Settling out of the alarm on the BM module can be delayed in the base device by
an adjustable time. This allows the prevention of unnecessary messages to a serv-
ice location from briefly occurring malfunctions (e.g. temperature monitor quer-
ied, communication errors). However, it must be realised that briefly occurring
malfunctions which continue and quickly occur again, are also filtered out with
this.
If the setting Central is activated under progr. no. 6221 and 6223, the action for
this setting can be set. The following settings are possible:
- Segment: the changeover is done for all controllers in the same segment.
- System: the changeover is done for all controllers in the entire system (that is in
all segments). The controller must be located in segment 0!
- Locally: the local heating circuit is switched on and off depending on prog. no.
730, 1030 or 1330.
- Centrally: depending on the settings made in prog no. 6620 either the heating
circuit in the segment or in the entire system is switched on and off.
- Locally: the local heating circuit is switched on and off.
- Centrally: depending on the settings made in prog no. 6620 either the heating
circuit in the segment or in the entire system is switched on and off.
- Locally: The local heating source is locked.
- Segment: All heating sources of the cascade are locked.
This setting is only necessary if the control of the DHW charging is done by a
heating circuit time program (see prog. no. 1620 and 5061)
- Local HCs: the DHW charging is done only for the local heating circuit.
- All HCs in segment: the DHW charging is done for all heating circuits in the seg-
ment.
- All HCs in system: the DHW charging is done for all heating circuits in the sys-
tem.
For all settings the controller is also considered for the DHW charging, which are
in vacation status.
With this setting the action of the system time is established on the time setting
of the controller. The following settings are possible:
- Autonomously: the time of day can be modified at the control. The time of the
controller is not adapted to the system time.
- Slave without remote setting: the time of day can not be modified at the con-
trol. The time of the controller is continually, automatically adapted to the sys-
tem time.
- Slave with remote setting: The time of day can be modified at the control. Si-
multaneously the system time is adapted, since the change is done by the mas-
ter. The time of the controller is then continually adapted to the system time.
- Master: The time of day can be modified at the control. The time of the control-
ler is the default for the system. The system time is adapted.
In the LPB system only one single outside temperature sensor is necessary. This
delivers the signal via the LPB to the controller without sensor. In the display the
segment number appears as first number and the device number is the second
number.
