4.4 Connection to an outdoor compression unit – power limitation module
The power limitation function (evaporative pressure-temperature / condensing
pressure-temperature change request) is only available for combinations of
KM113.27UU and a compressor unit that supports this function (see LG manufacturer's
specifications).
Make sure that the compressor unit is without voltage!
There is a risk of electric shock and damage to the device when installing the
module under voltage!
Install the MOV-UU power limitation module in the outdoor compressor unit - the module is connected to the
CN-CENTRAL connector on the PCB of the compressor unit.
Connect a suitable (shielded) communication cable between the MOV-UU terminals and the "MOV" terminals of
the KM113.27UU module (terminals 29 + 30).
