• Anti-seizing protection:
– The connected pump is monitored and exercised for a
short while after 24 hours of non-activity. This
prevents the pump from seizing.
– The connected mixing valve actuator is monitored and
run automatically for a short period after 24 hours of
non-activity. This prevents the mixer from seizing up.
A maximum of 6 MM100 modules are permitted in one system
irrespective of the number of other BUS nodes.
In the delivered condition, the code switch is in position 0 . The
module will only be registered in the user interface if the code
switch is in a valid position for the heating circuit or cylinder
primary circuit.
A system example with 3 heating circuits with mixing valves,
one heating circuit without mixing valve and one cylinder
primary circuit is shown in Fig. 21 on page 111. A further
example with 3 or more heating circuits and 2 cylinder primary
circuits is shown in Fig. 22 on page 112.
2.1 Importance usage notices
The module communicates via an EMS plus interface with other
EMS-plus-enabled BUS nodes.
• The module must only be connected to user interfaces with
the EMS plus (Energy Management System) BUS interface.
• The functional scope depends on the user interface
installed. Detailed information about user interfaces can be
found in the catalogue and technical guides and on the
manufacturer's website.
• The installation space must be suitable for the IP rating
stated in the module specification.

2.3 Technical data
Design and operation of this product conform to
European Directives and the supplementary
national requirements. Its conformity is
demonstrated by the CE marking .
WARNING: Risk of scalding!
▶ If DHW temperatures above 60 °C are set
or thermal disinfection is switched on, a
mixing valve must be installed at the DHW
outlet or at the DHW draw off points.
NOTICE: Floor damage!
▶ Underfloor heating systems must only be
operated with an additional temperature
limiter (MC1 connection).
NOTICE: System damage!
If a heating circuit is installed in conjunction
with a heat pump (heating/cooling),
condensate on cool system parts can lead to
damage.
▶ Only operate this heating circuit with dew
point monitor.
