Changing the control parameters
To optimize the control performance, a number of control parameters can be adjusted.
This can also be made during operation without opening the controller.
If you want to change the control parameters, proceed as follows:
(For factory settings, see table on the left hand side)
+
+
+
1.
Set the controller in standby
2. Press and simultaneously for a minimum of 3 and a maximum
of 5 seconds. Release them and, within 2 seconds, press
again
for 3 seconds. The display will show “P01”.
3. Select the required parameter by repeatedly pressing the or
button:
P01 P02 P22 P98
+-+
--

P99

-
P25
+-
4. Press and simultaneously. The current value of the selected
parameter will appear, which can be changed by repeatedly
pressing
or .
5. By pressing and simultaneously again or 5 seconds, after the
last press of a button, the last parameter will be displayed again.
6. If you wish to display and change additional parameters, repeat
steps 3 through 5.
7. 10 seconds after the last display or setting, all changes are stored
and the controller will return to standby.
8. Switch to normal operation with the button.
Recalibrating the sensor
If the room temperature displayed by the controller does not agree with the
temperature effectively measured, the temperature sensor can be recalibrated. For
that purpose, parameter P07 must be changed.
Proceed as described under “Changing the control parameters” and
follow steps 1 through 3 to select parameter P07.
With step 4, the room temperature displayed can now be matched to
the temperature effectively measured. Each push of the
or button
changes the temperature by + or – 0.5 °C up to a maximum of
+ / - 3 °C.
With step 7, the recalibration is automatically stored 10 seconds after
the last readjustment.
