Auxiliary room temp. control for central heating - has disc divided into conductive segments for operating diodes, timer and electromotor for two radiator thermostats

摘要

The central heating control permits individual, time-dependent room temp. level setting within the normally, automatically- controlled ranges, e.g. setting according to outside temp., lower level for night time, bedrooms etc. The existing radiator thermostats are used as well as additional radiator adjusters. Both types consist of a combination of timer (13), electromotor (12) as well as the thermostat itself. A control disc (4) permits switching at various positions by microswitches or electronic controls. The disc is divided into conductive segments (6) for switching processes in connection with diodes and a contact spring. The latter is connected to one terminal of a relay (8).
