Controlling Temperature

Heating mode:
The ON temperature is set lower than the OFF temperature and the relay is energized to turn ON a heating device of some type such as a heat lamp which goes back off once the OFF temperature is reached.

Cooling mode:
The ON temperature is set higher than the OFF temperature. The relay is energized to turn ON a cooling device of some type such as a fan. It turns back off once the OFF temperature is reached.

Controlling Humidity

Humidify Mode:
The ON humidity is set lower than the OFF humidity level.  The relay is energized to turn on a humidity increasing device of some type such as a humidifier that is turned back off once the higher OFF humidity level is reached.

Dehumidify Mode:
The ON humidity is set higher than the OFF humidity level.  The relay is energized to turn on a humidity lowering device such as a dehumidifier which is turned off once the lower OFF humidity level is reached
