The basis for an even room temperature is a characteristic
heating curve of just the right shape. The right shape for a
characteristic heating curve depends on many factors.
In Ouman EH-201/L the characteristic heating curve can be
adapted to exactly meet the needs of the facility from three
points;
EH-201/L prevents the setting of an ncorrectly shaped
characteristic heating curve. It automatically suggests an
adjustment.

CURVE INTERPRETATION:
When the outdoor temp. is:
-20 C, the supply water is +58 C
0 C, the supply water is +41 C
+20 C, the supply water is +18 C
The temperature of the supply water may vary from the curve
if a reduced operation mode, room, wind or sun compensation
has been connected to the regulator or if one of the limiting functions
limits the temperature (see p. 10).
If the outdoor sensor is disconnected or if the sensor is broken,
the regulator assumes that the outdoo temperature is 0 C (use during
construction without the outdoor sensor).
