6.4.8.4 Temperature alarm limits

Changes in the factory-preset alarm limits should only be
made if you have special reasons for doing so and you
should be aware of the consequences.
Pre-heating below set point
You can preset how much the temperature downstream of the
pre-heater should be permitted to be below the temperature set
point before an alarm is initiated.
Supply air below/above set point
You can preset how much the supply air temperature shall be
permitted to be below or above the supply air temperature set
point before an alarm is initiated. The alarm for supply air above
the set point is normally blocked. Used in the cases in which
cooling is installed.
Extract air below alarm limit
You can preset how much the extract air temperature shall be
permitted to be below the extract air temperature set point
before an alarm is initiated.

16;1-16:4, 17:1, 17:4-17:9 (see Section 8.2), the following

The air handling unit's service period can be set here. The re-

after the time interval has expired. If you reset the alarm in the
alarm log, the alarm will trip again after 7 days. Following com-
pleted service, the alarm must always be reset in this menu and
this will launch a new service interval.
