CONTROL PANEL OPERATION
Control Panel
Operation
The control panel keypad will look like the following Fig. 1. For some models with REMOTE
SIGNAL RECEPTOR, the unit can be controlled by the control panel alone or by the remote.
POWER
Press the POWER button to turn the unit
on or off. When the unit is on, the power
indicator light will be green. When the unit
is off, the light will go out.
MODE
Push this button to cycle through the
modes from COOL-HEAT-FAN-COOL.The
indicator light beside the “MODE” option will
illuminate, identifying the mode selected.
• COOL: The range of set temperature is 62°
F-86°F (17°C-30°C). Cooling begins
au
tomatically when the room temperature
is above the set point,and stops when the
ro
om temperature is 4°F (2°C) below the
se
t point. But the compressor will run 5
minutes at least in COOL mode before
stopping. The fan runs in continuous mode.
• HEAT: The range of set temperature is
62°F-84°F (17°C-29°C). For heat pump
models, the unit can alternate to run
between the reverse cycle heat mode and
electric mode according to the difference
between the setting temperature and the
room temperature. The fan motor cycles
on and off with the compressor and
electric heater.
NOTES
The reverse cycle and electric
heater cannot be ran at the same
time. In following cases, it is
normal that the reverse cycle does
not operate.
1. When the outdoor temperatrue is
lower than 4°C/40°F or the room
temperature falls to 4.5°C/8°F
below the set point temperature.
2. There is a 3-minute minimum
compressor run time at any
setting to prevent short cycling.
The indoor fan motors starts
before the compressor and stops
after the compressor cycles off.
3. Push the S1 on the DIP SWITCHES
to UP (ON) position.
4. When frost builds up to the
evaporator coils, the unit will
defrost automatically and the
compressor will cycle off.
• FAN: Fan operation only without
heating and cooling.
