摘要

A thermostat may include a processing system, a plurality of HVAC connectors configured to receive a corresponding plurality of HVAC control wires, and a connection sensing circuit coupled to the plurality of HVAC connectors and configured to provide an indication to the processing system of whether a wire is inserted for each of the plurality of HVAC connectors. The processing system may be configured to receive an indication from the connection sensing circuit when an HVAC connector in the plurality of HVAC connectors has a wire inserted therein, the HVAC connector being associated with a plurality of possible HVAC functions. The processing system may also be configured to display the plurality of possible HVAC functions on a user interface, to receive input selecting one of the possible HVAC functions for the HVAC connector, and to operate the selected HVAC function through the HVAC connector.
