•
Foot point
: Use this menu item to set the base
point of the heating curve according to the tra-
ditional foot point/end point method.
•
End point
: Use this menu item to set the end
point of the heating curve according to the tra-
ditional foot point/end point method.
•
Design flow temp.
: Use this menu item to
adapt the flow temperature setting to the
heating type:
–
For
Underfloor heating
e.g. 45 °C flow
temperature setting.
–
For
Radiators
e.g. 75 °C flow temperature
setting.
–
For
Convectors
e.g. 80 °C flow tempera-
ture setting.
•
Maximum CH flow temperature
: Use this
menu item to adapt the maximum flow tem-
perature setting to the heating type:
–
For
Underfloor heating
e.g. 55 °C maxi-
mum flow temperature setting.
–
For
Radiators
e.g. 80 °C maximum flow
temperature setting.
–
For
Convectors
e.g. 80 °C maximum flow
temperature setting.
•
Room influence
: This menu item only appears
if the controller is wall-mounted.
Use this menu item to set the room tempera-
ture influence on the heating curve:
–
0%
: No room temperature influence
–
100%
: Maximum room temperature influ-
ence
•
Room influence enabled for levels
: Use this
menu item to select the operating modes
where the room temperature influence is to
be active:
–
Eco/Frost
: Room temperature influence is
only active in these operating modes.
–
Comfort/Eco/Frost
: Room temperature
influence is always active.
•
Room temperature offset
: Use this menu item
to set the permanent increase in required
room temperature, e.g. to correct system-
related variations.
•
Heating off until lower level reached
: Use
this menu item to select the cooling down
phase:
–
No
: Heating mode corresponds to the heat-
ing curve.
–
Yes
: Heating mode corresponds to the
heating curve but without heating in the
cooling down phase. Only at the point
when the room temperature reaches the
required room temperature for the next
lower operating mode for the first time
(e.g.
Economy
with 15,0 °C) does the heat-
ing correspond to this operating mode.
•
Heating off at outside temperature
: Use this
menu item to set the outside temperature at
which the heating is to switch off:
–
10 °C
...
25 °C
: Outside temperature at
which heating switches off.
–
99 °C
: Function switched off, i.e. the heat-
ing can switch on at any outside tempera-
ture.
•
Freezing risk at outside temperature
: Use
this menu item to set the frost threshold tem-
perature at which the heating is to switch on:
–
If the outside temperature exceeds the set
frost threshold temperature by 1 K( °C)
and there is no heat demand then the heat-
ing pump in the heating circuit switches
off.
–
If the outside does not exceed the frost
threshold temperature then the heating
pump in the heating circuit switches on
(system Frost protection).
