Switching from cooling/heating (not available for cooling only units) mode to fan only
mode
When the indoor unit reaches the set temperature, the air conditioner controller automatically stops
the compressor operation and switches to the fan only mode. When the room temperature rises (in
cooling mode) or falls (in heating mode) to a certain level, the compressor is restarted and cooling
or heating operation is resumed.
■ In winter, the outdoor temperature is low, and heating effects may be decreased
• In heating mode, the air-conditioning system absorbs heat from the outdoor air and releases
heat to the indoor side. When the outdoor temperature is low, less heat is released. This is
the principle of heat pump.
• When the outdoor temperature is extremely low, the heating capacity of the air conditioner
decreases, and other heating equipment may need to be added.
■ Mode conflict
All indoor units in the same refrigerant system can only operate in the same mode, such as
cooling, heating or other modes. Setting to a different mode will make conflict and the system
will stop. Make sure all indoor units are running in the same mode.
■ No heating or cooling permissions
For the same air conditioning system, if outdoor unit operates in changeover mode, the wired
controller of VIP indoor unit allows users to select modes supported by the indoor units, while
the wired controllers of other indoor units displays the icon of "
No permission
". In this case,
other indoor units can only operate in the same mode as the VIP indoor unit.
