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 at the input and 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 TC5-1N4F1A 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.

One stage of variable speed fans can be connected to the controller, two stages of constant-speed fans, as well as curtains, foggers and heaters can be connected to the controller.

The main features of the TC5-1N4F1A 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.

TEMPERATURE AND MINIMUM VENTILATION SPEED CURVES

The controller can be set to automatically change the temperature set point and the minimum ventilation speed over a given period of time in accordance with the user's requirements by specifying a temperature curve and a minimum ventilation speed curve with up to six different points each.

CHOICE OF TEN MOTOR CURVES

The variation in motor speed resulting from a change in voltage will depend on the make and capacity of the motor. In order to achieve a high degree of compatibility between controller and motor, the user can choose from among ten different motor curves, thus ensuring that the correct voltage is supplied.

HIGH/LOW TEMPERATURE ALARM OUTPUT

TC5-1N4F1A.rev.05

TC5-1N4F1A

HUMIDITY COMPENSATION

The stage 1 minimum speed can be adjusted automatically as a function of relative humidity. As humidity increases, the minimum speed of stage 1 fans increases proportionnally to compensate for the change.

FULL-SPEED FAN START-UP

In order to overcome the inertia of the ventilation system components and de-ice the fan blades in cold weather conditions, the controller supplies maximum voltage to the variable speed fans during the 2 seconds immediately following each start-up.

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.

OUTSIDE TEMPERATURE COMPENSATION ON CURTAIN SPEED

Curtain opening and closing times can be decreased as a function of outside temperature.

OVERLOAD AND OVERVOLTAGE PROTECTION

Fuses are installed at the input and 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.

CONTROL OF AIR INLET MOVEMENT

If the TC5-1N4F1A is used in combination with a PF-5B controller, the movement of the air inlets can be coordinated with the operation of the fans using a potentiometer located on the panel drive. This allows the air inlets to be adjusted correctly, without the influence of uncontrollable factors such as wind or air from adjoining rooms.

TEST MODE

A test mode allows you to simulate temperature changes and verify controller performance.

OTOR TYPES

The relationship between the voltage supplied to a motor and its operating speed is described by a motor curve. This curve varies with the make and capacity of the motor. The various motors available in the industry have been divided into ten categories and the controller has been programmed with a different motor curve for each of these categories. To ensure that the controller supplies the correct voltages, an appropriate curve must be selected for Stage 1 according to the type of fan motors used.

Selecting a Motor Type for Stage 1

Refer to the list of motors enclosed with this user's manual to determine which curve number (1 to 10) is appropriate for the type of motors used.

n

UMIDITY COMPENSATION

The stage 1 minimum speed can be adjusted automatically as a function of relative humidity. As humidity increases, the stage 1 minimum speed increases proportionally to compensate for the change. At humidity levels at or below the humidity set point, stage 1 minimum speed is equal to the normal uncompensated speed. The user specifies the percentage increase in minimum speed for a relative humidity equal to the humidity set point +

10%. For example, if the minimum speed is 40% and the compensation adjustment is 30%, the minimum speed will be adjusted to 70% of full speed when the humidity rises 10% above the humidity set point. In addition to adjusting the minimum speed, the humidity compensation feature also changes the operation of the minimum ventilation cycle: if the controller is operating in minimum ventilation mode when the relative humidity exceeds the humidity set point, the minimum ventilation fans are operated continuously rather than cycled.

INIMUM VENTILATION SPEED CURVE

The user can define a minimum ventilation speed curve to adjust the Stage

1 minimum speed automatically over a given time period. Each curve is defined by six points. Each point specifies a day number and a fan speed for that day. Once the points are defined, the minimum speed curve must be activated. When the minimum speed curve is activated, the controller adjusts the Stage 1 minimum speed every hour in a linear fashion between two consecutive points.

When the last point of the curve is reached, the curve is deactivated. The controller maintains the minimum speed specified for this point until the curve is reactivated or until a new single minimum speed is specified using the first method.

Interaction Between Temperature and Minimum Speed

Curves

•

The minimum speed curve can be activated only if the temperature curve is already activated

•

All points of the minimum speed curve other than the first one are automatically given day numbers identical to those specified for the temperature curve. Only the first point of the minimum speed curve has an adjustable day number. This day number must be greater or equal to the day number specified for the first point of the temperature curve and less than the day number specified for the second point of the temperature curve (see example 1).

If you activated the temperature curve yesterday, the current day number of the temperature curve is d6. Therefore, if you activate the minimum speed curve today, it will effectively be in operation in 4 days, when the current day number of the temperature curve reaches d10. In the meantime, the fans will run at the specified single minimum speed

(see example 2).

•

If you activated the temperature curve six days ago, the current day number of the temperature curve is d11. Therefore, if you activate the minimum speed curve today, it will effectively be in operation the moment you activate it. In this case, the current minimum speed will be a value between 10% and 20%.

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 cut-off 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 cutoff 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.

TC5-1N4F1A

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.
