Beschreibung
Zusammenfassung:	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. 提供了种用于控制HVAC单元的方法，该方法包括：从恒温器接收信号；当适当的信号被启用时，将HVAC单元的模式设置为制热或制冷模式；基于输入信号将HVAC单元的能力设置为设置的能力；基于从HVAC单元接收的温度数据来计算制热/制冷变化速率；将制热/制冷变化速率与阈值进行比较；如果制热/制冷变化速率等于阈值，则使HVAC单元保持在设置的能力百分比；如果制热/制冷变化速
