The flow temperature setpoint for the "manual" floor curing function can be set
separately for each heating circuit.

After a power failure, the plant resumes the floor curing function at the point in time the
power failure occurred.
Start in the summer
In the case of heat pumps controlled according to the return temperature, the switch-on
point for the heat pump may not be reached during the summer.
For this reason, the return temperature needed for switching on the heat pump is
calculated based on the flow temperature setpoint minus the required temperature
differential (5801). If the temperature acquired by the return temperature sensor lies
above that temperature, the heat pump will not be put into operation and, therefore, the
floor curing function be started too late (only when the temperature increase resulting
from the floor curing function requires the heat pump to be switched on).

Excess heat draw can be triggered by some other device via bus or by storage tank
recooling.
When dissipation of excess heat is activated, it can be drawn by space heating. This
can be selected separately for each heating circuit.
Off
Excess heat draw is deactivated.
Heating mode
Excess heat is drawn only when the controller operates in heating mode.
Always
Excess heat is drawn in all operating modes.
Line no.

If there is a buffer storage tank, state whether the heating circuit can draw heat from it.
When using alternative heat sources, the buffer storage tank temperature is used as a
control criterion for the release of additional heat sources.
Select whether the heating circuit shall receive its heat via the primary controller or with
the help of the system pump (depending on the type of plant).
