Can a single high wall unit heat multiple rooms in the house?
What is Auto Defrost Cycle?
Defrost mode is needed as any ice build-up on the outside heat coil will reduce the airflow across it, effecting efficiency and operation of the heat pump.
When the heat pump goes to defrost mode, you’ll notice the indoor unit will stop heating, the indoor fan will stop or slow right down, the indoor louvers may change position and depending on the model there may be a blinking light on the indoor unit. At the same time the outdoor unit fan may stop running, though the outdoor compressor will continue to run.
NOTE: It is important not to turn off the unit or change any settings on the remote before the defrost cycle has ended; if the unit is restarted prematurely it will resume the cycle and cause delays in completing the defrost function.
