CLOCK THERMOSTAT WITH MEANS FOR REDUCING THE SETBACK TEMPERATURE

摘要

A clock thermostat apparatus adapted for controlling temperature conditioning apparatus maintains a normal control temperature in a space and during certain selected time periods deviating from the normal temperature control by resetting the normal temperature control to some lower temperature for comfort and energy conservation. The clock thermostat apparatus has a manual temperature selection knob and a manual temperature deviation selection member. A connection is provided between the temperature selecting knob and the temperature deviation selection member to turn the temperature deviation selection member to a lower value to reduce the amount of reset when the temperature selection knob is moved to some predetermined low temperature.
