In the main menu select the item “Specialist Level” and enter the code “100”. Now you have access to the settings
for the specialist level.

Menu item – Heating Circuits
4.1.1
Operating
values
Maximum temp.:
Maximum forward flow temperature
Minimum temp.:
Minimum forward flow temperature
Gradient:
The control unit calculates the necessary forward flow temperature for the heating circuits
from the outdoor temperature, the target room temperature, and the heating curve gradient.
This temperature is adjusted through mixer control (colder return flow water mixed with the
forward flow water).
Base shifting
For the heating curves, setting of a reference point offset of +/– 10 °C is possible. The
gradient of the heating curve is changed automatically in this process so that the forward
flow temperature remains constant at – 20 °C.
Ambient influence : Here you can enter the extent to which the calculated forward flow temperature will be
corrected by the room sensor. If the actual temperature is greater by 1 °C than the target room
temperature, then the forward flow temperature at 100 % (200 %) room influence , will be
calculated for a room temperature that is 1 °C (2 °C) under the target room temperature.
Fast lowering:
On: The heating circuit pump switches off when the actual temperature is one degree
Celsius higher than the target room temperature. (The release is executed according
to the spread)
Off: The heating circuit pump always runs and constantly maintains the temperature at
the target level. (Recommended setting for underfloor heating systems)
Pump release:
Specifies how the pump release is executed
Auto: Pump release, if the boiler or buffer temperature is greater than the target forward
flow temperature.
On: Pump release, regardless of boiler or buffer temperature.
Temp: The pump is released depending on the value in the next menu item, “Release
temperature” if this value is under the actual boiler or buffer temperature.
Release
temperature:
Pump release, if in the previous menu item, “Pump Release” > “Temp” was selected and
the boiler temperature or buffer temperature is greater than the set Release temperature.
Runn. time, mixer:
Runtime of the mixer at a cycle in seconds (factory setting 5 s).
Pause mixer:
Idle time of the mixer at a cycle in seconds (factory setting 10 s).
