4.1 Operating concept

The display switches on when you switch
on the product or press a button. You can
now configure settings by pressing the
buttons again.
When you switch the product off using the
on/off button, the display goes out (the
frost protection function is active for as
long as power is supplied).

Both selection buttons have a soft key
function, i.e. their function can change.
If, for example, you press the left-hand
selection button

in the basic display,

the current function switches from

(Do-

mestic hot water temperature) to

(Back).

Adjustable values are always displayed as
flashing.

You must always confirm a change to a
value. Only then is the new setting saved.
You can press

to cancel a procedure at

any time. If you do not press any buttons
for longer 15 minutes, the display returns
to the basic display.

4.1.1 Basic display

The basic display shows the current
product status.
To return to the basic display, press the

button. If you do not press any buttons

within three minutes, the display becomes
dark and automatically switches back to
the basic display.
If an error message appears, the error
code will be shown on the basic display.
The available functions vary depending on
whether:

A room thermostat is connected to the
product or not

A domestic hot water cylinder with tem-
perature sensor is connected to the
product or not

4.1.2 Operating levels

The product has two operating levels:

The operator level shows the most im-
portant information and offers set-up
options which do not require any special
prior knowledge.

Specialised knowledge is required in or-
der to use the installer level (access for
competent persons). This is therefore
protected by an access code.
