Abstract: A thermostat compatible with single-HVAC- and dual-HVAC-transformer systems may include a first power return wire connector, a second power return wire connector, and a user-moveable mechanical element that physically blocks wire insertion into the first wire connector when in a first position and physically allows wire insertion into the first wire connector when in a second position. The thermostat may also include a switching circuit that may be in a first configuration when the mechanical element is in the first position, and in a second configuration when the mechanical element is in the second position. The first wire connector may be electrically coupled to the second wire connector in the first configuration, and first wire connector may be electrically isolated from the second wire connector in the second configuration to promote foolproofing against undesired isolation of the first and second wire connectors.
