FEATURES

The TC4-NVS is an electronic device used for environmental control in live-
stock buildings and greenhouses. It allows the user to maintain a specified
target temperature by controlling the operation of ventilation and heating
equipment. One stage of either constant-speed fans, heating units or mist
sprinklers, as well as curtains for natural ventilation, can be connected to
the controller.
The main features of the TC4-NVS 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 INDICATING STATE OF OUTPUTS
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 continously or intermittently to reduce the level of humidity and
supply oxygen to the room.
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.
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.
