The device has mechanical control units such as pressure and temperature sensitive control units (6,7). The units are connected with one another to a connecting part (8), which serves as an actuator for an electrical activating switch (13) of a heating unit, such that the part keeps the electrical switch closed, when both conditions are together fulfilled. Temperature, which lies below preset temperature limit values, acts on the unit (7), during opening of the switch, when one of both conditions is not fulfilled. The temperature sensitive control unit is designed as a bimetal diaphragm. |
