Abstract

A wireless air conditioning control system is provided. A thermostat assembly measures ambient temperature in an area to which an air conditioning system provides conditioned air. It compares the measured ambient temperature with a predetermined target temperature and wirelessly transmits air conditioning request signals to an air conditioning control assembly responsively to the comparison. The thermostat assembly and the air conditioning control assembly may be automatically mated with one another so that the air conditioning control assembly responds to air conditioning request signals only from a particular thermostat assembly. Where a plurality of transmitters are present, their transmissions are staggered to avoid data collision. The control assembly includes a freeze protection mechanism to protect against freezing conditions in the absence of air conditioning request signals. A battery powered thermostat assembly is intermittently partially shut down to reduce power consumption. The transmitter assembly predicts temperature to account for thermal inertia.
