Abstract:
1. A climate control system having two or more stages of cooling operation for supplying conditioned air to a plurality of zones within a space to be conditioned, the system comprising: a plurality of zone temperature sensors for periodically sensing temperature at preset intervals, and for transmitting sensed temperature information when the temperature of the zone has changed by more than a predetermined amount; a plurality of controllable zone dampers for controlling the supply of conditioned air to each of the plurality of zones in the space; a multi-speed circulating air blower for varying the flow rate of conditioned air to be supplied to the zones; and a thermostat capable of receiving transmitted temperature information from the plurality of zone temperature sensors, where the thermostat responsively initiates the operation of the circulating air blower and 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, and the thermostat responsively initiates the opening of one or more controllable zone dampers corresponding to the at least one zone temperature sensor which transmitted a sensed temperature differing from the set point temperature by more than a specific amount to supply conditioned air to the at least one zone; and wherein the thermostat discontinues the use of temperature information from the at least one zone temperature sensor and displays a system error if the at least one zone temperature sensor does not transmit a significant change in sensed temperature for the at least one zone after a predetermined period of cooling system operation.
