CONTROLLER AND METHOD FOR MULTI-ZONE AIR HEATING AND COOLING SYSTEM WITH MOTORIZED VENTS

摘要

A method of controlling a zoned, building air heating, cooling or air conditioning system to control the temperature environment of the individual zones without the use of on-demand heating and cooling sources that consume energy includes collecting data from a plurality of zone temperature sensors; monitoring the temperature sensor data in substantially real-time; generating a trigger signal when zone temperature sensor data is different from predefined zone temperature sensor threshold values; ranking the plurality of temperature-controlled zones based at least on the difference between the real-time zone temperature and the predefined zone temperature sensor threshold value; and adjusting the opening and closing of a plurality of motorized air ventilation ports in the zones according to the rankings of the zones, and activating a fan that moves air between the zones that have open ventilation ports, when the trigger signal is present.
