Clock thermostat apparatus for resetting the temperature of a space during selected time periods with means for varying the pickup time as a function of the drop in space temperature during the setback period

摘要

A clock thermostat apparatus for controlling the temperature in a space at different temperatures depending upon the time period of the time controlled apparatus has a second temperature responsive apparatus responsive to space temperature for determining the pickup time required to bring the temperature of the space back to normal after a period of setback. When the space temperature drops a small amount, the pickup time for bringing the space back to a normal temperature is short; however, during cold weather conditions when the space temperature drops a large amount, a greater pickup time period is scheduled.
