4.15 Control parameters
A number of control parameters can be readjusted to optimize control performance.
These parameters can also be set during operation without opening the unit. In the
event of a power failure, all control parameter settings are retained.
The control parameters are assigned to 2 levels:
"Service level", and
"Expert level" with "Diagnostics and test"
The "Service level" contains a small set of parameters to set up the thermostat for the
HVAC system and to adjust the user interface. These parameters can usually be
adjusted any time.
Change parameters at the "Expert level" carefully, as they impact control performance
and functionality of the thermostat.
Change the parameters as follows:
1. Press left and right button simultaneously for 4 seconds.
Release and press the right button again within 2 seconds until the display shows
"P01".
Continue with step 2.
1. Press left button and right button simultaneously for 4 seconds.
Release and press the left button again within 2 seconds until the temperature
disappears. Turn the rotary knob counterclockwise min. ½ rotation.
The display shows "Pxx".
Continue with step 2.
2. Select the required parameter by turning the rotary knob.
3. Press
button
(OK); the current value of the selected parameter starts blinking
and can be changed by turning the rotary knob.
4. Press
button

(Esc) to
cancel the change.
5. If you wish to adjust additional parameters, repeat steps 2…4.
6. Press
button
(Esc) to leave the parameter setting mode.
The factory setting for the control parameters can be reloaded via parameter P71, by
changing the value to "ON". Confirm by pressing the right button.
The display shows "8888" during reloading.
