Abstract:
A thermostat adapted to be connected to a climate control system for operating the climate control system, the thermostat comprising a main unit having a microprocessor, a keypad connected to the microprocessor for operating the thermostat, and a sub-base, the sub-base being adapted to communicate with at least one remote temperature sensor and provide information from the at least one remote temperature sensor to the microprocessor, the sub-base comprising one of a first sub-base assembly and a second sub-base assembly, the first sub-base being adapted for connection to the at least one remote temperature sensor via at least one wire lead, the second sub-base assembly having a receiver adapted for wireless communication with the at least one remote temperature sensor, the main unit being releasably connectable to the sub-base in a manner so that when the main unit is connected to the sub-base the main unit is adapted to receive from the sub-base said information from the at least one remote temperature sensor regardless of whether the sub-base constitutes the first sub-base assembly or the second sub-base assembly.
