A thermostat is provided that comprises a touch-sensitive transparent membrane adapted to be affixed over a display, where the transparent membrane has a plurality of membrane switches. The thermostat comprises a microprocessor in communication with the plurality of membrane switches, and has a memory for storing a program for controlling the operation of the climate control system. The thermostat further comprises a display device responsive to the microprocessor for displaying a first screen having at least a first user-interface icon associated with at least one membrane switch, where in response to the user touching the membrane switch associated with the first user-interface icon the display device displays a second screen having at least a run user-interface icon and a schedule user-interface icon.

Thermostat with touch membrane feature

A climate control system having two or more stages of cooling operation or heating operation is provided for supplying conditioned air to a plurality of zones within a space, where the climate control system comprises a plurality of controllable zone dampers for controlling the supply of conditioned air to each of the plurality of zones, and a plurality of zone temperature sensors for periodically sensing temperature at preset intervals and transmitting sensed temperature information when the temperature of the zone has changed by more than a predetermined amount. The climate control system further comprises a thermostat that is adapted to initiate operation of the circulating air blower and the cooling system at less than full capacity when at least one zone temperature sensor transmits a sensed temperature that differs from the set point temperature by more than a specific amount, wherein the thermostat switches the circulating air blower and cooling system to full capacity operation when either the cooling system has operated at less than full capacity for more than a predetermined time or when more than a predetermined number of zone temperature sensors transmit sensed temperatures that differ from the set point temperature by more than a specific amount.
