Explanation
No boiler available. Control is used as standalone
master control unit with address 0 or as
substation.
The parameters of the SAFe are adopted by the
heat source. A boiler control is not installed in the
heat source.
The parameters of the boiler control the SAFe are
adopted by the heat source in the control unit.
The heating circuit on the central module is used
as boiler circuit.
The heating circuit on the central module is used
as boiler circuit (00).
Setting that specifies whether a boiler circulation
pump is installed.
Setting that specifies the conditions according to
which the pump is controlled
Setting that determines whether the modulating
pump is to be switched on and off via a 0....10 V
signal.
Setting that specifies the conditions according to
which the pump is controlled
Setting of the temperature differential between
temperature sensor in the system flow (FZ) and
boiler water temperature sensor.
To utilise the heat stored in the heat source to the
maximum possible extent, a time must be
specified for which the pump should continue to
operate after the burner has been shut down.
To utilise the heat stored in the heat source to the
maximum possible extent, a time must be
specified for which the pump should continue to
operate after the burner has been shut down.
Specifies the voltage at which the minimum flow
rate occurs.
Specifies the voltage at which the maximum flow
rate occurs.
5 K is added to the desired set value for the boiler
temperature, so that the set value can be reached
quickly and safely.

The control operates within the limits specified
by the SAFe, e.g. maximum boiler temperature.
Digital activation of modulating pump.
Activation: On = 10 V, Off = 0 V
Prerequisite: continuous external power supply
to pump.
▶ Observe pump manufacturer's
specifications.
Change the factory setting only in exceptional
cases.
