Abstract
A thermostat comprising a software sub-routine for controlling the operation of an air conditioner and a stored value representative of the air conditioner's operating and non-operating time, which is indicative of the outdoor temperature and load on the air conditioning system. The stored value representative of operating time is evaluated by the software sub-routine, which responsively raises the set-point temperature when the stored value exceeds a predetermined level indicative of a high outdoor temperature. The economy feature can be manually enabled, or remotely enabled via an input signal from a phone or Internet connection.
