Room heating control is effective to monitor the cooling curve during a period of non-utilisation of the room and, in response thereto, to commence room heating again at an instant appropriate for ensuring that the room will reach the required temperature again substantially at the commencement of the next utilisation period. The actual temperature theta of the room during cooling is subtracted from the utilisation temperature theta N and the difference is integrated and the integral used to determine, from integral values and corresponding heating- up times which are stored in a memory, the time required to heat the room to temperature theta N, the room heater being switched on when the expected heating-up time corresponds with the time remaining before commencement of the next utilisation period. The system is designed to improve its performance with repeated use. <IMAGE> |
