TERMINALS

The alarm interface module is equipped with 10 screw terminals. On one side of the module, there
are terminals for supply voltage 230V/50Hz and terminals for NO (normally-open) contacts of the
output relays R1 to R3. On the opposite side, there are terminals for connecting two wires of the
serial communication line for monitoring of error messages and states of the air conditioner.
