Function
Off
:
No heating operation, only DHW loading possible. Menus and parameters relating
to the heating circuit are hidden.
On
:
Heating operation possible. Menus and parameters relating to the heating circuit
are displayed.
Demand
Weather compensated
:
With weather compensated control, the flow temperature is regulated depending
on the external temperature.
The current flow temperature is calculated from the:
external temperature,
heating characteristics curve [ch. 6.7.3.3],
room setpoint temperature.
Fixed value
:
The flow temperature is regulated to the value set under
Constant temperat-
ure
Screed
Off
:
Screed program deactivated.
Function specific heating
:
Function specific heating curve activated. First phase of drying. The function spe-
cific heating is used to ensure defect-free preparation for underfloor heating.
Screed drying
:
Screed drying curve activated. Second phase of drying. Screed drying is used to
continue drying ready for floor covering work.
Function specific heating and screed drying
:
Function specific heating and screed drying activated one after the other.
External sensor alloca-
tion
Defines the relevant external sensor for the control.
External temperature
:
External sensor B1 (accessory) [ch. 5.5.1].
Air intake temperature
:
Air intake sensor (OAT) in outdoor unit.
Frost protection
Off
:
Frost protection deactivated.
-20°C … +29°C
:
If the current external temperature drops below the value set, system frost protec-
tion is activated.
SG Ready increase
Increase of flow setpoint temperature in heating operation with Smart-Grid func-
tion in operating mode 3 [ch. 11.2].
Constant temperature
Fixed flow temperature for heating operation. This parameter only appears, if the
option
Fixed value
has been set under
Demand
.
Setback mode
Temperature level for the setback phases in the heating program [ch. 6.7.3.2].
