Abstract (en)
[origin: US4681254A] For use in a radiator space heating system, a thermostatic valve for controlling the flow of heating agent to the radiator is provided with a bypass and at least two auxiliary valves. One auxiliary valve is disposed in the bypass and controlled by the thermostat. The other auxiliary valve is timer-controlled and disposed in series with the thermostatic valve. When temperature reduction is desired, such as during nighttime operation, the timer-controlled auxiliary valve closes, but the bypass auxiliary valve can open when the set-back temperature is reached.
