When this option is activated, the heating circuit opens
(mixer opens) and the heating circuit pump is switched
on (provided that the chimney sweeper function is
active, see 4.4). The protective function of the heating
pump maximum limitation will still be active.
Up to 3 additional external heating circuit modules
(HKM) can be activated if further compensated heating
circuits are required.
If the external heating circuit module HKM is additional-
ly used, only 1 outdoor temperature sensor is required.
In order to ensure that all heating circuits control using
the same outdoor temperature, adjust to sensor 13 and
connect the external sensor to the HKM module.
This function switches off the heating circuit when
domestic hot water is being afterheated.
For this purpose, the option domestic hot water priority
and afterheating via store loading (see 4.2) of the con-
troller COSMO Multi have to be active as well.
The displays and functions are comparable to those of
the internal heating circuit (see also manual „COSMO
HKM").
The controller has a separate integrated calorimeter
which can be configured with or without flowmeter V40.
Furthermore, the values of a separate WMZ module can
be displayed.
Allocate the sensors. Factory settings are as shown –
but other sensors can be allocated without influencing
their orginal function in the system.
