Abstract

A security system and method includes a control panel, a security RF receiver connected to the control panel, an air temperature controller unit (e.g. a furnace and/or an air conditioner) including an air temperature controller RF receiver for receiving RF signals to control its operation, and a wireless thermostat having a unique thermostat identification indicia associated therewith. The thermostat has a thermostat RF transmitter configured to transmit air temperature control signals to the air temperature controller unit via the air temperature controller RF receiver to control its operation in accordance with a preprogrammed air temperature profile. The security system control panel is adapted to receive and monitor signals transmitted from the thermostat RF transmitter and generate a thermostat warning signal under certain preprogrammed conditions. The control panel monitors either or both of (1) the air temperature control signals transmitted by the thermostat RF transmitter or (2) periodic supervision signals in order to determine if a thermostat warning signal should be generated. Remote control of the air temperature controller is enabled by using a remote control device with an RF transmitter for communicating directly with the air temperature controller RF receiver. Also, a security RF transmitter may send control signals directly to the air temperature controller RF receiver without the need to use the wireless thermostat.
