activates when current is cut off at its input, whereas

the other activates when current is supplied at its input. For an alarm

of the first type, use the NO terminal as shown on the wiring diagram.

For an alarm of the second type, use the NC terminal.

ALL WIRING MUST BE DONE BY AN AUTHORIZED

ELECTRICIAN AND MUST COMPLY WITH APPLICABLE

CODES, LAWS AND REGULATIONS. BE SURE POWER IS

OFF BEFORE DOING ANY WIRING TO AVOID ELECTRI-

CAL SHOCKS AND EQUIPMENT DAMAGE.

TEMPERATURE PROBES

Connecting the Probes

The controller is supplied with one temperature probe connected to input

# 1. Three additional room probes can be connected to inputs # 2, 3 and

4 and an outside probe can be connected to input # 5 (see wiring

diagram enclosed).

CAUTION: Probes operate at low voltage and are isolated from the

supply. Be sure that probe cables remain insulated from all high voltage

sources. In particular, do not route the probe cables through the same

electrical knockout as other cables. Do not connect the shield from the

probe cable to a terminal or a ground.

Switches are used to activate or deactivate

the additional probes connected to the con-

troller.

Activate each additional probe by setting

the appropriate switch to ON:

• Switch # 3 activates the probe connected to input # 2.

• Switch # 4 activates the probe connected to input # 3.

• Switch # 5 activates the probe connected to input # 4.

Extending the Probes

Each probe can be extended up to 500 feet (150 meters). To extend a

probe:

Use a shielded cable of outside diameter between 0.245 and 0.260

in (6.22 and 6.60 mm) (the cable dimensions should not be under

18 AWG) to ensure the cable entry is liquid tight. Do not ground

the shielding.
