In exemplary embodiments, HVAC communication bus decoders and corresponding methods are disclosed. In an exemplary embodiment, an HVAC communication bus decoder includes a control circuit having an input for coupling to an HVAC communication bus and one or more relays each having an output for coupling to a legacy HVAC system monitoring device. The control circuit is configured to read one or more messages transmitted on the HVAC communication bus, decode the one or more messages to determine a desired mode of operation called for by a thermostat connected to the HVAC communication bus, and energize at least one of the one or more relays to emulate a corresponding legacy HVAC signal representing the mode of operation called for by the thermostat to be provided to the legacy HVAC monitoring device.

HVAC communication bus decoders and corresponding methods

A thermostat is provided that receives one or more inputs from at least one heating system of a climate control system, and initiates an appropriate action in response to the input. The thermostat can turn off a heat pump providing substandard heat and responsively turn on a fuel-fired auxiliary furnace. The thermostat may discontinue further operation of the auxiliary furnace upon receiving an operating error signal associated with the auxiliary furnace, and responsively turn on the heat pump to provide for continued heating. The thermostat may also discontinue operation of the fuel-fired furnace and turn on a circulating fan in response to an input signal indicating a furnace high-temperature or a carbon monoxide presence.

Climate control system including responsive controllers

A system for controlling the operation of a heating or cooling system includes a system controller, a memory in which system parameter information relating to the heating or cooling system is stored, and a communication device through which the system controller is configured to transmit and receive signals to/from at least one component controller. The system controller is configured to receive via the communication device a data signal from the at least one component controller that includes information relating to operational parameters for at least one system component installed in the heating and cooling system. The system controller is configured to store in the memory the received operational parameters corresponding to the at least one system component. The stored operational parameters may be retrievable for communication to a replacement component controller in the event that the at least one component controller is replaced.

Universal apparatus and method for configurably controlling a heating or cooling system

An interactive system for controlling the operation of an HVAC system is provided that comprises a thermostat for initiating the operation of the HVAC system in either a full capacity mode of operation or at least one reduced capacity mode of operation, and a controller for an outside condenser unit having a condenser fan motor and a compressor motor, the controller being capable of operating the compressor in a full capacity mode and at least one reduced capacity mode. The system also comprises a controller for an indoor blower unit having a blower fan motor, the controller being capable of operating the blower fan motor in a full capacity mode and at least one reduced capacity mode. The system further includes a communication means for transmitting information between the outside condenser unit controller and at least the indoor blower controller, where the information relates to the operation of the indoor blower and the outdoor condenser unit. The indoor blower controller responsively controls the operation of the blower fan motor in a full capacity mode or a reduced capacity mode based on the information received from the outdoor unit controller, and the outdoor unit controller responsively controls the operation of the compressor in a full capacity mode or a reduced capacity mode based on the information received from the indoor blower controller.

Interactive control system for an HVAC system

A system controller is provided that includes a communication network for transmitting and receiving information from an installed blower motor controller, and a removable memory device connected to the system controller. The removable memory device includes stored system parameter information related to a particular heating or cooling system, which information includes at least motor related parameters related to one or more types of blower motors. The system controller further includes a processor that receives, via the communication network, identifying information from the blower motor controller that identifies the type of blower motor that is installed. The processor is configured to retrieve motor related parameters corresponding to the specific identified blower motor from the memory device, and to send the corresponding motor related parameters to the blower motor controller.
