7.4.3 Alarm relays
There are two floating relay outputs in the connection
box on the rear of the unit, which may be used to output
system messages from the cooling unit to an external
signal source (see section 5.4.3 "Connect the alarm re-
lays"). The relay outputs may be configured here.
 Click on the "Alarm relay" symbol to display a list of

The switch logic of the relay output, i.e. whether it is to
be used as a normally closed or normally open contact,
may be set here.
 Click on the "Switch NO/NC" symbol.
 Choose your preferred switch logic by selecting it from
the display.
 Confirm your entry with "OK".
List of functions
This is where you specify which error messages should

 If applicable, configure the other relay output with oth-
er functions.
