TC5-1N5FAB rev.06
The TC5-1N5FAB is an electronic device used for environmental control in
livestock buildings. It allows the user to maintain a specified target tem-
perature by controlling the operation of ventilation and heating equipment.
One stage of variable speed fans, up to two stages of constant-speed fans,
as well as curtains, foggers and heaters can be connected to the controller.
The main features of the TC5-1N5FAB 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 Cel-
sius 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 oper-
ated 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 mini-
mum 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.
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 proportionally to compensate for the change.

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 ventila-
tion 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 accor-
dance 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.
