PRECAUTIONS

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

FOR CUSTOMER USE

Enter the serial number located on the side of the controller below for future reference.

FEATURES

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.

TC5-8SDA.rev.02

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 different 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 automatically 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 temperature 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 overvoltage.

COMPUTER CONTROL

The controller can be connected to a computer, thus making it possible 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.

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 controller. 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 market. 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.

!

WARNING

ALL WIRING MUST BE DONE BY AN AUTHORIZED

ELECTRICIAN AND MUST COMPLY WITH APPLICABLE

CODES, LAWS AND REGULATIONS. BE SURE POWER IS

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 controller.

ON

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.

2

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.

10

TC5-8SDA.rev.02

TC5-8SDA

It is preferable to solder the cable joint to ensure a proper contact between the two cables.

CAUTION: Do not run probe cables next to other power cables.

When crossing over other cables, cross at 90°.

3

Installing the Outside Probe

Run the outside probe cable on the north side of the building, 6 ft

(2 m) below the eave, inside a pale colored conduit. Avoid installing the probe in direct sunlight or exposed to the rain.

Be sure the probe cable is isolated from sheet metal or any other conductive material.

Be sure no cable joint is exposed to air or water.

CHANGING THE PARAMETER SETTINGS

USING THE DISPLAY

Flashing Values: The display will flash in certain cases and not in others. The flashing indicates that the value shown can be adjusted. A value that is not flashing cannot be adjusted.

78.0

Relative and Absolute Values: Some parameter adjustments are displayed both as a relative value and an absolute temperature. This applies to all heating and cooling differentials, the mist differential and the mist and heater offset. The parameter is first displayed as a relative value. The corresponding absolute temperature is displayed after six seconds if no action is taken by the user. The absolute value is the temperature at which the stage turns on (except in the case of the heater and mist offsets where the value displayed is the temperature at which the stage turns off). If the user turns the adjustment knob, the relative value reappears. For example, when the user turns the selection knob to the differential position

COOLING- DIFF 2-8, the sequence is as follows:

(i) The current differential for stage 2 flashes on the display, alternating with "St .2".

Days

A curve is defined using six points. Each point specifies a day number and a set point for that day. Once the points of the curve are defined, the curve must be activated. The controller will change the temperature set point every hour in a linear fashion between consecutive points of the curve. When the last point of the curve is reached, the temperature set point for that day is maintained until the curve is reactivated.

NOTES : i) All six points of the curve must be specified. If six points are not needed, repeat the last temperature value for each unnecessary point.

ii) Certain restrictions apply to reduce the risk of errors:

- The highest possible day number is 99.

- Decreasing day numbers are not allowed.

- Increasing temperatures are not allowed.

- The temperature variation cannot exceed 3°F (1.6°C) per day.

MINIMUM VENTILATION CYCLE

PRINCIPLE OF OPERATION

When the room temperature is below the set point, the Stage 1 fans operate according to the minimum ventilation cycle. Running the fans even though ventilation is not required for a cooling purpose is useful to reduce humidity levels and supply oxygen to the room. It also prevents the fans from freezing in winter.

Minimum Ventilation Cycle Settings

1. To run the fans continuously at minimum speed, set time off to zero and time on to any value other than zero.

2. To stop the fans, set time on to zero and time off to any value.

3. To run the fans intermittently, set time on to the desired running time and time off to the desired off time.

RAMPING OPTION

The user has two options for controlling the transition from the minimum ventilation cycle to full operation of the Stage 1 fans, i.e. in the temperature interval between the set point and the set point + Stage 1 differential. In the first option (ramping), the running time of the fans is increased (or decreased) gradually to smooth out the transition between full operation of Stage 1 fans and the minimum cycle. In the second option, no transition is made from the minimum cycle to full operation of the Stage 1 fans. The running time of the fans is simply defined according to the minimum ventilation cycle.

Indoor Temperature

This option is activated when ramping is turned off. When the temperature is less than the set point + differential 1, Stage 1 fans run according to the minimum cycle (see above). When the room temperature reaches point A, stage 1 fans run continuously with no transition.

When the temperature decreases to the set point, Stage 1 fans start operating according to the minimum ventilation cycle.

* When Time Off becomes less than 15 seconds, it is fixed at 15 seconds until the temperature has reached the set point + differential 1. At that point, the stage 1 fans operate continuously.

OUTSIDE TEMPERATURE COMPENSATION

The TC5-8SDA has the capability of automatically adjusting the running time of the minimum ventilation fans as a function of outside temperature. As the weather gets colder, the on time is decreased gradually to compensate for the change. This can help reduce costs by reducing the ventilation when it is not required. A curve is used to calculate the required compensation as a percentage of current on time (see following page). Only the running time is adjusted; the total cycle time remains unchanged. Note that internal switch # 6 must be set to ON for this feature to work.

ZONED HEATERS

To configure your system for zoned heaters, set dipswitch # 9 to ON.

Since the two heater outputs function independently, different probes are assigned to each output: Probes 1 and 2 are assigned to Heater 1 and Probes 3 and 4 are assigned to Heater 2. Individual probes can be turned on or off using the dipswitch settings. If both probes are activated for a given heater, the average temperature from both probes is used. To use stages 7 and 8 for heating, set internal switches # 7 and 8 to ON. To use only stage 8 for heating, set internal switch # 7 to ON and # 8 to OFF.

Both heating zones can have negative and positive heater offsets. A negative offset is used when controlling heat mats, for example.

To avoid ventilation problems when using zoned heating, a special protection is built into the device. Suppose the animals are young and confined to one part of the building (zone 1) while the rest of the building is heated at a minimum level (zone 2). If the temperature

GLOSSARY

BANDWIDTH: The temperature interval within which the variable-speed fans of a given stage increase or decrease in speed proportionally to the temperature.

CASCADING HEATERS: Heaters operate in a sequence. As the average room temperature drops, additional heaters are turned on as needed.

CURTAIN DEAD BAND: The dead band is the temperature difference between the opening and closing temperatures of the curtains. Within this interval, the curtains are at rest.

DEFAULT VALUE: A typical parameter setting defined at the factory.

DIFFERENTIAL: The differential is the temperature difference between the moment the constant-speed fans or heating units of a given stage start running and the moment they return to a stop.

HYSTERESIS: A hysteresis is used to smooth the transition from one state to another. For example, when the temperature drops to the cutoff point for a stage of constant-speed fans, the fans will actually be cut off at slightly less than the cut-off point. This way, if the temperature fluctuates around the cut-off point without dropping significantly below it, the controller will not oscillate between two states. For example, if the hysteresis is 0.3°F and the stage 2 fans are programmed to be cut off at 75°F, the cut-off will actually occur at 74.7°F.

MINIMUM VENTILATION CYCLE: When the room temperature is below the set point, the Stage 1 fans operate intermittently to provide minimum ventilation to the room.

MINIMUM VENTILATION SPEED CURVE: When Stage 1 operates variable-speed fans, they will run at minimum speed during the minimum ventilation cycle. The user can define a minimum ventilation speed curve to adjust the Stage 1 minimum speed automatically over a given time period. The minimum speed increases over time as the animals grow.

OFFSET: An offset is a temperature difference from the set point that normally defines a cut-off point for a stage operation. For example, a heater offset of 2°F means the heaters will turn off at

2°F below the set point.

RAMPING ON STAGE 1: When the temperature rises to the point where Stage 1 constant-speed fans are needed for cooling, the running time of the fans is increased gradually from the minimum ventilation settings up to full operation. Likewise, when the temperature drops below the set point, the running time is decreased gradually until the minimum ventilation settings are reached.

SET POINT: The set point is the target room temperature. When the temperature is above the set point, the controller cools the room by turning on the cooling fans. When the temperature is below the set point, the controller heats the room by turning on the heaters.

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. The set point decreases over time as the animals grow.

ZONED HEATERS: When zoned heaters are used, heaters in each zone operate according to their own probes rather than the average temperature for the entire room. In this way, heaters across zones are independent of one another.
