Abstract: A thermostat includes a present lifestyle activity comfort level corresponding to each of at least three thermostat user interface buttons. The thermostat user interface buttons can be preset using a “radio preset” style of setting. A method of selecting a comfort level includes the step of presetting user operable buttons labeled with a lifestyle activity comfort choice to a comfort level choice using a “radio preset” style of presetting. Also, a thermostat for controlling the comfort level in a building space includes a receiver coupled to a microcomputer, wherein the receiver reacts responsively to a signal indicating the presence of a person in the building space such that on detection of the presence of the person by the receiver, the thermostat sets a comfort level preferred by that person according to a preset comfort level.

Abstract: 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.
