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. The unit will shut down for 5 minutes and the 
temperature of the coil rise to 10°C (E) , it will be back up and running.
6.1.5 Control of oat switch and condensate pump:
1.in the cooling and the dehumidication modes the condensate pump will run when the compressor starts and will 
shut off 5 minutes after the compressor stops.
2. When in the cooling mode and there is a call for heating, the condensate pump will continue to run for 5 minutes.
3. If the unit detects a full water signal for more than 5 minutes, the compressor will shut off.  The pump will 
continue to run for 5 minutes after the compressor stops.  If the full water signal is still indicated, the  unit will 
show a drainage system error.  The pump will continue to run for 5 minutes after the error is cleared.
6.1.6 Emergency switch
1. Emergency switch operation
If the emergency switch is pressed when shutting down the system, the set temperature is locked at 75 degrees F.      
Pressing the switch again during start-up will return the system to normal.
2. Test run
To enter the test mode, press the emergency button for 5 seconds until two beeps are heard then release.  The unit 
will maintain the last mode it was in before the shutdown.  If in cooling, the temperature will be locked at 61 degrees 
F with high speed fan.  Heating will be locked at 86 degrees F with high speed fan.  To disable the test mode, press 
the emergency button again or use the wired or remote controller.
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. With the remote controller, press the SLEEP button 10 times within 5 seconds.  The controller will beep 4 times 
then enter the auto restart function.  To exit, press the SLEEP button 10 times within 5 seconds.  The controller 
will beep 2 times then exit auto restart.
Auto restart default memory: ON/OFF/MODE/FAN/SET TEMP/HEALTH/SWING.  If the timer or sleep functions are 
set, they will be canceled when power is reapplied.
6.1.9 Forced defrost:
1. When using remote controller: when outdoor in heating or off state, set high fan, 86 degrees F, press sleep key 6 
times in 5 seconds, and indoor beeps 3 times to enter manual defrosting. 
2. When using wired controller : it will receive corresponding forced defrost signal and enter defrost.
