Standard display
The standard display shows the following:
Day of the week, time and current charge level (calcu-
lated using the core sensor). The more heat has been
stored, the more black will show in the bar (in this
case 0%).As soon as any button or rotary knob is
activated, the display will be backlit. If you want to
backlight the standard display, press the OK, + or –
buttons, since these do not directly execute an action.
The backlighting will be deactivated if the display is
idle for around 15 seconds
Charging
By turning the left-hand rotary knob (target charge
level), the target charge level can be changed. It will
then be stored as the new control variable. The dis-
play utilises a bar (0 to 100%) in the LCD display. To
help orientate the user, the bar is marked every 25%.
Discharging
By turning the right-hand rotary knob (target room
temperature), the target room temperature can be
changed. It will then be stored as the new control
variable. Settings of between 5°C and 30°C are avail-
able and will be shown in the LCD display.
Child-proofing
To avoid settings on the storage unit being acciden-
tally changed (when cleaning, or by children playing),
you can activate the child-proofing device.
If you press the OK button for 4 seconds, the 'Button
lock' indicator will appear at the top left of the display.
This setting means that the control unit will not exe-
cute any manual functions. Neither the buttons nor
the rotary knobs will be active. If it is necessary to
readjust the rotary knobs while the buttons are locked,
and the lock is de-activated, the control unit will natu-
rally accept the new values. However, this will also be
shown immediately. This means that, once the lock
has been deactivated (by pressing the OK button for 4
seconds), the adjusted value (e.g. room temperature
30°C) will be displayed. If a rotary button has not been
adjusted, you will only see the 'Button lock' message.
