The system control regulates the heating circuit to the Min. cooling targ. flow temp.: °C.
Prerequisite: The Cooling possible: function has been activated.
Safety margin that is added to the current dew point. Prerequisite:
The Cooling possible: function has been activated.
The Dew point monitoring: function has been activated.
Display showing whether a heat demand is present at an external input.
When installing an FM5 or FM3 functional module, external inputs are available, depending
on the configuration. You can connect an external zone controller, for example, to this ex-
ternal input.
Desired temperature at the withdrawal point. The heating circuit is used as a domestic hot
water circuit.
The heating circuit is used as a domestic hot water circuit.
Deactivate zones that are not required. All existing zones appear in the display. Prerequisite:
The existing heating circuits are activated in the Circuit type: function.
Assign the system control and/or remote control to the selected zone. The system control
and/or remote control must be installed in the selected zone. The control system also uses
the room temperature sensor for the assigned unit. The remote control uses all of the val-
ues for the assigned zone. The Room temp. mod.: function is ineffective if you have not as-
signed any zones.
If there is an existing domestic hot water cylinder, the Active setting must be selected.
Define the days on which you want the anti-legionella function to run. On these days, the
water temperature is increased to above 60 °C. The circulation pump is activated. The func-
tion ends after 120 minutes at the latest.
If the Absence function is activated, the anti-legionella function is not carried out. As soon
as the Absence function ends, the anti-legionella function is carried out.
Heating installations with heat pumps use the back-up boiler for legionella protection.
Define the time at which you want the anti-legionella function to run.
The cylinder charging starts as soon as cylinder temperature < desired temperature - hyster-
esis value.
Desired temperature + offset = flow temperature for the domestic hot water cylinder.
Setting the maximum time at which the domestic hot water cylinder can be charged without
interruption. If the maximum time or the target temperature is reached, the system control
enables the heating function. The setting Off means that the cylinder charging time is not
restricted.
Setting the time period during which the cylinder charging is blocked after the maximum cyl-
inder charging time has elapsed. During the blocked time, the system control enables the
heating function.
When charging the domestic hot water cylinder, the mixing circuit is heated in parallel. The
non-mixed heating circuit is always switched off during cylinder charging.

Actual temperature in the lower section of the solar cylinder
