The Ministat is a compact thermostat that offers On/Off control.
An On/Off thermostat switches power to the heater around a set point which is known as a switching differential.
This is commonly 1 degree celsius. This allows for a 0.5 degree swing either side of the set point.
The Ministat is available in 2 different versions. The Ministat 100 has a maximum load of 100w whilst the Ministat 300 is capable of handling loads up to 300w.
