Title:
CONTROLLER FOR TEMPERATURE REGULATING SYSTEM AND METHOD THEREOF
Document Type and Number:
Japanese Patent JPS60200037
Kind Code:
A
Abstract:
A control for a multi-stage heating and cooling system used to temperature conditioning a comfort zone. The control includes a microprocessor responsive to a temperature sensor installed in the comfort zone. Heating and cooling setpoints and a lookup table including a plurality of ranges for deviation of the comfort zone from the setpoint temperature and associated limits for the rate of change of the comfort zone temperature used in determining specific staging control actions are stored in solid state memory accessed by the microprocessor. The stages of temperature conditioning are controlled as a function of both the deviation of the zone temperature from the heating or cooling setpoint (depending on the system operating mode), and the rate of change of zone temperature. The mode of operation, i.e., heating or cooling, is determined by the relative values of the zone temperature and the heating and cooling setpoint.
