2.7.5 Control of one heating pump
In heating systems with only one heating zone, the heating
pump can be connected directly to the MCM10 module
(master).
The heating pump runs:
• as long as at least one heating appliance pump is
running (if required, set the pump run-on time on the
heating appliance accordingly Æ heating appliance
installation instructions); or
• briefly after remaining idle for 24 hours (anti-seizing
protection).
2.7.6 External switching contact
The MCM10 module is equipped with an external
switching contact (Æ Fig. 12, pos. G). For the
characteristics of this switch, see Æ Tab. 2, page 5.
This external switching contact can be used optionally,
e.g. to connect a temperature switch for protecting the
radiant floor heating against a too-high water temperature.
If the switching contact is opened, all heating appliances
are switched off via the MCM10 module. As soon as the
switching contact is closed again, the heating appliances
are ready for operation again.
2.7.7 System versions overview
As a manufacturer of advanced heating technology, we
give high priority to the development and manufacture of
economical and clean-burning heating appliances. To
guarantee this, our heating appliances are equipped with
modulating burners. To make optimum use of the burner
characteristics, heating system controls with 2-wire BUS
control should be used.
The anti-seizing pump protection lets the
heating pump run at least once every day
even without a heat demand (e.g. during
summer).
B Leave your heating system switched on all
year to prevent the pump (in summer) from
seizing up.
