Function description /
System engineering
Generally, at least one programming module BM is required. This enables both
individual heating circuits and up to 8 heating circuits (1 direct and 7 mixer
circuits) to be operated and adjusted.
Cylinder heating is controlled by the KM or MM. The cylinder sensor is connected
to E1 of the KM/MM and the cylinder primary pump to A1 of the KM/MM, see
installation instructions for KM/MM.
The cascade module KM comprises a cascade control for switching and
modulating boilers, including a header sensor that acts as a common flow
sensor. The KM also comprises a mixer circuit control and the control for a
programmable output. Parameter settings are made via the programming
module BM with address 0.
The following configurations (system schemes) are available in the KM:
Configuration 1 Mixer circuit and cylinder heating with primary pump
Configuration 2 Mixer circuit and convector heater circuit
Configuration 3 Mixer circuit and heating circuit
Configuration 8 Mixer circuit (factory setting)
Configurations 4-7, 9-13 See KM installation instructions
The mixer module MM comprises a mixer circuit control and the control for a
programmable output. Parameter settings are made via a central programming
module BM.
The following configurations (system schemes) are available in the MM:
Configuration 1 Mixer circuit and cylinder heating with primary pump
Configuration 2 Mixer circuit and air heater circuit
Configuration 3 Mixer circuit and heating circuit
Configurations 4-7 Return temperature raising facility (not required for
condensing boilers)
Configuration 8 Mixer circuit (factory setting)
Configurations 9-11 See MM installation instructions
A maximum of 6 mixer modules and 1 cascade module can be combined in
each system, i.e. up to 7 mixer circuits. The direct heating circuit should only
be allocated once in the system. A maximum of eight heating circuits are
therefore possible.
