DC powered Natural Ventilation Control.

Description

This 12-Volt DC powered Phason Natural Ventilation Control (NVC-2-12) 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-2-12 maintains the curtain position
  • When the temperature rises above the idle band, the NVC-2-12 opens the curtain for the on duration and then pauses for the off duration
  • After each off duration, the NVC-2-12 checks the temperature and then either opens or closes the curtain, depending on the temperature

Controlling a Heater or Furnace:

  • When the temperature is below the heat set point, the NVC-2-12 switches the heater on; when it is above the set point, the NVC-2-12 switches the heater off
