INSTALLATION
The power supply 230V/50Hz is connected from the upper side of the module.
The serial communication cable is connected from the bottom side. It is necessary to observe the
polarity of the A/C communication line, i.e. connect the COM+ wire to the A/C terminal marked "2"
and connect the GND wire to the A/C terminal marked "1(N)". It does not matter whether you
connect the communication line to the indoor unit or the outdoor unit of the A/C system.
