5.1 Main functions and control specification of indoor unit
5.1.1 Automatic operation
When the running mode is turned to automation after starting the system, the system will first
determine the running mode according to the current room temperature and then will run according to
the determined mode. Tr in the following selection conditions means room temperature, Ts means
setting temperature, Tp means temperature of indoor coil pipe
Tr≥23
Choose Cooling Mode
ć
Tr˘23
Choose Heating Mode
ć
After turning to the automation mode, the running mode can be switched between cooling mode, fan
mode and heating mode according to the change of the indoor ambient temperature. But the
automatic conversion between cooling mode and heating mode must be conducted after 15 minutes.
5.1.2 Cooling operation mode
Temperature control range: 16ć---30ć
Temperature difference: !1ć
* Control features: When Tr˄input airflow˅>Ts˄set temperature˅ , the compressor will be opened,the
ć
indoor fan will operate at the set speed and the mode signal will be sent to the outdoor system. When
Tr˄input airflow˅" Ts˄set temperature˅ , the compressor will be opened,the indoor fan will operate
ć
at the set speed and the mode signal will be sent to the outdoor system. The system will keep the
original status if Tr= Ts.
Airflow speed control: (temperature difference 1

ć
When Tr , low speed ć When the sensor is off, low speed When the airflow speed has no delay from the high to low switching, the speed should be delayed for 3 minutes (remain at high speed for 3 minutes.) before the next switch. Manus: When the system is operating, you can set the high, medium or low speed manually. ( When the sensor is on or off, the system will change the speed 2 seconds after receiving the signal.) *Airgate location control: the location for the airgate can be set according to your needs. *Defrosting function: preventing the frosting on the indoor heat exchanger (when cooling or demoisture). When the compressor works continuously for 1/6 minutes (adaptable in EEPROM) and the temperature of the indoor coils has been below zero centigrade for 10 seconds, the compressor will be stopped and the malfunction will be recorded in the malfunction list. The indoor system will continue to run. When the temperature of the indoor coil is raised to 7 , the compressor will be ć restarted again (the prerequirement of 3 minutes’ delay should be satisfied.) * timing system on/off function. * Dormant control function.
