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.

8.4.19 Fault

A current existing error in the system is displayed here in the form of an error
code.
In case of a fault, the display fault is on permanently. In addition, the diagnosis
code is displayed on the display.
Phase, in which the fault has occurred, which led to the failure.
An output relay QX, programmed as an alarm relay can be reset via this setting.
Setting the time, after which a error message will be triggered in case of persist-
ing deviation from temperature nominal and actual values.
The last 20 error messages with error code and time of error occurrence will be
stored in the error storage.
