8. Electric control function:
8.1 Indoor unit
8.1.1 Cooling operation
8.1.1.1 Anti-freezed function of evaporator
a. Be valid in cooling or defrost mode; be invalid in trial or heating mode.
b. If the evaporator temperature is below -1 ℃ for 5 minutes, ourdoor fan and
compressor will stop; if the evaporator temperature goes up to over 7℃ and the
compressor has stopped for over 3 minutes, the unit will resume.
c. When the evaporator anti-freezed function works, the indoor motor and the thermostor
will work together.
d. Compressor control
Being powered on for the first time is without the 3-minutes protection. If the compressor
stops, it can start up 3 minutes later.
e. Remote controller control
The adjustment of set temperature and the remote controller shutoff will not be limited by
6-minute control, you can shut off the unit right now.
8.1.1.2 Dehumidification operation
*temperature range：16～30℃
*temperature control precision：±1℃
*Control characteristic:Tr=room temperature; Ts=set temperature
Tr>Ts+2℃，the compressor and the outdoor motor will go on running, the indoor
motor will run at the set speed.
T<Tr<Ts+2℃，the compressor and the outdoor motor will run for 10 minutes and then
stop for 6 minutes; the indoor motor will stop within 3 minutes after compressor stops, in
the other time, it is at low speed.
In the cross section, there is tolerance of ±1℃.
*Against the current impulse: outdoor motor will run 2 seconds later after compressor
starts up.
*Flap position control:
Set the swing flap position due to the actual requirement, press “SWING” to stop swing;
press again, flap can swing freely. Powered on for the first time, the flap will not swing.
*Ice-proof protection(invalid for trial and heating mode):
Avoid the evaporator being iced in cooling or dehumification mode. When compressor
runs for over 5 minutes and indoor coil temperature is not more than -1℃, the compressor
will stop. When indoor coil temperature goes up to over 7℃, and the compressor has
stopped for over 3 minutes，the compressor will re-start up.
*TIMER ON/OFF function
*SLEEP function
8.1.1.3 Heating operation
The compensation temperature:4.67℃
Control tolerance: ±1℃
*Temperature control range:16～30℃
*Temperature control precision:±1℃
*Control characteristic:
When Tr≤Ts for the first time, the compressor, 4-way valve and outdoor motor will run;
indoor motor will run at anti-cold air mode, after the compressor starts up, the
