recalculate when compressor run continuely over 5min;
2)Through test the temperature of sensor of Tc & Ta and meet the following condition at
the consecutive 5min:
Tc ≤ C×Ta － α
And C

Should be H when it’s easy to frost,L when it’s hard to frost,M when it’s done.
The restrictment of temperature for anti-frost:
When the data is only C×Ta
－
α≤ 2 ,it’s able to take the frost away.

Anti-frost run
1)The compressor & outdoor motor stop to run after anti-frost start and four way valve
stop to run after 50s;
2)It should be 60Hz for 60s when compressor run again and then run to
85Hz(EEEPROM can adjust);
3)If overflow & exhaust of compressor are available and compressor stop to run as the
protection of current when frost,compressor stop to run for 3min;If compressor stop to run
for 10s because of other protection,compressor stop to run for 10s;If it’still at the time of
anti-frost,it goes on and compressor run as per the rule of compressor operation;
4)Should the time of compressor operation be over 2min,it can quit from anti-frost.

Condition of anti-frost exit
Anti-frost quit automaticly if meet one of the following condition:
1)Temperature of outdoor heat exchanger
≥ 13 at the consecutive 80s
℃
2)The consecutive time of anti-frost ≥ 9min(EEEPROM can adjust)

、
Anti-frost exit
Compressor stop to run and outdoor motor start when compressor stop to run for 50s and
then compressor’s
7. Sleep Control
Sleep function is available at the auto 、 cooling 、 heating mode and indoor motor run at the
lower wind speed at the sleep mode,indicator light work when working frequency meet the
wind speed limitative frequency.
If press to the button of sleep to run for 1h,the certain temperature go up 1 automaticly at
℃
the cooling mode ; If press to the button of sleep to run for 1h,the certain temperature go down
2 automaticly.After run for 1h,the certain temperature go up 1 again at the cooling mode
℃ ℃
and the certain temperature go down 2 again at the heating mode.At last sleep function shut ℃
down after running for 7h.
If press the button to increase the temperature,air-conditioner keep running according to the
new certain temprevised temperature at the sleep mode.
Cancel or shut down the sleep function if press the button of sleep
、
mode or off at the sleep
mode.The highest frequency should be 54Hz and indoor motor blow the low wind speed at the
cooling & sleep mode.
