3.10.2 Setback types
As different parameters can be entered for every heating circuit, the
setback types for every heating circuit must also be entered separately.
The settings of the setback types depend on the heating systems and the
adjustable parameters in these systems.
You can switch between the Automatic heating mode (day) and
Automatic setback mode (night) operating modes automatically via the
time program, or manually via an external contact at the FM-MM function
module.
The following settings must be made for the setback modes that are
known to date:
▶ Go to Service level > Heating circuit > Heating curve to select the
Automatic setback mode operating mode (night).
▶ Make the settings for the relevant setback type.
Reduced
The control is set to a lower set room temperature value (reduced
temperature) and continuously activates the heating circuit pump. The
control system operates by means of parallel downwards displacement
of an outside-temperature dependent heating curve.
Settings for the parameters:
Outside temperature threshold
This operating mode is a combination of the Standby mode and
Automatic setback mode. The heat source operates in Automatic
setback mode below an adjustable outside temperature and in Standby
mode above an adjustable outside temperature.
Settings for the parameters:
Standby mode (shutdown)
The heating circuit is always switched off in setback mode. In this
operating mode, the heating circuit pump is completely switched off but
the frost protection remains effective.
Settings for the parameters:
Room temperature threshold
The heating system remains in Standby mode as long as the room
temperature does not fall below a set minimum value (reduced
temperature). Otherwise the control switches to Automatic setback
mode. This function can only be activated if a remote control has been
connected in a reference room.
Settings for the parameters:
Room influence / maintenance/Room influence / maintenance and
Maximum / room maintenance mode/Maximum / room maintenance
mode
3.11 Selection of control units
Other control units on the CBC bus can only be accessed from the master
control unit.
If several control units are linked, the control unit for the system to be
operated must be selected first. The other levels (e.g. heating circuits)
can then be displayed and selected.
All functions of another control unit logged on to the CBC bus (Slave) can
be viewed and adjusted from the master control unit. The functions can
be accessed from the master control unit and at the local control unit
simultaneously.
If the same parameters are changed from the master control unit and at
the local control unit, the changes are based on the last values entered.

3.12 NM582 power supply module
The power supply module supplies voltage to the following components:
• Control unit
• Load outputs (e.g. pumps, burners, actuators)
• Control unit
• Modules used and corresponding connected system components
(e.g. sensor)
It is equipped with:
• 2 circuit breakers (10 A) as fuse protection of the power sources for
– the central module and the user interface
– the modules at slots 1...4
• ON/OFF switch, that switches the phase (L) and neutral conductor (N)
If a circuit breaker has tripped due to overload, the pin projects
noticeably out of the fuse.
To switch on the circuit breaker:
▶ Push in the pin.
If the circuit breaker is frequently triggered:
▶ Check the current consumption.
