minutes by turns at 60Hz.

6. FAN mode control

The compressor and the outdoor motor will stop running, indoor motor can be set at high/med/low

speed, the fan blade can swing or stay at one position. In this mode, you can set the TIMER and

SLEEP function.

7. HEAT mode control

7.1 4-way valve control: in heating mode, compressor startup----4-way valve being electrified 10

seconds ahead; compressor running----4-way valve retains original state; compressor

shutoff----4-way valve being powered off 2 minutes and 50 seconds later (except for defrosting,

4-way valve being electrified 5 seconds ahead, and being powered off 55 seconds later).

7.2 In heating mode, for everytime the compressor startup (thermostat ON), within 6 minutes, the

4-way valve will not be limited by the temperature sensor, but for the set temperature change,

shutoff signal and the protection, the compressor can stop immediately without 6-minute limitation.

7.3 Tı1 compressor running, indoor motor runs at anti-cold air mode;

Tİ-1 compressor stops, indoor motor runs at blowing remaining heat mode;

-1<T<1 compressor retains original state

7.4 Overheat protection (for the unit with outdoor PCB, the outdoor motor is controlled by outdoor

unit, but the compressor is still controlled by indoor unit, and their temperature points will not be

accordant completely)

In heating mode, compressor has started up and indoor motor has run for over 30 seconds, if indoor

coil temperature Tg>60ć, outdoor motor will stop; if Tg<56ć, and outdoor motor has stop for 45s,

outdoor motor will run again; if Tg>73ć, the compressor will stop and indoor motor will run

according to the thermostat state. After the compressor stops for 3 minutes and Tg reduces to 48ć,

the unit will resume to heating mode, and the compressor and the outdoor motor will run again.

7.5 Temperature cutoff protection

In heating mode (besides the defrosting), the unit will check indoor coil temperature every time the

compressor has run for 1 minutes, when indoor coil temperature Tg˘Tr-5, the unit will stop and 3

minutes later restart up; if the temperature cutoff occurs for 3 times continuously, the unit will stop

and alarm.

7.6 Anti-cold air function in heating mode

After entering heating mode, or last defrosting is over, the compressor will start up, if Tg˘28ć,

indoor motor will stop; if 38ć!Tgı28ć, indoor motor will run at low speed; if Tgı38ć or the

compressor has run for over 4 minutes, indoor motor will run at the set speed; once the motor has

started up, it will not stop because of Tg reduction.

7.7 Blowing remaining heat function

In heating mode, the thermostat is OFF, the compressor stops, indoor motor will run at low speed

until Tg˘28ć and has run for 50 seconds at least.

7.8 Note: in heating mode, “the compressor stops----indoor motor delays to stop” adjust if the pipe

blows remaining heat; “the compressor startup----indoor motor delays to start up” adjust if the pipe

is anti-cold air; in other conditions, the compressor and the indoor motor are allowable not to be in

company. In cooling mode, the motor will run according to the control, not together with the

compressor.

7.9 Defrosting function in heating mode

In defrosting and when the compressor resumes to run for 3 minutes after defrosting is over, the

unit will not adjust the sensor failure.

Manual defrost: In heating mode, the set temperature 30ć and in high speed, in 5 seconds, press
