Title:
SYSTEM AND METHOD FOR CONTROLLING AN HVAC UNIT BASED ON THERMOSTAT SIGNALS
Document Type and Number:
WIPO Patent Application WO/2016/136123
Kind Code:
A1
Abstract:
A method is provided for controlling an HVAC unit, including: receiving signals from a thermostat; setting a mode of the HVAC unit to a heating or cooling mode when an appropriate signal is enabled; setting a capacity of the HVAC unit to a set capacity based on the input signals; calculating a heating/cooling change rate based on temperature data received from the HVAC unit; comparing the heating/cooling change rate with a threshold; maintaining the HVAC unit at the set capacity percentage if the heating/cooling change rate is equal to the threshold; lowering the current capacity by a first cooling increment, to a minimum of 0%, if the heating/cooling change rate is above the threshold; and raising the current capacity by a second cooling increment, to a maximum of 100%, if the heating/cooling change rate is below the threshold.
