Phason NVC-2

Natural Ventilation 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.
