2.5 LOUVER CONTROL
2.5.1 When unit is first turns on, louver will swing with 30 degree automatically.
2.5.2 Use the handset to control the louver to swing or stop at the desired location along the
30 degree range.
Note: To prevent causing damage to the stepper motor, it is not recommended to move the
louver by hand.
2.6 PROTECTION FUNCTIONS
2.6.1 Compressor 3 minutes delay protection
a. The first time the unit is connected to electric power, the compressor will run at once.
b. After compressor stops every time, it must delay 3 minutes before starting again (Except
heating mode and defrost function).
2.6.2 Anti-freeze protection in cooling and dehumidification modes
a. When the sensor determines IPT ≤ -1
℃
, compressor and outdoor fan motor will stop, indoor
unit will maintain its original state.
b. When IPT ≥ 8
℃
, and is in the protection state for 3 minutes, compressor and outdoor fan
motor start again and exit the anti-freeze protection state.
2.6.3 Over heat protection in heating mode
In heating mode:
a. When IPT ≥ 55
℃，
outdoor fan motor will stop.
b. When IPT ≤ 48
℃，
outdoor fan motor start again.
c. When IPT ≥ 64
℃，
compressor and outdoor fan motor will stop.
d. When IPT ≤ 48
℃，
3 minutes later compressor and outdoor fan motor will start again.
In this case, four-way valve is always open and indoor fan motor always runs according to the
setting.
2.6.4 Sensor damage protection
2.6.4.1 When RT sensor is damaged
a. When unit is in cooling, heating or dehumidification mode, and the RT temperature is lower
than -40
℃
or higher than 120
℃，
the sensor is judged to be damaged and the unit will go into
protection mode - compressor will operate for 20 minutes and stop for 5 minutes repeatedly.
b. When unit is in auto mode, and the RT temperature is lower than -40
℃
or higher than 120
℃，
the sensor is judged to be damaged and the unit will go into fan mode.
Note: After the RT sensor is damaged, the green light will flash with 1Hz frequency, or the unit
will display E1 on the panel.
