7.3 Main Protection
7.3.1 Three minutes delay at restart for compressor.
7.3.2 Sensor protection at open circuit and breaking disconnection.
7.3.3 Indoor fan delayed open function
----When system starts up, the louver will be active immediately, and the indoor fan will open after 10s..
----If the system runs in heating mode, the anti-cold wind function has priority.
7.3.4 Fan speed is out of control(For the units used DC fan motor)
When indoor fan speed is too low (less than 300RPM) and lasts 50 seconds, the system will consider that
the fan speed is out of control and will go into fan speed protection. Then VSP signal of indoor fan will be
shut off and the compressor will be also shut off if the compressor is running at that time. The louver does
not act and there won't be any error code displayed. After 30 seconds, this protection will be canceled and
the indoor fan will restart as well as the compressor (under the 3-minute-delay condition).As long as the fan
speed is normal (not lower than 300 RPM) or fan is off, the protection will be canceled and the timing will be
cleared to 0. If the protection occurs 3 times during continuous 3 fan starts, the whole unit stops and LED
displays failure information and can’t returns to normal operation automatically.
7.3.5 Inverter module protection
The Inverter module has a protection function about current, voltage and temperature. If these protections
happen, the corresponding code will display on indoor unit and the unit will stop working.
