Evaporator Coil Temperature Protection
Fig. 29 — Evaporator Coil Temperature Protection
When the evaporator temperature is higher than the setting protection
value, the compressor stops.
AUTO Mode
AUTO
mode can be selected with the remote controller and the
setting temperature can be changed between 60.0°F~86°F
(16°C~30°C).
In
the AUTO
mode, the unit chooses either
COOLING
,
HEATING
or the
FAN-ONLY
mode accT2, T4 and relative humidity.
Fig. 30 — AUTO Mode
Heating*:
COOLING ONLY
models run at fan speed. The indoor
fan runs in the
AUTO
fan speed for the relevant mode. The louver
operates the same as in the relevant mode.
If the unit switches mode between
HEATING
and
COOLING
, the
compressor repeatedly stops for a certain time and then chooses the
mode according to T1-Ts. If the setting temperature is modified, the
unit selects a running function again.
DRYING mode
The indoor fan speed is fixed at breeze and can not be changed. The
louver angle is the same as in the
COOLING
mode.
Low Indoor Room Temperature Protection
In the
DRYING
mode, if the room temperature is lower than 50°F
(10°C), the compressor stops and does not resume until the room
temperature exceeds 53.6°F (12°C).
Evaporator anti-freezing protection, condenser high temperature
protection and outdoor unit frequency limit are active and are the
same as that in the
COOLING
mode. The outdoor fan operates the
same as in
COOLING
mode.
FORCED OPERATION Function
Enter FORCED OPERATION function:
When the machine is off, press
TOUCH
to engage the
Forced
Auto
Mode
. Press
TOUCH
again, within 5 seconds, to engage the
FORCED
COOLING
mode. In
FORCED
AUTO
,
FORCED
COOLING
or any other operation mode, press
TOUCH
to turn off
the unit.
In the
FORCED
OPERATION
mode, all general protections and the
remote controller are available.
Operation Rules:
FORCED COOLING
mode:
The compressor runs at the F2 frequency and the indoor fan runs as a
breeze. After running for 30 minutes, the unit enters the
AUTO
mode
at a 75.2°F (24°C) setting temperature.
FORCED AUTO mode:
The
FORCED AUTO
mode is the same as the normal
AUTO
mode
with a 75.2°F (24°C) setting temperature.
AUTO-RESTART function
The indoor unit is equipped with an
AUTO-RESTART
function,
which is carried out through an auto-restart module. In case of a
sudden power failure, the module memorizes the setting conditions
before the power failure. The unit resumes the previous operation
setting (not including the swing function) automatically 3 minutes
after the power returns.
If the memorization condition is the
FORCED COOLING
mode, the
unit runs in the
COOLING
mode for 30 minutes and enters the
AUTO
mode as 75.2°F (24°C) setting temp.
If the air conditioner turns off before the unit powers off and the air
conditioner is required to restart immediately, the compressor delays
for 1 minute when the power is on. Under other conditions, the
compressor has a 3 minute delay when it restarts.
Refrigerant Leakage Detection
With this new technology, the display area displays
EC
when the
outdoor unit detects a refrigerant leak.
46°F (8°C) Heating
When the compressor is running, the indoor fan motor runs without
the anti-cold air function. When the compressor is off, the indoor fan
motor is off.
