Programming the Thermostat for Poultry Lighting

First of all, if you intend to use this thermostat as a timer switch outdoors, the unit must either by well insulated (to prevent it falling below 5 degrees Celcius on cold nights) or modified to override the internal thermometer.

The following programme settings should be used (following the instructions in the user manual) to have the lights switched on from 4:00am until 7:00pm every day:

If you would like to have the lights turned off automatically when the natural daylight is bright enough (in order to save electricity), consider purchasing one of our adjustable Light/Dark Sensor Circuits.
