Abstract: 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.

Abstract: 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.
