Display and knob
The controller’s display can be viewed through the glass of the viewing aperture on the front panel of the appliance.
Upon activation, all display’s LED’s light up, and then the name of the controller displays. Subsequently (if the on/off command
switch is set to ON), the appliance begins to operate.
During correct operation the display shows, alternately, the following information: outlet water temperature, inlet water tempera-
ture, and the difference between the two water temperatures (see Table 4.2
→
15).

HOW TO ACCESS THE MENUS
▶
To use the knob with the special key supplied with the appliance:
You will need: the appliance's electrical power switches set to "ON"; the controller's display sequentially shows the operat-
ing data (temperature, delta T) regarding the current mode (e.g.: heating) and any active operating codes ("u/E...").
1.
Remove the front panel by removing the fixing screws.
2.
Remove the cover of the electrical panel to access the knob.
3.
Use the special key through the hole to operate the knob and access the controller’s menus and parameters.
4.
To display the menus just press the knob once: the display shows the first menu: "0." (= menu 0).
5.
The display shows “0.”. To display the other menus, turn the knob clockwise; The display will read, in order: "1.", "2.", "3.", "4.", "5.",
"6.", "7.", "8." and "E" (see 4.1
→
14).
6.
To display the parameters in a given menu (for example, menu 0), turn the knob until it displays the menu in question (in the
example: "0.") and press the knob: the display will show the first of the menu’s parameters, in this example "0.0" or "0.40" (=
menu 0, parameter "0" or "40").
7.
In the same way: turn the knob to scroll through content (menus, parameters, actions), press the knob to select/confirm the
content (access a menu, display/set a parameter, execute an action, quit or return to the previous level). For example, to quit
the menus, turn the knob to scroll through menus "0.", "1.", "2." etc. until the controller displays the quit screen "E"; now press
the knob to quit.
In the case of menus 0 and 1, the user can view any parameter. For how to access to menu 2, refer to Paragraph 4.3
→
15. To
set the parameters of me nu 3, refer to Paragraph 5.9
→
29. The other menus are not for the User: the information in these
menus is dealt with in the sections dedicated to the installation technician or Robur TAC.
The special key allows the knob of the electronic board to be operated without opening the cover of the electrical panel, so
that operators are protected from live components. When the necessary settings have been completed, put away the special
key, replace the cap on the aperture of the electrical panel and refit the front panel of the appliance.
