Supplementary sources connected via the LPB bus can be locked or released (e.g.
air/water HP) pursuant to its own parameters. The status is distributed via LPB.
Thus a master knows in a cascade whether a supplementary source (slave)
available according to its own employment limits (outside temperature) and can
switch on another source accordingly.
No
The Ecobit from the external generator is not observed.
Note: If an LMU control (slave) is connected as an additional generator, the
parameter must be set to "No"!
Yes
The Ecobit from the external generator is observed and the cascade is controlled
per the provided generators.

This setting defines the action of the system time on the controller's time settings.
The effects are as follows:
Autonomously
The clock on the controller can be adjusted.
The controller's clock is not adapted to the system clock.
Slave without remote setting
The time of day on the controller cannot be readjusted.
The controller's time of day is constantly and automatically matched to the system
time
Slave with remote setting
The time of day can be readjusted on the controller; at the same time, the system
time is adapted since the change is adopted from the master.
Nevertheless, the controller's time of day is automatically and continuously
matched to the system time.
Master
The time of day can be readjusted on the controller.
The time of day on the controller is used for the system: The system time is
adapted.
The LPB plant requires only 1 outside sensor. This sensor is connected to any
controller and delivers via LPB the signal to the controllers with no sensor.
The first numeral that appears on the display is the segment number followed by
the device number.
