Further step-by-step instructions (continued)
Adjusting the normal room temperature
(for every heating circuit separately)
Normal room temperature:
Select the normal day temperature with
the set value adjuster.
The value will be automatically
transferred after approx. 2 seconds.
Reduced room temperature:
1. Call up the reduced night
temperature with tm.
2. Change the value with or .
3. Confirm the set value with .

Example 1:
Adjustment of the normal room
temperature from 20 to 26˚C /
68 to 79˚F.
A Boiler water temperature or supply
temperature in ˚C / ˚F
B Outdoor temperature in ˚C / ˚F
C Set room temperature in ˚C / ˚F
D Heating circuit pump OFF
E Heating circuit pump ON
Example 2:
Adjustment of the reduced room
temperature from 5 to 14˚C /
41 to 57˚F.
Accordingly, the heating curve is
adjusted along the set room temperature
axis, resulting in modified start/shutdown
characteristics for the heating circuit
pumps, if the heating circuit pump logic
is active.
