    摘要: A controller of an indoor unit included in an air-conditioning system includes a power applied time error determination unit that, when a communication error occurs in communication with an outdoor unit, determines whether or not the communication error is a power applied time error peculiar to a power applied time when electric power is fed from a commercial power supply to the outdoor unit, a connection establishment error determination unit that, when the power applied time error determination unit determines that the communication error is not the power applied time error, determines whether or not the communication error is a connection establishment error that occurs at a time of establishing a connection with the outdoor unit, to detect power failure in the outdoor unit, and a fan control unit that, when the connection establishment error determination unit determines that the communication error is the connection establishment error, drives a fan by electric power fed from an emergency power supply.

    摘要: A method is provided for controlling an HVAC unit, including: receiving input signals from a thermostat; setting a mode of the HVAC unit to a heating mode when a heating signal is enabled, or to a cooling mode when a cooling 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.
