Abstract
A thermostat and method for controlling the overshoot and undershoot of the temperature in a zone that are caused by an air conditioning system responsive to a change in the setpoint of the thermostat is disclosed. The thermostat includes a sensor for detecting the temperature in the zone and being adapted to generate a signal representative of the temperature. A processor for controlling the air conditioning system is communicatively coupled to the sensor and receives the signal representative of the temperature of the zone therefrom. A setpoint input device for changing the setpoint of the thermostat is communicatively coupled to the processor and is adapted to provide a signal representative of the changed setpoint to the processor. The processor controls the air conditioning system in a static condition mode during normal operations and switches the air conditioning system to a full on mode responsive to a setpoint change. The processor is adapted to generate a time based target temperature curve and to compare the target temperature with the temperature in the zone at certain time intervals after the input of the setpoint change. The air conditioning system is switched by the processor from the full on mode of operation to the static condition mode of operation when the sensed temperature in the zone equals the temperature of the target temperature curve.
