Abstract

A wireless thermostat adapter system (10) includes a thermostat interface (11) and an HVAC interface (12). A two-way wireless communication is effected between the thermostat interface and the HVAC interface through a conventional RF signal. The thermostat interface also includes an electrical circuit (26) with an antenna (27), a set of six flexible thermostat coupling wires (28) which are coupled to the thermostat, and a short range RF transceiver (29). The HVAC interface includes an electrical circuit 38 which is adapted to be coupled to a HVAC systems (14). The HVAC interface circuit includes an antenna (39) and a set of six HVAC wire terminals (40) which coupled the HVAC interface with the HVAC. The HVAC interface also includes a short range RF transceiver (41) coupled to the antenna (39).
