Energy saving thermostat with means to shift offset time program
First Claim
1. A thermostat adapted to be connected to a remote temperature conditioning apparatus for controlling the temperature of air in a space to maintain a first temperature during a first period of time and a second temperature during a second period of time, comprising,temperature responsive means responsive to a space temperature,control circuit means adapted to be connected to the temperature conditioning apparatus,means connecting said temperature responsive means to said control circuit means for establishing a control temperature to maintain the first temperature in the space,single button manually settable electronic time interval means for providing a second period of time,means connecting said time interval means to said control circuit means to change said control temperature to maintain a second temperature in the space for said second period of time at a predetermined starting time each day, anddriving means connected to said settable electronic time interval means for changing said predetermined starting time of said second period of time.

1. A thermostat adapted to be connected to a remote temperature conditioning apparatus for controlling the temperature of air in a space to maintain a first temperature during a first period of time and a second temperature during a second period of time, comprising,
temperature responsive means responsive to a space temperature, control circuit means adapted to be connected to the temperature conditioning apparatus, means connecting said temperature responsive means to said control circuit means for establishing a control temperature to maintain the first temperature in the space, single button manually settable electronic time interval means for providing a second period of time, means connecting said time interval means to said control circuit means to change said control temperature to maintain a second temperature in the space for said second period of time at a predetermined starting time each day, and driving means connected to said settable electronic time interval means for changing said predetermined starting time of said second period of time.

8. An improvement in an energy saving thermostat, comprising,
a temperature responsive means adapted to respond to space temperature, a control circuit connected to said responsive means and having an output adapted to be connected to a temperature conditioning apparatus for changing the temperature of the space, temperature control point setting means connected to said control circuit to select the temperature being controlled in the space, setback means connected to said control circuit to select a second temperature to be controlled in the space, timer means connected to said setback means for selecting a time period at a predetermined starting time during which the second temperature is to be maintained having manually operated time interval counter means providing an electric pulse for each increment of time for setting said timer, and indication means providing an indication of each pulse for counting said increment of time, the improvement comprising manually operated means for shifting the starting time of said manually operated time interval counter means and thus changing said predetermined starting time of said time period during which said second temperature is maintained.
