Thermostat control system providing power saving transmissions

An improved thermostat control system having one or more battery powered wireless remote temperature sensors, the improvement comprising:

• one or more remote temperature sensors that are capable of sensing temperature, said sensors having transmitters that transmit signals at a lower power level and a higher power level, said signals comprising temperature information and a unique identification code and user-assigned code associated with each of the one or more remote temperature sensors, the one or more remote sensors controlling said transmitter to successively alternate between transmitting a high power transmission signal and transmitting a set of low power transmission signals, followed by transmitting another high power transmission signal and transmitting a set of low power transmission signals, in continuous succession such that the transmitter transmits at least a predetermined number of signals at the lower power level for every signal transmitted at the higher power level, to thereby ensure at least one transmission at a high power transmission level is reliably received in a given number of successive transmissions, whereby the one or more remote sensors transmit signals only when the sensed temperature changes by more than a predetermined amount such that battery consumption is reduced;
• a processor for controlling the operation of the thermostat;
• a receiver means within the thermostat for receiving and identifying transmitted signals that comprise a unique identification code, the receiver means being configured to communicate to the processor only those signals that comprise one of a select set of unique identification codes, wherein the remote sensor is configured to transmit the temperature information at a first data transfer rate and a second data transfer rate, and the receiving device is configured to receive the temperature information at the first data transfer rate and second data transfer rate.

A thermostat control system having one or more battery powered wireless remote temperature sensors, the thermostat control system comprising:

• one or more remote temperature sensors that are configured to sense temperature, each of said transmitters including a transmitter that transmits signals at both a lower power level and a higher power level, said signals comprising temperature information, the one or more remote sensors controlling said transmitter to successively alternate between transmitting a high power transmission signal and transmitting at least ten low power transmission signals, followed by transmitting another high power transmission signal and transmitting at least ten low power transmission signals, in continuous succession, such that the transmitter transmits a greater ratio of signals at the lower power level than signals transmitted at the higher power level;
• a processor for controlling the operation of the thermostat;
• a receiver means within the thermostat for receiving and identifying the transmitted signals, wherein the processor stores the transmitted temperature information for use in controlling the operation of the thermostat, wherein the one or more remote sensors are configured to transmit the temperature information at a higher data transfer rate for signals transmitted at the lower power level, and at a lower data transfer rate for signals transmitted at the higher power level.
