| 摘要 |
The invention relates to control apparatus 1 for controlling a heating system (not shown) wherein the heating system is supplied with heating medium from a separately controlled heating system, the control apparatus 1 comprises first sensor means 2 for sensing the temperature of a heating medium in a separately controlled system, second sensor means 3 for sensing the ambient temperature around the heating system, and control means 4 to control the flow of heating medium to the heating system in response to signals from the first and second sensors. Preferably, the sensors 2 and 3 are thermostats. The heating medium may comprise a fluid, wherein control means 4 is a pump. A thermostatic mixing valve may mix heated and non-heated fluid. A heat exchanger, possibly comprising an underfloor heating element, may be provided.
