The thermostat for the AVANSA TH2 circulation pump is used to switch the ignition on or off, most often the electrical contact (pump phase). Turns the circulation on and off. Therefore, the pump is easily regulated, for example, by the boiler circuit of a solid fuel boiler, or by filling a tank or a hot water boiler. The thermostat can be easily placed on the pipe and connected to the other side so that it does not loosen. There is a bimetal in the thermostat that activates the on or off contact.
