•

use residual cool or heat from the heat exchanger and ready for the next operation.

If operating modes of the indoor unit and outdoor unit are not in accordance, the indoor

•

unit fault indicator flashes after 5s and the indoor unit stops. In that case, just mode

conversion can eliminate the conﬂict. Cooling mode is in accordance with dry or fan mode,

while non modes are in accordance with heating mode.
