Abstract
At least first and second thermostats may be operably coupled to one another and are capable of sharing their target temperatures and their temperature signals. The first thermostat may provide a thermostatic control signal to the air temperature control system. In some embodiments at least one thermostat further comprises a target-temperature-modifying occupant presence detector. Some embodiments further comprise first and second air movement control devices operably coupled to and controlled by the first and second thermostats, respectively. The operation of the stages of a multistage air temperature control system may be controlled.
