The BTC201 temperature controller can turn on/off an electric appliances at desired temp.

For example, you can use the controller to turn on/off a heater and a fridge to keep temp around 100 F. Turn on heater at 98.5 F. Turn on fridge at 105 F. Turn off the heater/fridge when temp reaches 100 F. The setting is (SV=100, Cd=5, Hd=1.5). the controller itself doesn't change temp.
