ABSTRACT:
A temperature offset control system having a central control station wherein temperature limits can be set for the desired amount of offset for both heating and air conditioning systems. A centrally located temperature sensor reads the ambient temperature within the house. A comparator compares this sensed temperature with the offset temperatures and produces a control signal responsive to the comparison. The control signal is then transmitted through the existing house wiring to receivers associated with each heating and/or air conditioning unit, whereby the heating unit will receive the control signal and will respond when that control signal resulted from a sensed temperature crossing the lower end of the temperature limits set at the central control station to thereby turn on and off. The air conditioning unit will receive the same control signal and it will turn on and off in response to receiving a control signal resulting from a temperature crossing at the upper end of the temperature range set at the central control system.
