Features - Airstream TC5-2V4SA User Manual

FEATURES

The TC5-2V4SA 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.
Two stages of variable speed fans can be connected to the controller, as
well as two stages of constant-speed fans and two stages of either con-
stant-speed fans or heating units. In addition, one of the constant-speed fan
stages can be configured as a mist cooling stage.
The main features of the TC5-2V4SA 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 TYPES
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 types, thus ensuring that the correct voltage is supplied.
