This diagram shows how to wire a humidistat.
3. Replace the metal cover plate over the thermostat wiring box and fasten securely.
4. The thermostat setting determines the temperature at which the ventilator turns “on”. The ventilator automatically turns off
when the attic temperature is 10 O F lower than the thermostat. If you want the ventilator to operate at a different
temperature, insert a screwdriver into the slot and turn the indicator to the desired temperature.
The ventilator will now turn “ON” at this temperature and “OFF” 10 0F lower.
