Remote alarm ports (CN33)
There are reserved ports for connecting a remote alarm installed in central control room or somewhere
like it, which will be active when the A/C unit is faulty or in a protection state.
These 2 ports are dry contacts and there
is no power output but a ON/OFF signal.
The alarm components and the power
supply are prepared by the users or
installers.
