A settings screen opens:
Enter the new temperature difference for the "Set-
back". Subtracting the "Set-back" from the heating
curve "Day" gives you the heating curve "Night".
Press [Accept] to save the new value. The text
menu for the selected heating circuit is displayed
once more.
Press to return to the heating circuit overview.
The parameter "Set-back"
If the unit does not have a room sensor, the
parameter "Set-back" is used to adjust the night
mode. The control system subtracts the "Set-back"
parameter from the heating curve "Day" to get the
heating curve "Night".
Outside the time slots set in the timer, the heating
circuit is in "Night" mode, and runs using the
heating curve "Night".
The factory setting for this "Set-back" is 15°C.
The "Set-back" can be adjusted for each
heating circuit
. The following steps are the same
for all heating circuits.
Do not use large set-backs
Do not overuse "set-back", as much higher air
temperatures will be required to ensure comfort
in the morning if the walls have cooled down too
much overnight. In addition to reducing comfort,
this also wastes the energy saved overnight.
Depending on the "Flow at -10°C" temperature
and the type of heating circuit used (radiator or
underfloor heating), the following guidelines apply
for the set-back:
Temperature
Radiator Underfloor
Flow at -10°C
40°C 60°C 80°C 30-40°C
Set-back
5-8°C 10-15°C 15-22°C 3-5°C
