The operating parameters can be modi ed using the front keypad, and are divided into two families: frequent use parameters
(type “F”) and con guration parameters (type “C”). Access to the con guration parameters is protected by a password that
prevents unwanted modi cations or access by unauthorised persons.
How to access type “F” parameters (frequent use):
press PRG for more than 5 seconds (if an alarm is active, the buzzer is muted  rst of all), the display shows the code of the  rst
modi able type “F” parameter.
How to access type “C” parameters (con guration):
1. Press PRG and SET together for more than 5 seconds; the display will show the number “00”,
representing the password prompt;
2. press or until displaying the number “22” (the code of the password allows access to the parameters);
3. con rm by pressing SET; the display will show the code of the  rst modi able type “C” parameter.
4.1 Modifying the parameters
After having displayed the parameter, either type “C” or type “F”, proceed as follows:
1. press or suntil reaching the parameter to be modi ed. When scrolling, an icon appears on the display representing the
category the parameter belongs to. Alternatively, press PRG to display the menu of parameter categories, which is used to
quickly access the family of parameters to be modi ed;
2. scroll the menu with the and buttons; the display shows the codes of the various categories of parameters (see the
“Summary of operating parameters”), accompanied by the display of the corresponding icon (if present);
3. when having reached the desired category, press SET to move directly to the  rst parameter in the category (if there are no
visible parameters in the selected category, pressing SET will have no e ect);
4. at this stage, continue to scroll the parameters, or return to the categories menu by pressing PRG;
5. press SET to display the value associated with the parameter;
6. increase or decrease the value using the or button respectively;
7. press SET to temporarily save the new value and return to the display of the parameter code. Repeat the operations from
point 1 or point 2;
8. if the parameter has sub-parameters, press SET to display the  rst sub-parameter;
9. press or to display all the sub-parameters;
10. press SET to display the associated value;
11. increase or decrease the value using theor button respectively;
12. press SET to temporarily save the new value and return to the display of the sub-parameter code;
13. press PRG to return to the display of the parent parameter.
Note: the controller features unit parameters that cannot be displayed and modi ed on the user interface, and operating
parameters. The latter can be selected as frequent use (F), con guration (C) or not visible on the user interface. To modify the unit
parameters and the visibility of the operating parameters, use the programming key code PS0PZKEY00/A0, IR0PZKEY00/A0 and
the IR0PZPRG00 or VPMSTDKY10/20 tool.
4.2 Storing the new values assigned to the parameters
To de nitively store the new values of the modi ed parameters, press PRG for more than 5 seconds, thus exiting the parameter
setting procedure. All the modi cations made to the parameters, temporarily stored in the RAM, can be cancelled and “normal
operation” resumed by not pressing any button for 60 seconds, thus allowing the parameter setting session to expire due to
timeout. Important: if the programming session ends by timeout, the clock parameters will not be reset, as these parameters are
saved immediately when entered.
If the instrument is switched o before pressing PRG, all the modi cations made to the parameters and temporarily saved will be
lost.
4.3 Classi cation of the parameters
The parameters, as well as being divided by TYPE, are also grouped into logical CATEGORIES identi ed by the initial letters or
symbols. The following table lists the categories and the corresponding letters.
