• If any one of the following conditions is satisfied,
defrosting ends and the machine switches to normal
heating mode:
• T3 rises above TCDE1°C.
• T3 maintained above TCDE2°C for 80 seconds.
• Unit runs for 15 minutes consecutively in defrosting
mode.
• If T4 is lower than or equal to -22°C and compressor
running time is more than TIMING_DEFROST_TIME,
if any one of the following conditions is satisfied,
defrosting ends and the machine switches to normal
heating mode:
• Unit runs for 10 minutes consecutively in defrosting
mode.
• T3 rises above 10°C.
For some models:
• If T3 is lower than 3°C and compressor running time
is more than 120 minutes, at this time, if T3 is lower
than TCDI1+4°C(39.2°F) for 3 minutes, the unit enters
defrosting mode.
For some models:
• If any one of the following conditions is satisfied, the
unit enters defrosting mode
• If T3 or T4 is lower than -3°C for 30 seconds,Ts-T1
is lower than 5°C and compressor running time is
more than EE_TIME_DEFROST7.
• If T3 or T4 is lower than -3°C for 30 seconds and
compressor running time is more than EE_TIME_
DEFROST7+30.
• If any one of the following conditions is satisfied,
defrosting ends and the machine switches to normal
heating mode:
• T3 rises above TCDE1+4°C.
• T3 maintained above TCDE2+4°C for 80 seconds.
• Unit runs for 15 minutes consecutively in defrosting
mode.
1.6.5 Evaporator Temperature Protection
• Off: Compressor stops.
• Decrease: Decrease the running frequency to the lower
level per 20 seconds.
• Hold: Keep the current frequency.
• Resume: No limitation for frequency.
1.7 Auto-mode
• This mode can be selected with the remote controller
and the setting temperature can be changed between
16°C~30°C.
• In auto mode, the machine selects cooling, heating,
auto-drying or fan-only mode on the basis of T1,Ts, T4
and relative humidity.
• If the setting temperature is modified, the machine
selects a new running function.
1.8 Drying mode
• In drying mode, AC operates the same as auto fan in
cooling mode.
• All protections are activated and operate the same as
they do that in cooling mode.
• Low Room Temperature Protection
If the room temperature is lower than 10°C, the
compressor ceases operations and does not resume until
room temperature exceeds 12°C.
1.9 Forced operation function
• Forced cooling mode:
The compressor and outdoor fan continue to run(fixed at
rated frequency), and the indoor fan runs at rated speed.
After running for 30 minutes, the AC will switch to auto
mode with a preset temperature of 24°C.
• Forced auto mode:
Forced auto mode operates the same as normal auto mode
