Page 24: Electronic Function
8. Electronic Control Principle of Large Cooling Capacity Split Model A/C Fan only mode Fan speed is high/mid/low/ Auto Cooling mode The 4-way valve is closed at cooling mode. The action of the compressor and the outdoor fan: T: Room temp. Ts: Setting temp. - Page 25 8.4.1 Generally, the 4-way valve is open in heating mode, but it is closed in defrosting mode. 8.4.2 Generally, the outdoor fan is turned off with the on-off action of compressor in heating mode, except for the defrosting mode or the end of defrost. 8.4.3 Action conditions of compressor at heating mode: compressor must run for 4 minutes after starting and then judge temperature.

- Page 27 8.8.1.3 During the start-up and operation, all of the following protecting functions work: 3minutes start-up delay protection, overload protection, outdoor protection, evaporator Protection against low temperature. If any of the protection functions, the comparative protecting action is executed. The forced cooling mode is closed by one touch on the button, meanwhile the operation light is off, the buzzer buzzes lasts for 1 seconds, then A/C turns to be closedown status.
