4.9.3 Displaying setting of freeze protection error code
Under debugging state, press Mode button to adjust to “02” in temperature displaying zone. Timer
zone displays setting state and press ▲ or ▼ button to adjust. There are 2 selections:
(1) Displayed (LCD displays 01)
(2) Not displayed (LCD displays 02)
It is defaulted to be not displayed for export unit and be displayed for domestic unit.
4.9.4 Setting refrigerant lacking protection function
Under debugging state, press Mode button to adjust to “04” in temperature displaying zone. Timer
zone displays setting state and press ▲ or ▼ button to adjust. There are 2 selections:
(1) With refrigerant lacking protection function (LCD displays 01)
(2) Without refrigerant lacking protection function (LCD displays 02)
4.9.5 Selecting blowing residual heating of indoor unit
Under debugging state, press Mode button to adjust to “05” in temperature displaying zone. Timer
zone displays setting state and press ▲ or ▼ button to adjust. There are 2 selections:
(1) Mode 1 (LCD displays 00)
(2) Mode 2 (LCD displays 01)
Note:
Blowing residual heating of indoor unit
Mode 1: Unit stops when reaching temperature point and indoor fan motor does not stop in cooling
mode; after unit stops when reaching temperature point in heating mode, duct type unit and floor ceiling
unit blow residual heat for 60s and then stop indoor unit, while cassette type unit always operates in low fan
speed and blows residual heat for 60s when there is malfunction.
Mode 2: After unit stops when reaching temperature point, the indoor fan motor stops operation with a
10s delay no matter in cooling mode or in heating mode.
4.9.6 Mode selecting of compressor electric heating belt
Under debugging state, press Mode button to adjust to “06” in temperature displaying zone. Timer
zone displays setting state and press ▲ or ▼ button to adjust. There are 2 selections:
(1) Mode 1 (LCD displays 00)
(2) Mode 2 (LCD displays 01)
Notes:
① Mode 1: Compressor electric heating belt starts when outdoor ambient temperature is below
35
℃
(95
℉
) and stops when outdoor ambient temperature is above 37
℃
(99
℉
). When
outdoor ambient temperature is within 35
℃
(95
℉
)~ 37
℃
(99
℉
), the belt will keep its
previous operation state.
② Mode 2: Compressor electric heating belt starts when outdoor ambient temperature is below
-2 (28
℉
) and stops when outdoor ambient temperature is above 0
℃
(32
℉
). When outdoor
ambient temperature is within -2
℃
(28
℉
)~0
℃
(32
℉
), the belt will keep its previous
