NOTE
There are two optional connect method depend
on the room thermostat type.
Room thermostat type 1(RT1)(High voltage): "POWER
IN" provide the working voltage to the RT, doesn't
provide the voltage to the RT connector directly. Port "14
L1" provide the 220V voltage to the RT connector. Port
"14 L1" connect from the unit main power supply port L of
1- phase power supply, L2 port of 3-phase power supply.
Room thermostat type2(RT2)(Low voltage): "POWER
IN" provide the working voltage to the RT.
