11 Main menu
11.1 Introduction
The
MENU
is reached by pressing the button on the
controller.
The main menu comprises:
•
OFF
Select this option if you wish to shut the water
heater down (10 "Shutting down") for a brief
period, 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 (11.3 "Switching to "ON mode"").
•
WEEK PROGRAM
Select this option to allow the water heater to
respond to demand only during pre-programmed
periods (11.5 "Week program"). 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 (11.10 "Extra period") of heat
demand will be fulfilled.
•
SETTINGS
Select this option to set (11.11 "Settings") the
language and the time. 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.
