LCD display
Home page
The unit may display the default measurement pages when the Home button is pressed (starting from any measurement page) or after no
operation has been performed for five minutes, if the screensaver is enabled and the screensaver type is set by UCS to “Home page” (default
value).
Notes: if you select a page that is not available in the set system, the unit displays as its home page the first available page. In MID models the
home page cannot be changed and displays the active energy meter.
Backlight
The WM15 unit is equipped with a backlight system. You can set whether the backlight shall always be ON or whether it should automatically
switch off after a given interval has elapsed since a button was pressed (1 to 60 minutes).
Screensaver
If the SCREENSAVER function is enabled (default setting), after 5 minutes have elapsed since a button was pressed the unit will display the
home page if the screensaver type is “Home page” (default setting), or it shall activate the slideshow function, which displays the selected
pages on a rotating basis
Notes: the screensaver type and the slideshow function with the relevant pages can only be set up through the UCS software or the UCS
Mobile app. In MID models the screensaver setting is “Homepage” and cannot be changed.
Page lter
The page filter makes it easier to use and browse the measurement pages. When you use the / buttons, the unit shall only display
the pages you are most interested in, which can be selected through the UCS software or the UCS Mobile app.
Note: to display all the pages without using the UCS software or app, you can disable the page filter from the SETTINGS MENU (DISPLAY →
PAGE FILTER → OFF). By default, the pages included in the filter are: 1, 10, 13, 16, 17, 21, 22, 26, see “Measurement pages” on page 14.
Restoring the factory settings
Restoring the settings using the RESET menu
From the RESET menu you can restore all the factory settings. At start-up the QUICK SET-UP and WIRING CHECK menu shall be available
again.
Notes: meters are not reset. In MID models you cannot reset the CT current transformer ratio (CT RATIO).
Restoring the settings using the reset button
Press for at least five seconds the reset button (located near the current inputs) to access the menu, restore all the factory settings and reset
all meters (total and partial).
Note: in MID models the reset can only be performed if the energy meter has not exceeded 1 kWh. Before sealing the terminal, you can then
correct any CT current transformer setting errors (CT ratio), reactivating the MID programming menu at the next switch-on.
