Ŷ Light Control
If set the light is on with remote control, the indicator lamp and dual-8 display the current setting status; if set the
light is off with remote control, turn off the lamp immediately. If there is front panel button or remote control button
operation when setting light off with remote control, the indicator lamp and dual-8 display current setting status,
and turn off the light 5S later. Remote control light button does not controlled by failure display.
Ŷ SWING Motor Control
After the unit is energized, the swing (up and down) motor will make the guide louver circumvolve to position 0;
close the outlet port. After the unit is on, if it does not set swing function, guide louver (up and down) will
circumvolve to position D. Setting swing function when the unit is on, the guide louver swings between L and D.
There are 7 swing statuses for guide louver: position L, position A, position B, position C, position D, swing
between position L and D, stop between any position L and D.
When the unit is off, the guide louver will chose to position 0. The swing action is valid when setting swing order
and indoor fan is running.
Note: When the remote control setting is on position L to B, position A to C, position B to D, the guide louver swings
between position L and D. The angle of energized reset swing off is: 80°; when the unit is off, add 5°to the current
angle then close guide louver. The corresponding angle of position L to D is: 39°-48°-57°-66°-75°.
Ŷ Protection Function
Ɣ Anti-freeze Protection
When the anti-freeze protection is inspected, the compressor stops, fan motor runs with setting fan speed. When
the anti-freeze protection is canceled and reaches to the 3min time-delay, it runs with the original status.
Temperature s e n s o r f ailure ins pe c t i o n
e) Environment temperature sensor is open, short circuit: dual-8 displays F1, the cooling indicator lamp goes out
3S and blinks 1 time, and it will light up 0.5S and go out 0.5S when it is blinking.
f) Indoor pipe temperature sensor is open, short circuit: dual-8 displays F2, the cooling indicator lamp goes out
3S and blinks 2 times, and it will light up 0.5S and go out 0.5S when it is blinking.
g) Outdoor pipe temperature sensor is open, short circuit: dual-8 displays F4, the cooling indicator lamp goes out
3S and blinks 2 times, and it will light up 0.5S and go out 0.5S when it is blinking.
h) The compressor or electric heating pipe stops when the temperature sensor failure and the unit is on, The fan
motor will be deal regarding compressor or electric pipe reach to the temperature point and stops.
ƽ Over current Protection
If the system current is inspected too large for 3min continuously, the fan motor runs with setting conditions, other
load stops; 3min later, the unit runs with the previously status; if over current protection occurs for 6 times
continuously, display error code “E5”, the load stops this time; if block the button except ON/OFF button, it will
remote control the unit to off then on, or turn off with button, or re-energized; the time of over current protection will
zero clearing with remote control, press to turn on or re-energized.
ƽ Over-flow Protection
If the over-flow is detected for 3S, it will enter into over-flow protection. Display error code H8, heating indicator
lamp or over-flow indicator lamp goes out 3S and blinks 8 times.
