When TM<6°C, the compressor frequency will decrease at the speed of 1HZ/10s;
When TM start to rise again, and 6°C<=TM<=8°C, the compressor frequency will remain unchanged.
When 8°C<TM<=10°C, the compressor frequency will rise at the speed of 1HZ/10s.
When the state of TM<2°C lasts for 10s after 6 minutes of the startup of the compressor, or the state of T<-20°C (E)
lasts for more than 2 hours in cooling mode, the compressor will stop. Shut down the units for 5 minutes (E) and the
temperature of the coil rise to 10°C (E) , it will be back up and running.
6.1.5 Control of float switch and drainage pump
1.In cooling (including cooling automatically and emergent switch setting cooling) and dehumidication mode,
the drainage pump will work when the compressor startup and will stop working after 5 minutes when the
compressor shuts down.
2. In convert heating and other modes, the drainage pump also keep working for 5 minutes and predicate execution
according to the mode.
3. Detecting the full water signal for more than 5 minutes, the compressor will stop working; The water drainage
pump will keep working for 5 minutes after the compressor stops, if the oat switch is still off, then the drainage
system will show errors, the water drainage pump will keep working after the error comes out until 5 minutes
after detecting the oat switch is off.
6.1.6 Emergent switch control
1. Emergent running
Press the emergent switch when shutting down the unit, the indoor unit will startup at *** mode automatically, the
speed of the wind is automatic, setting temperature is 24°C, press the emergent switch when starting up the unit,
the indoor unit will shut down, then it come to the normal control.
2. Test run
When in shut down state, keep pressing the emergent button, you will hear two buzzers after 5 seconds and then
release the button to remember the last shutdown mode, if it’s cooling mode last time, it’s cooling, high speed
wind and setting 16°C now, if it’s heating mode, it’s heating, high speed wind and setting 30°C now, the way to
quit this: wired controller to start up or shut down the unit, remote controller to start up or shut down the unit,
emergent switch.
6.1.7 Room card control (default is valid)
Room card invalid: if room card is invalid, using room card to turn ON/OFF (ON when close and OFF when open) is
valid, similar function to other controller.
Room card valid: if room card is valid, indoor will operate only when room card closes and then receives ON order
from other controllers.
6.1.8 Auto restart function:
1. When using wired controller: auto restart function is default valid (no need to set)
2. When using remote controller: press continuously 10 times of sleep key in 5s, indoor beeping 4 times to enter
auto restart function; press continuously 10 times of sleep key in 5s, indoor beeping 2 times to quit auto restart
function;
Memorized content of auto restart: ON/OFF state, mode, fan, set temp, health, swing position;
If timing or sleeping function is set, when power on again, they will be cancelled.
6.1.9 Forced defrosting:
1. When using remote controller: when outdoor in heating or off state, set high fan, 30°C, press sleep key 6 times in
5s, and indoor beeps 3 times to enter manual defrosting. It is the same as heating defrosting.
2. When using wired controller or invisible LED: it will receive corresponding forced defrosting signal and enter
defrosting.
