Improved override function that has LED status indicator lights
and allows the user greater flexibility.
MODE OF OPERATION
When the 'AUTO' light is on this sensor automatically operates the roof ventilation unit - opening when the preset room temperature is reached and closing when the temperature drops to a set level.
If you want to temporarily override the automatic operation - press the 'OPEN' or 'CLOSE' button once and the relevant light will come on as the unit responds.
After 20 minutes the unit will revert to automatic control.
Pressing the 'OPEN' or 'CLOSE' button once during the override period will restore automatic control and the 'AUTO' light will come back on.
The units provide automatic controlled ventilation to cool the room overnight during hot weather and close automatically in cold weather so can be left on 'AUTO' throughout the year.
