5 PIPING DIAGRAM Schematic Diagram of MULTI COMBI M The outdoor and indoor units start to work once the power is switched on. During the cooling operation, the low temperature, low pressure refrigerant gas from the heat exchanger of each indoor unit gets together and then is taken into the compressor to be compressed into high temperature, high pressure gas, which will soon go to the heat exchanger of the outdoor unit to exchange heat with the outdoor air and then is turned into refrigerant liquid.

2 MAIN LOGIC 2.1 Control Function of Outdoor Unit 2.1.1 Cooling Mode a. Cooling conditions and process: If the compressor is in stop status and start the unit for cooling operation, when one of the indoor units reaches the cooling operation condition, the unit start cooling operation; in this case, the electronic expansion valve, the outdoor fan and the compressor start operation. b. Stop in cooling operation a) Compressor stops The compressor stops gradually, the outdoor fan stops after 1min.
The indoor unit displays “H1” c) Oil-returned finished condition in heating mode The duration reaches 5min 2.1.4 Fan Mode The compressor, the outdoor fan and the 4-way valve are closed; temperature setting range is 16 ～ 30℃ . 2.2 Protection Function 2.2.1 Mode Conflict Protection of indoor unit When the setting mode is different of different indoor unit, the unit runs in below status: a.
b) On condition that a low pressure protection error occurs and the whole unit has stopped for more than three minutes and it is detected continuously for six seconds that the low pressure protection switch is closed, then this error can be eliminated. However, if the low pressure protection occurs twice in one hour, then it has to eliminate the error by powering the outdoor unit again. 2.2.
b) The defrosting symbol “H1” will be displayed when the defrosting signal is received from the outdoor unit. e. AUTO Mode a) When the ambient temperature is higher than 25℃ , the unit will run as the COOL mode. b) For the cooling and heating unit, if the ambient temperature is or lower than2 0℃ (72 ℉ ), the unit will run as the HEAT mode.
