3.14 Control parameters
A number of control parameters can be readjusted to optimize control performance.
This can be done on the thermostat via HMI or via commissioning / operating tool.
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, see page 51.
The control parameters are assigned to 2 levels:
• "Service level", and
• "Expert level" including communications, 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 be
adjusted any time.
Change parameters at the "Expert level" carefully, as they impact the thermostat’s
control performance and functionality.
3.14.1 Parameter setting via local HMI
1. Press buttons + and – simultaneously for 4 seconds.
Release and press button + again within 2 seconds until the display shows "P01".
Continue with step 2.
1. Press buttons + and – simultaneously for 4 seconds.
Release and press button – again within 2 seconds until the display shows "P01".
2. Repeatedly press the + or – button to select the required parameter.

3. Press + and – simultaneously. The current value of the selected parameter
begins to flash, allowing you to change the value by repeatedly pressing + or –.
4. The next parameter is displayed when you press + and – again simultaneously.
5. Repeat steps 2 to 4 to display and change additional parameters.
6. Press + or – until "End" is displayed, and then press + and – simultaneously to
save the change and exit parameter entry mode.
The factory setting for the control parameters can be reloaded via parameter P71,
by changing the value to "ON", and confirming by pressing buttons + and –
simultaneously. The display shows "8888" during reload.
