override status those skilled in the art will recognize that in addition to the foregoing data the wireless thermostat can also transmit a variety of other environmental data the system also permits long term site monitoring by automatically outputting temperature rssi and bssi each minute we turn now to a detailed discussion of the figures referring to fig1 this figure shows a preferred embodiment of the invention in which a plurality of remote sensor units 4 e g wireless thermostats communicate with a base transceiver 2 which in turn provides information to an air conditioning and or heating unit 1 the air conditioning and or heating unit 1 may be any one of a number of commercially available air conditioning and or heating units the base transceiver 2 would preferably communicate with the air conditioning and or heating unit 1 via hardwired cable 3 each remote sensor 4 independently communicates with the base transceiver 2 via wireless transmission links 5 in the preferred embodiment the wireless transmission links 5 have 20 separate frequency channels available as will be described more fully below the base transceiver 2 and the remote sensor 4 will scan frequency channels to select the frequency channel which has acceptable transmission quality each remote sensor 4 also has a unique binding address which is used to identify it to the base transceiver 2 these.
