Controllers and methods for controlling operation of a climate control appliance for heating and/or cooling a space are provided. One example controller includes a memory for storing at least one temperature offset and a processor coupled to the memory. The processor is configured to receive the reduced operation request from at least one of a utility provider and a user of the controller, to receive a sensed temperature from at least one sensor disposed within the space, and to determine an artificial temperature based on the sensed temperature and the at least one temperature offset associated with the reduced operation request. The processor is configured to, in response to the reduced operation request, operate the climate control appliance based on a comparison of the set-point temperature and artificial temperature during a reduced operation interval, to thereby reduce operation of the climate control appliance in response to the reduced operation request.

A control system is provided for automatically setting up and controlling a climate control system for a building having one or more zones and one or more thermostats in communication with the associated heating or cooling components of the climate control system. In some embodiments, the climate control system comprises one or more heating or cooling systems which may be controlled by one or more thermostats. In other embodiments, the climate control system comprises a thermostat, a heating and cooling system, one or more remote temperature sensors corresponding to at least some of the one or more zones within the building, and one or more dampers corresponding to at least some of the one or more zones within the building.

System and method for controlling a multi-zone heating or cooling system

The present disclosure describes an HVAC system and means for communication between an integrated system of individual controllers for interactively controlling various components in the HVAC system. Various embodiments of an HVAC system are provided that may comprise at least two controllers that communicate with each other to provide a method of controlling the operation of an HVAC system, based on a communication protocol utilized by each of the various controllers. The communication protocol provides for establishing communication between a sending controller and at least one other controller that is the intended recipient. The communication protocol also provides for monitoring of communication signals by one or more controllers in the system, where the one or more controllers monitor communication signals which are intended for other recipient controllers to thereby listen to information being communicated.

System including interactive controllers for controlling operation of climate control system

A thermostat for controlling a climate control system is provided that comprises a network interface for establishing an internet connection with a website of a remote service provider, and a microprocessor for controlling the operation of a climate control system. The microprocessor is in communication with the network interface for establishing an internet connection and receiving user-specified information from a remote service provider that maintains a user-profile of information requested by the user. The thermostat further comprises a display device responsive to the microprocessor for displaying user-specified information received via the network controller from the remote service provider.

Thermostat capable of displaying received information

A system for communicating across conventional HVAC wiring is provided. The system includes a communication device having a communication module capable of inducing low power, high frequency current signals into a single control wire coupling, for example, a thermostat with a compressor. The communication module includes a power supply module that draws power sufficient to operate the communication module from the existing HVAC wiring, so as to eliminate any need for batteries or external power sources. A second communication module may be coupled to the single control wire. The second communication module operates as a transceiver sending communication signals to, and receiving communication signals from, the communication module. In one embodiment, the communication module is disposed within a building, for example coupled to an electronic thermostat, while the second communication module is disposed outside the building near the compressor. The communication signals are RF modulated signals between 5 and 50 MHz so as to take advantage of and pass across parasitic capacitances found inherent in transformers or other coils disposed within HVAC loads.
