Abstract

An anti-freeze device (23) is connected to the same external sensor (13) as a heating system controlled as a function of the external temperature, and allows the room temperature to drop significantly during operating breaks by switching off the burner (2) via a bistable switching element (25, 28). A first switch device (19) operates an actuator (4, 14), a second switch device (20) raises the boiler temperature in a continuously variable manner with the heating flow temperature, and a third switch device (21) provides for a minimum boiler temperature as corrosion protection. The switch devices (19, 20, 21) act on an AND and OR element (30 and 35). <IMAGE>
