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 means and a manual temperature deviation selection means for selecting the normal control temperature and the amount of reset or deviation during the selected time period. A connection means is provided between the temperature selecting means and the temperature deviation selection means to turn the temperature deviation selection means to a lower value when the temperature selection means is moved to some predetermined low temperature. When the normal control temperature selection is reduced by the temperature selection means, the temperature maintained is not reset to a low temperature during a setback time period which might be so low that freezing of water pipes would result in the space wherein the temperature is being controlled.
An improvement in an electric clock thermostat having a control point selector for selecting the normal temperature to be maintained in a space when the thermostat is connected to a space conditioning temperature apparatus, a deviation selector for selecting the amount of temperature deviation desired from the normal selected temperature control point, and an electric time mechanism for selecting a certain time period during which the temperature control point deviates from the normal setting by the amount of the selected deviation, the improvement comprising,
In a clock thermostat adapted for controlling temperature conditioning apparatus to maintain a normal control temperature in a space and during certain selected time periods deviating from the normal control temperature comprising
An improvement in a clock thermostat adapted for controlling temperature conditioning apparatus to maintain a normal temperature in a space as selected by a temperature selection means during a first selected time period as established by a timer means, means including said timer means for resetting the normal temperature to a lower temperature by an amount selected by a temperature setback selection means during a second selected time period, the improvement comprising,
