4.3 Main menu
The MENU is reached by pressing [ ] on the operator interface.
The main menu comprises:
OFF
Select this option if you wish to turn off the water heater for a short period (see
section 4.2), but do not wish to drain it. In this mode, the frost protection is active.
This prevents water from freezing in the water heater.
ON
In this mode, the water heater continually responds to the hot water demand (see
section 4.3.2).
WEEK PROGRAM
Select this option to allow the water heater to respond to demand only during pre-
programmed periods (see section 4.3.4). Outside those periods, only frost protection
is active.
EXTRA PERIOD
Select this option to overrule OFF mode or PROG mode (i.e. Week program) so
that a single temporary period (see section 4.3.9) of heat demand will be fulfilled.
SETTINGS
Select this option to set the language and the time (see section 4.3.10). You can also
use this option to display the regulation interval (temperature), and the ignition and
working speeds of the fan.
Note
If you fail to make any selection with the main menu open, then after 30 seconds, the
water heater will automatically return to the mode it was previously in.
4.3.1 Notation conventions for menu-related instructions
The MENU [ ] of the controller is divided into submenus. For example, SETTINGS is one
of the functions reached from the main menu. The menu SETTINGS is itself divided into
sub-menus. For example, LANGUAGE is a sub-menu of SETTINGS.
So, for example, to select menu LANGUAGE, this manual employs the following
convention:
[ ]: SETTINGS | LANGUAGE
Confirm with [ENTER].
This means:
[ ]: Activate the main menu with [ ].
SETTINGS: Using [ ] and/or [ ] to go to SETTINGS and confirm with [ENTER].
LANGUAGE: Using [ ] and/or [ ] to go to LANGUAGE
Confirm with [ENTER]. After pressing [ENTER], you will have activated sub-menu
LANGUAGE.
