Note:
①、
If the unit stops in defrosting period, next defrosting interval is 50 minutes.
②、
Defrosting ends, the total working time of the compressor will be clear.
4) Defrosting ends condition: (when any one of following meet)
1. Defrosting continue working for 15 minutes.
2. Outdoor thermistor is equal or higher than 22
℃
within the first 75 seconds of the defrosting
beginning.
3. Outdoor thermistor is equal or higher than 22
℃
after 75 seconds of the defrosting beginning.
4. Defrosting period, the power switch is on off butoon.
5) Indoor unit abnormal inspection in defrosting period:
If following condition occurs, the compressor will stop, indicator show trouble.
1. Ta - Tc
≤
5
℃
, continue time is more than 30 minutes.
2. Tc - Ta
≤
5
℃
, continue time is more than 20 minutes.
5. Controller
1) Distributary valve control:
①
Cooling:
1. When anti frosting function lead to the unit stopping, distributary valve opens, when the compressor
stops for more than 1 hour, distributary valve shuts down.
2. When distributary valve is shut down, the compressor stops, distributary valve opens and last for 3
minutes.
②
Heat:
1. First power on, or the compressor open for more than 30 minutes and restart, if outdoor coil
temperature is equal or higher than 12
℃
, distributary valve open.
2. When high pressure switch
(
63H1
)
works, distributary valve opens.
3. When distributary valve opens for 30 minutes, if high pressure switch restarts, distributary valve
shuts down.
4. When operation mode changes or stops, distributary open and last 3 minutes.
Note: distributary valve’s existence make it unnecessary to shut down the compressor in high pressure trouble.
③
Dehumidifying: distributary valve shuts down.
2) Brace axis heater control
:
①
Without short circuit board J3, from power on to the compressor runs, (or after 1 hour of the
compressor’s stopping), the brace axis heater open.
②
With short circuit board J3, from power on to the compressor runs, brace axis open and operate as the
principle of 1- hour- on, 1-hour-off.
6. Service function:
1) Forcible defrosting: when all below condition meet, press SW2 forcible defrosting works.
1. In heat mode;
2. The compressor runs;
3. Lighting tube shows outdoor coil temperature
