4.200 Measured value correction outside sensor B9

• Outside temperature is acquired with more accuracy
The measured value correction compensates inaccuracies of the sensor and deviations
caused by the cable length. This enables the outside temperature to be acquired with
greater accuracy.
Setting range
-10...10

Functions

4.201 Parallel displacement of the heating curve

• Adjustment of controller's temperature scale to the actual plant conditions.
Produces a parallel displacement of the heating curve in order to achieve a better
match of room temperature setpoints and actual room temperatures.
Setting range
-4.5...+4.5
By changing the value entered, all room temperature setpoints will be appropriately
raised or lowered. This allows the room temperature setpoints to be matched to the ef-
fective room temperatures.
If a nominal room temperature setpoint of 20 °C adjusted on the controller always pro-
duces a room temperature of 22 °C (independent of the prevailing outside tempera-
ture), displace the heating curve downward by 2 °C.
Each setpoint readjustment, be it by changing the setting value or the operational level,
corresponds to a parallel displacement of the heating curve.
