Selecting the type of curve
Device settings -> H1 Process settings -> Heating curve type
Select either a 3 point or 5 point curve here. A 3 point curve is the
default, so the controller prevents selection of a curve of the wrong
shape.
3 point curve:
The supply water temperature is set at outdoor tem-
peratures of -20°C, 0°C and +20°C. The controller prevents an incor-
rectly shaped curve from being set by automatically correcting the
curve.
The 5 point curve is adjusted in the H1 Heating curve menu as fol-
lows: Set the supply water temperatures for outdoor temperatures
+20, +10, 0, -10 and -20 °C.
A 5 point curve
offers even more possibilities to make a curve of
just the right shape to exactly meet the heating need of your facili-
ty. A 5 point curve does not have automatic correction of incorrectly
shaped curves.
Press OK for a number of seconds to change the setting points for
outdoor temperatures b20 and -20°C (the factory set points
are +10, 0 and -10°C).
