Abstract
A thermostat control system having remote devices and/or other internally powered devices provides transmissions at different power levels and at different data transfer rates to conserve power life. Thermostat control system components and devices may be powered by replaceable power supplies that are conserved by transmitting at a lower power level more often than at a higher power level. A higher power level transmission is provided at a lower data transfer rate, and a lower power level transmission is provided at a higher data transfer rate. A higher power transmission is provided periodically to ensure reliable communication of temperature information.
