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 203GT the characteristic heating curve can be
adapted to exactly meet the needs of the facility from three points;
203GT prevents the setting of an incorrectly shaped charac-
teristic heating curve. It automatically suggests an adjustment.

2. outdoor temperature of

CURVE INTERPRETATION:
When the outdoor temp. is:
-20 C, the supply water is +32 C
0 C, the supply water is +27 C
+20 C, the supply water is +21 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. 11).
If the outdoor sensor is disconnected or if the sensor is broken,
the regulator assumes that the outdoor temperature is 0 C (use during
construction without the outdoor sensor).
