Configuration - Select room devices
In this menu, it is possible to flexibly define the devices used to control room air temperature.
The possible options depend on setting 'Control method'. The devices must be placed in suitable
reference rooms. Refer to chapter 'Accessories installation'.
If LG room sensors are used, the sensor controlling Circuit 1 (Direct circuit) must be connected to
CN_ROOM and the sensor controlling Circuit 2 (Mixing circuit) to CN_LEAK_ROOM2.
If remote controllers are used, the ports CN_REMO_A (Direct circuit) and CN_REMO_B (Mix
circuit) must be used accordingly.
If third-party thermostats are used, the thermostat-input and/or a Dry contact can be used for
connection to the heat pump.
