NOTE
There are two optional connect method depend
on the room thermostat type.
Room thermostat type 1(RT1): "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)(Recommend
connection method): L N provide the power supply to the
RT connector directly. L connect from the unit main
power supply port L of 1-phase power supply , L2 of
3-phase power supply.
