Further adjustments

Temperature balancing

If your Vitotrol 100 is installed in an unfavourable posi-
tion, e.g. on an external wall or near an open fireplace,
the displayed room temperature can deviate from the
actual room temperature. You can compensate for this
temperature deviation with a correction value.
Example:
The room temperature displayed by the Vitotrol 100 is
2 °C higher than the actual room temperature. The cor-
rection value is then 2 °C.

Control characteristics

The hysteresis controller is factory-set. The hysteresis
value influences the start and stop times for "Heating"
or "Not heating".
Example:
Set room temperature: 21 °C
Hysteresis: 0.6 °C (factory setting)
As soon as the actual room temperature exceeds
21.3 °C, heating is stopped. Heating starts as soon as
the actual room temperature falls below 20.7 °C.
You can change the control characteristics by chang-
ing the hysteresis value. Select a lower value if your
system responds too slowly.
