ABSTRACT:
A timer-controlled thermostat, being set for a lower room temperature, actuates a miniature heating element beneath and in close proximity to an existing thermostat that controls the heating system in a building. The heat radiated from the miniature heating element shuts down the existing building thermostat until the room temperature drops below the temperature at which the timer-controlled thermostat is set, whereupon the miniature heating element is de-energized and the building thermostat senses the lower room temperature and turns the building heating system back on. This cycling continues throughout the timed period. Control of an air conditioning system is accomplished by inserting a controlled relay box between the wall power receptacle and a plug-in type air conditioner power cord, or by incorporating a thermo-electric cooler to produce a cooling effect to control the thermostat used in a central air conditioning system.
