Control room temperature with the air conditioner

With the heating mode, the air conditioner can make your space warm. If you turn on the heating mode for the first 3 to 5 minutes, the fan may not work so that cold air does not flow until the air conditioner warms up. If the air conditioner heats insufficiently, use an additional heating appliance in combination with the air conditioner.

When the outdoor temperature is low and the humidity is high, frost may develop on the outdoor heat exchanger, which may decrease the heating efficiency. When these conditions are present while Heat mode is on, the air conditioner runs the Defrost function for 5 to 12 minutes to remove frost from the outdoor heat exchanger.

When the Defrost function is on, the df indicator appears on the indoor unit display, steam is produced on the outdoor unit. Then, the air conditioner stops running to prevent cold air from coming out of the indoor unit.
