Abstract: The provided systems and methods may compare an initial terminal voltage of a battery to a first initial voltage threshold and a second initial voltage threshold. The provided systems and methods may determine whether the initial terminal voltage of the one or more batteries is lower than the first initial voltage threshold and if the initial terminal voltage of the one or more batteries is greater than the second initial voltage threshold. The provided systems and methods may then confirm that the one or more batteries corresponds to a first battery type if the initial terminal voltage is less than the first initial voltage threshold and confirm that the one or more batteries corresponds to a second battery type if the initial terminal voltage is greater than the second initial voltage threshold.

Abstract: An HVAC thermostat assembly has a wall-plate connector that includes a wall-plate and wire connectors as a whole that allows for a thinner, more aesthetic design. In one instance, the HVAC thermostat includes a display unit with a wall-plate connector recess having a plurality of electrical connector pins extending outward to mate with a wall-plate connector. The wall-plate connector includes a wall plate with incorporated electrical terminals. Other assemblies and systems are disclosed.
