• Local heating circuits:
DHW is only heated for the local heating circuit
• All heating circuits in the segment:
DHW is heated for all heating circuits in the segment
• All heating circuits in the system:
DHW is heated for all heating circuits in the system.
With all settings, controllers in holiday mode are also considered for DHW heating.
This setting defines the impact of the system time on the controller's time setting. The
impact is as follows:
• Autonomous: The time of day on the controller can be readjusted
The controller's time of day is not matched to the system time
• Slave without remote adjustment: The time of day on the controller cannot be
The controller's time of day is constantly and automatically matched to the system
• Slave with remote adjustment: The time of day on the controller can be readjusted;
at the same time, the system time is readjusted since the change is adopted from the
The controller ' s clock time is still automatically and continuously matched to the
• master: The time of day on the controller can be readjusted
The time of day on the controller is used for the system. The system time will be
Only 1 outside temperature sensor is required in the LPB plant. This sensor is
connected to a freely selectable controller and delivers via LPB the signal to the
controllers without sensor.
The first numeral to appear on the display is the segment no. followed by the device no.
When a fault
is pending, an error message can be displayed on the info level by
pressing the Info button. The display describes the cause of the fault.
Reset alarm relay
When a fault is pending, an alarm can be triggered via relay QX... The QX... relay must
be appropriately configured.
This setting can be used to reset the alarm relay.
Flow temp 1 alarm
Flow temp 2 alarm
The difference of setpoint and actual temperature is monitored. A control offset beyond
the set period of time triggers an error message.
The basic unit stores the last 10 faults in nonvolative memory. Any additional entry
deletes the oldest in the memory. For each error entry, error code and time of
occurrence will be saved.
