In the default setting any changes in the outside
temperature have an effect after a delay of three hours at
the latest on the calculation of the weather-
compensated control.

If a heat requirement comes from heating circuit
1
and
others simultaneously. this setting is used to determine whether the
heat requirement forthe other heating circuits is always met Depending
on the setting. the heat requirement forthe other heating circuits is only
met if heating circuit
1
is supplied accordingly_

No
Heating circuit 1 is the primary heating circuit. Heat requirements for other circuits are only handled if heating circuit
1
1
has a heat requirement. The flow temperature required for heating circuit 1 limits the flow temperature of the other
heating circuits_
Example: HK1 requires 50 'C. HK2 requires 55 "C. but receives a maximum of 50'C (in line with HK1). HK3 requires
45'C and receives 45'C (notlimited by HK1).
Unmixed heating circuit 1 will be forced to run when any other circuit requests heat. So heating circuit 1 might have a
higher temperature then wanted.

Settings for the individual heating/cooling circuits can be made in this
menu. For example. you can set which heating system is installed for the
selected heating/cooling circuit. In addition it can be set whether a
remote control is available and which control type is used. It is also
possible to optimise the heating curves of the heating/cooling circuits.

If an underfloor heating system is used. the max. flow
temperature recommended by the manufacturer of
the system should be observed.

A heating/cooling circuit is not installed. If no heating/cooling circuit is installed. the heat source is only
used for DHW heating.
Electrical assemblies and components of the selected heating/cooling circuit are directly connected to the
I
heat source (only available with heating circuit
1).
Electrical assemblies and components of the selected heating/cooling circuit are connected to an MM 100
module.
CR 10 is installed as a remote control for the heating/cooling circuit. This allows
compensated control influenced by room temperature.
