7.Funcitions and control
7.1 Main functions and control specification
7.1.1 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

Choose Heating Mode
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.

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
dehumidifying). When the compressor works continuously for 6 minutes and the temperature of the
indoor coils has been below one 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 9
℃
, the compressor will be restarted again (the requirement
of 3 minutes’ delay should be satisfied.)
