DETAILS
Effective curtain machine and heater control
The Natural Ventilation Control automatically controls the temperature in a room by operating a curtain machine and heater or furnace according to your programmed settings.
Controlling a curtain machine
- When the temperature is within the idle band, the NVC-2 maintains the curtain position.
- When the temperature rises above the idle band, the NVC-2 opens the curtain for the on duration and then pauses for the off duration.
- After each off duration, the NVC-2 checks the temperature and then either opens or closes the curtain, depending on the temperature.
Controlling a heater
When the temperature is below the heat set point, the NVC-2 switches the heater on; when it is above the set point, the NVC-2 switches the heater off.
