Central heating with preset adjustment of individual rooms - uses heating or cooling of thermostat to allow temperature control according to room and time

摘要

Method of adjusting required room temp. which is produced by a thermostat-controlled radiator is carried out without varying the control range of the thermostat, by controlled the heat energy supplied to the room by output control means acting on the heat release of the radiator. This may be carried out by producing a control temp. in the region of ther thermostat, which together with the room temp. produces a mixed temp. corresponding to the control range of the thermostat. a mixed temp. above from temp. may be produced at the thermostat by a heating coil, which also produces a constant control temp. above mixed temp. Alternatively, a mixed temp. below room temp. may be produced by cooling the thermostat.
