ure

–Cancelling the change to a set

value or activating an operating

mode

–Calling up a higher selection

level in the menu

–Setting the heating flow tem-

perature, filling pressure of the

heating system or activating the

heating mode

–Confirming a set value or activ-

ating an operating mode

–Calling up a lower selection

(press twice)

4 Function

10 Operating instructions ecoTEC pure 0020258017_00

Button Meaning

+–Calling up the additional func-

tions

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

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.

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.
