3 SUPPLY WATER CONTROL IN THE HEATING CIRCUITS
The supply water temperature for dierent outdoor temperatures
is set in heating curve settings.
H1 (H2) Control circuit→ H1 (H2) Heating curve
3.2 Heating curve
you can change the regulation curve to the outdoor temperature values -20°C
and +20°C as well as to three other outdoor temperatures between -20°C and
+20°C. To change the outdoor temperature point, press OK for a long period of
time. A floor heating curve is the factory setting.
Note! Changes influence room temperature slowly. Wait at least 24 hours before readjusting the settings. Especial-
ly in buildings with foor heating, the delays in room temperature changes are quite long. The supply water minimum
limit setting ensures that pipes will not freeze. The maximum limit setting ensures that excessively hot water that
could damage structures (e.g. parquet in case of foor heating) does not enter the heating system.
If room temperature drops, make the curve steeper.
(Set higher values for supply water temperature at the outdoor tem-
peratures -20 °C and 0 °C).
If room temperature rises, make the curve less steep.
(Set lower values for supply water temperature at the outdoor tem-
peratures -20 °C and 0 °C).
Minimum allowed supply water temperature. A higher minimum tempera-
ture is used in damp rooms and tiled rooms than in, e.g., rooms having a
parquet floor to ensure a comfortable temperature and removal of moisture
in the summer.
Min. limit
12.0 °C
Maximum allowed supply water temperature. The maximum limit prevents the
temperature in the heating circuit from rising too high, preventing damage to
pipes and surface materials. If, e.g., the characteristic heating curve setting is
incorrect, the maximum limit prevents excessively hot water from entering the
network.

The preset heating curves are typical aver-
age curves for the heating mode in ques-
tion. The curve may need to be adjusted
to suit your building. The setting should
be done during the cold period and if the
room compensation is in use, it should be
switched o during the setting. The curve is
appropriate when the room temperature is
maintained constant although the outdoor
temperature changes.

You can change the supply water setting values and outdoor
temperature 2, 3 and 4 setting values by replacing the setting
value with a new one and sending a message back to the
regulator.
H23 will make the requested changes and send a new
message showing the changes made.
