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 10OF 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” 10OF lower.
