Abstract: An HVAC system controller is provided having a first output terminal electrically coupled to at least one component, and a second output terminal electrically coupled to the at least one component. A processing device controls the first output terminal and the second output terminal. If the first output terminal fails, the processing device changes a state of at least one of the first output terminal and the second output terminal.

Abstract: A forced air conditioning system includes supply and return air plenum, an air treatment device, first and second air return dampers, first and second sensors, and a controller. The plenums communicate with first and second rooms and the treatment device is adapted to condition air when activated and not condition air when deactivated. The air return dampers are adapted to isolate the respective first and second rooms when closed. The sensors are located in the respective first and second rooms and are configured to detect a condition of the air. The controller is configured to receive condition signals from the respective sensors, compare the signals to a preprogrammed air condition threshold, and output a command signal to close one of the dampers to substantially equalize the air condition between rooms when the preprogrammed air condition threshold is met, and the air treatment device is deactivated.

Abstract: A method of controlling power applications for a power transformer in a heating ventilation and cooling system (HVAC). The method includes measuring a voltage output of a transformer, the transformer configured to supply control power to a component of the HVAC system, determining a loading of the transformer; prioritizing a loading of the transformer; and applying the prioritization to mitigate loading constraints associated with the transformer.

Abstract: A climate controller includes a housing defining an interior cavity and having an outer surface and an inner surface. Also included is a circuit board disposed within the interior cavity of the housing. Further included is a sensor mounting assembly that includes a mounting retainer operatively coupled to the inner surface of the housing. The sensor mounting assembly also includes a circuit connector in fixed engagement with the mounting retainer and electrically connected to the circuit board. The sensor mounting assembly further includes a sensor mounted to the circuit connector.

Abstract: A wall mountable user interface unit (20) has first (22) and second (24) sections. The first section (22) has: a body (32) mountable to a wall and having first features (50A, 50B); power relays (104); and a first interface (110) for two-way communication with the second section including a first electrical connector (44). The second section (24) is mountable to and demountable from the first section and has: a body (34) having second features (70A, 70B) for holding the second section to the first section in a mounted condition; a second interface (224) for two-way communication with the first section and including a second electrical connector (46) carried by the second section body and mated to the first electrical connector in the mounted condition; a processor (200); and a display (26).

Abstract: An air conditioning system for an occupiable structure having a plurality of regions includes a plurality of air condition sensors, an air conditioning unit, and a programmable controller. The air condition sensor assemblies are each located in a respective region of the plurality of regions. The air conditioning unit is adapted to condition air in the occupiable structure. The controller is configured to receive a plurality of condition signals from each one of the plurality of air condition sensor assemblies and output an activate command that facilitates activating the air conditioning unit. The activate command is based on any one of the condition signals and a preprogrammed condition threshold. Each one of the condition signals is associated with a respective programmed time interval of a plurality of programmed time intervals.

Abstract: A component of an HVAC system includes a controller; a communications module in communication with the controller, the communications module including: a modulator/demodulator configured to encode and decode data in a modulated waveform on a communications interface.
