Electric control function (
For outdoor unit
)
A.
Indoor unit
A
.1 Cooling operation
A
.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.

*Control characteristic:
Tr=room temperature; Ts=set temperature

the compressor and the outdoor motor will go on running, the indoor
motor will run at the set speed.
z
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.
zF
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
10
℃
, and the compressor has
stopped for over
9
minutes
，
the compressor will re-start up.
