Abstract

1384540 Automatic control of temperature WORCESTER ENG CO Ltd 30 May 1972 [12 June 1971] 27614/71 Heading G3R In a central heating system, in order to prevent overheating of a boiler B if a thermostat CS on the H.W (hot water) cylinder opens, thereby closing a motorized valve M in the H.W. circuit (which prevents circulation of heated water through the H.W. cylinder), when a room thermostat R.S. is also open so that the C.H. (central heating) circuits are also inoperative to dissipate the heat content of the boiler B, the resulting de-energization of relays R 1 R 2 in series with CS and R.S. respectively causes energization of a timed relay R 3 via R 1-3 and R 2-2 . Thereby the central heating pump P is restarted and will run for a pre-set time of say 2 mins to dissipate boiler heat content and prevent overheating. Simultaneously, the boiler is shut down by the opening of contacts R 2-1 when the Relay R2 is de-energized. During summer operation when hot water only is being used, the relay R 3 is ineffective and the boiler control thermostat (not shown) is set at a lower level. The system includes a programming unit for wall mounting and incorporating a switch H.W. for switching ON the hot water circuit and a switch C.W. for switching ON the central heating circuit, a time switch T, the relays R 1 R 2 R 3 and indicating light IL1, IL2, IL3.
