A system and method of configuring HVAC components in an HVAC system including a main system controller in operable communication with at least one auxiliary controller, wherein the main system controller and each of the at least one auxiliary controllers include a near field communication interface. The HVAC system components are configured by placing each of the at least one auxiliary controllers in close proximity to the main system controller, and operating the main system controller to initiate a pairing event.

System and method of configuring HVAC components in an HVAC system

The invention relates to a thermostat including a user interface module. The user interface module has a display, a plurality of user interface buttons, and a first power and communications interface. The thermostat also includes an I/O module, the I/O module electrically coupled to a HVAC plant and the I/O module having a plurality of switches to control the HVAC plant, and a second power and communications interface. The user interface module and the I/O module are communicatively coupled and exchange power via the power and communications interfaces and the thermostat can be mounted and operated in one of two user selectable installations: a stacked configuration comprising a thermostat having the user interface module directly mounted to the I/O module, or a remote configuration comprising a thermostat having the user interface module remotely mounted from the I/O module.

Stackable thermostat

Thermostat

A thermostat includes a display and an illumination device that is configurable to illuminate the display in a partial illumination mode and a full illumination mode. In the partial illumination mode the illumination device generates a light intensity sufficient to review the settings of the thermostat without generating heat of a sufficient amount to disrupt thermostat measurements. The full illuminated condition is actuated upon interaction with the thermostat. Once interaction with the thermostat is completed the illumination device thermostat returns to the partially illuminated condition.

Configurable multi-level thermostat backlighting

A method and apparatus for controlling the operation of an air conditioning system and a plurality of auxiliary devices, with both the air conditioning system and the auxiliary devices being adapted to operate in a setback condition. The auxiliary devices are operated in a setback condition in response to the operation of the setback operation of the air conditioning system such that, generally, the auxiliary devices are operated in a setback condition when the air conditioning system is operating in a non-setback condition and vice versa so as to thereby achieve load balancing. In addition, the auxiliary devices can, at the same time, be operated in the setback mode on the basis of duty cycle.

Balanced utility load management

Control device

A thermostat receives setpoint information from a system in communication with the thermostat. The thermostat is operative to modify any locally entered setpoints by a predefined amount dictated by the setpoint information received from the system in communication with the thermostat. The thermostat is preferably operative to continually display the time remaining during which it will be under the control of the system in communication with the thermostat. This affords an occupant of the room viewing the displayed time with an opportunity to elect to either continue or to override the control by the system in communication with the thermostat at any time.

Communicating thermostat

A device and method for controlling the conditioning of air in the zones of a forced air HVAC system. The device comprises thermostats located in at least two different zones, air ducts and dampers located therein to control the flow of air to the different zones. The microprocessor receives signals from the thermostats corresponding to perceived temperatures in the zones and compares the perceived temperatures to predetermined temperatures and determines a trajectory for each of the zones. The microprocessor in turn sends signals to the dampers corresponding to a positions between fully open and fully closed to control the amount of conditioned air through the ducts such that each of the zones follows the trajectory and reaches the predetermined temperatures at about the same time. The microprocessor further determines system demand and turns the HVAC system on and off in response to the system demand.
