The system control queries whether a signal is present at the heat pump's input. For example:
–
aroTHERM input: MI for the heat pump control module
–
flexoTHERM input: X41, terminal in the functional drawing

In the case of excessive current, the buffer cylinder is heated up to the flow temperature +
set offset via the heat pump. Prerequisite:
–
A photovoltaic installation is connected.
– Photovoltaics is activated in the HP control module configuration → MI: function.
→ Off
The system control always actuates the heat generators in the sequence
1, 2, 3, etc.
→ On
Once a day, the system control sorts the heat generators based on their
actuation time.
The back-up heater is excluded from this sorting.
Prerequisite: The heating installation contains a cascade.
Sequence in which the system control actuates the heat generators.
Prerequisite: The heating installation contains a cascade.
Select whether the external heating circuit is deactivated using a bridge or open terminals.
Prerequisite: The FM5 and/or FM3 functional module is connected.
Systems are roughly grouped according to their connected system components. Each group
has a basic system diagram code. Based on the code that is entered, the system control
enables the system-related functions.
You can use the connected components to determine the basic system diagram code for the
installed installation (→ Using the functional modules, basic system diagram, start-up) and
enter this here.
Each configuration corresponds to a defined terminal assignment (→ Connection assignment
for the FM5 functional module). The terminal assignment determines which functions contain
the inputs and outputs.
Select the configuration that suits the installation that is installed.
Each configuration corresponds to a defined terminal assignment (→ Connection assignment
for the FM3 functional module). The terminal assignment determines which functions contain
the inputs and outputs.
Select the configuration that suits the installation that is installed.

Select the multi-function output's function assignment.
→ Not connec-
The system control ignores the signal present.
ted
→ 1 x circula-
The end user has pressed the circulation button. The system control
tion activates the circulation pump for a short time period.
→ Photovoltaics
In the case of excessive current, a signal is present and the system con-
trol activates the DHW boost function once. If the signal persists, the
buffer cylinder is charged to the flow temperature + buffer cylinder offset
until the signal at the heat pump drops off again.
→ Inactive
The heating circuit is not being used.
→ Heating
The heating circuit is being used to heat and is weather-compensated.
Depending on the basic system diagram, the heating circuit may be a
mixing circuit or a direct circuit.
→ Fixed value
The heating circuit is used for heating and is maintained at a fixed target
flow temperature.
→ DHW
The heating circuit is being used as a domestic hot water circuit for an
additional cylinder.
