Drying Mode; Forced Opera�On Func�On; Auto-Restart Func�On; Refrigerant Leakage Detec�On - Roland FAVORITE ON-OFF Series Service Manual

• This mode can be selected with the remote controller.
• In auto mode, the machine selects cooling, hea�ng, or
fan-only mode on the basis of T ( T =T1-Ts).

Hea�ng*: In auto mode, cooling only models run the fan
• AC will run in auto mode in the below cases:
• Pressing the forced auto bu�on.
• If AC is off, it will run in auto mode when the �mer
on func�on is ac�ve.
• A�er se�ng the mode, AC will run in auto mode if
the compressor keeps not running for certain �me.

Drying mode

• The compressor is cycled running with 10 minutes
on and then 5 minutes off. The indoor fan will keep
running at low speed.
• In drying mode, if room temperature is lower than
°C
10 , the compressor will stop and not resume un�l
room temperature exceeds 13
• The evaporator an�-freezing protec�on is the same as
that in cooling mode.
1.9 Forced opera�on func�on
• Forced cooling mode:
The compressor and outdoor fan con�nue to run and
the indoor fan runs at low speed. A�er 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
with a preset temperature of 24°C.
• The unit exits forced opera�on when it receives the
following signals:

1.10 Auto-Restart func�on
• The indoor unit has an auto-restart module that
allows the unit to restart automa�cally. The module
automa�cally stores the current se�ngs (not including
the swing se�ng) and, in the case of a sudden power
failure, will restore those se�ng automa�cally within 3
minutes a�er power returns.
• If the unit was in forced cooling mode, it will run in
this mode for 30 minutes and turn to auto mode with
temperature set to 24°C.
• If there is a power failure while the unit is running, the
compressor starts 3 minutes a�er the unit restarts. If
the unit was already off before the power failure, the
compressor starts 20 seconds a�er the unit restarts.
1.11 Refrigerant Leakage Detec�on
• With this new technology, the display area will show
"EC" when the outdoor unit detects refrigerant
leakage.
• When compressor is ac�ve, the value of the Coil
temperature of evaporator T2 has no change or very
little change.
1.12 8°C Hea�ng(Op�onal)
• In hea�ng mode, the temperature can be set to as low
as 8°C, preven�ng the indoor area from freezing if
unoccupied during severe cold weather.
• When the compressor is off, the indoor fan motor is
off.
1.13 Self clean(Op�onal)
• If you press "Self Clean" when the unit is in cooling or
drying mode:
• For cooling models, the indoor unit will run in low
fan mode for a certain �me, then ceases opera�on.
• For heat pump models, the indoor unit will run in
fan-only mode, then low heat, and finally in fan-
only mode.
• Self Clean keeps the indoor unit dry and prevents
mold growth.
1.14 Follow me(Op�onal)
• If you press "Follow Me" on the remote, the indoor
unit will beep. This indicates the follow me func�on is
ac�ve.
• Once ac�ve, the remote control will send a signal
every 3 minutes, with no beeps. The unit automa�cally
sets the temperature according to the measurements
from the remote control.
