Each configuration corresponds to a defined FM5 terminal assign-
ment (→ Section 4.5). The terminal assignment determines which
functions contain the inputs and outputs.
Select the configuration that suits the installation that is installed.

Factory setting: Circulation pump
The system control queries whether a signal is present at the heat
pump's input. For example:
–
aroTHERM input: MI for the heat pump appliance interface
–
flexoTHERM input: X41, terminal in the functional drawing
Factory setting: 1 x circulation
The system control ignores the signal present.
The end user has pressed the circulation button. The system con-
trol activates the circulation pump for a short time period.
In the case of excessive current, a signal is present and the sys-
tem control activates the Hot water boost function once. If the sig-
nal persists, the buffer cylinder is charged to the flow temperature
+ buffer cylinder offset until the signal at the heat pump drops off
again.
The signal of an external control is used to switch between heating
and cooling.

The heating circuit is not being used.
The heating circuit is being used to heat and is weather-com-
pensated. Depending on the basic system diagram, the heating
circuit may be a mixing circuit or a direct circuit.
The heating circuit is used for heating and is maintained at a fixed
target flow temperature.
The heating circuit is being used as a domestic hot water circuit for
an additional cylinder.
The heating circuit is used for the increase in return. The increase
in return prevents an excessive temperature difference between
the heating flow and return, and protects against corrosion in the
floor-standing boiler when the dew point is not reached for an ex-
tended period.
