Abstract:
A system of battery operated remote temperature sensing transmitters, receiver means and a programmable thermostat comprising:(a) each battery operated remote temperature sensing transmitter comprising temperature sensing means, power supplied solely by a battery power supply, sensed temperature storage means and transmission means whereby a sensed temperature is stored and the value transmitted periodically such that battery operation of the transmitter is capable of being maintained without battery replacement for at least several months;(b) receiver means for receiving and uniquely identifying and storing transmitted temperatures from one or more transmitters; and(c) programmable thermostat means connected operatively with the receiver means whereby sensed temperatures stored in the receiver means are retrieveable by the programmable thermostat means for use by one or more functions of the programmable thermostat means.
