Abstract: A system for calibrating inductance at a motor comprises the motor, a motor drive circuit, and a processor operably coupled to the motor. The processor determines inductance map data that comprises a set of inductance values associated with a set of current values. The processor determines that the motor is in operation. In response, the processor determines current values with which the motor is being operated. The processor determines inductance values associated with the determined current values. The processor determines reference current values at the motor based on the determined inductance values. The processor also determines a speed and torque associated with the motor based at least on the determined inductance values. The processor then controls the operation of the motor based on the determined reference currents, the speed, and the torque.

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.

Abstract: This disclosure is directed to an electronic thermostat for a heating, ventilation, and air conditioning (HVAC) system that includes an electronic level feature and leveling register that allow the thermostat housing to be rotated about a mounting wall plate to place the thermostat housing in a leveled position. In one aspect, the thermostat includes at least one accelerometer. Other systems and methods are disclosed.

Abstract: A system and method are disclosed that provide for a dual processor architecture in a furnace or HVAC controller. One processor can control non-safety-critical components and is operable to receive software updates. The other processor can control safety-critical components and is not capable of being updated. Safety-critical components can comprise a flame sensor, gas valve and an igniter.
