Zone 02

Failure dependent change-over

Deﬁnition of valid alarms for one zone

For each zone any number out of 26 alarms in total can be deﬁned as valid alarms.

If such an alarm occurs the corresponding unit is switched off and notiﬁed as de-

fective.

All 26 alarms are deﬁned as valid alarms by default. The alarm "unit not available"

can not be deleted from the alarm list. This alarm is always part of the valid alarms

and appears due to a bus failure or when the unit has locally been switched off.

After the failure of a unit a standby unit is switched on. With the switching on of the

last available standby unit the time dependent sequencing is interrupted.

When the previously adjusted number of defective units in one zone is reached the

emergency operation is enabled for all zones.

Emergency operation means that the emergency temperature of the triggering zone

is accepted as the new temperature set value for all the zones.

The number of defective units is independent of the number of standby units which

have been started. For example, even if the failing unit capacity of one zone is

completely equalled by the start of standby units, the defective units are counted

as lacking.

To start an emergency operation just when the 100% unit capacity (without standby

units) is not achieved anymore, the adjusted number of defective units should be

higher than the number of a zone's standby units.

For safety reasons, valid alarms can only be conﬁgured by commands.

The corresponding commands:

Valid alarms:
