If a VR 60 is connected, this menu appears several
times (for each heating circuit).
Type: Direct circuit (for direct hydraulic systems),
Mixed circuit (for buffered hydraulic systems),
Fixed value.
Heating curve: Adjustable heating curve (not with
fixed value).
Max limit outs.temp.: Temperature threshold for
switching off Heating mode (summer function).
Comp.starts at: Set the degree minutes until com-
pressor start (only with direct hydraulics).
Minimum/maximum flow temp.: Setting the limiting
temperatures (min. and max.) that the heating
circuit can request.
The maximum flow temperature is also used to
calculate the value for the underfloor protective
circuit (maximum HC tempe compressor
hyst 2 K).
If the mixed circuit heating circuit type is set,
the underfloor protective circuit is disabled and
the factory setting is 50 °C.
Heating curve: The heating curve represents the
relation between the outside temperature and
target flow temperature. The setting is made
separately for each heating circuit.
The efficiency and convenient operation of the
heating system significantly depend on the
selection of the correct heating curve. If too
high a heating curve is selected, the tempera-
ture in the heating system will be excessive and,
as a result, energy consumption will be higher. If
the selected heating curve is too low, the
desired temperature level may only be reached
after a while or not reached at all.
