US 6,213,404 B1 · Remote temperature sensing transmitting and programmable thermostat system

Abstract

The present invention is a system of wireless, battery operated temperature sensing devices which transmit ambient or other sensed temperature information to a programmable thermostat. The compact construction and multi-level programming of the temperature sensing devices for only periodic transmission of temperature information to the programmable thermostat permits years of operation with power supplied by small, inexpensive batteries. The temperature sensing devices are therefore easily installed at any location within about 100-200 feet from the programmable thermostat. The present invention also comprises a method of retrofit for the programmable thermostat of U.S. Pat. No. 5,449,319, whereby a compact receiver device is connected to available connections for input of remotely transmitted information and the programming of the programmable thermostat is adapted to receive, store, display and control environmental control devices according to the input temperatures received from the temperature sensing devices.

Dependent claims

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.
