Adjustable values –overview (→Page 14)

4 Operation

4.1 Starting up the product

4.1.1 Opening the isolators

1. Ask the competent person who in-

stalled the product to explain to you

where these isolators are located and

how to handle them.

2. Open the gas stopcock fully.

3. Check that the heating installation flow

and return service valves are open, if

such service valves are installed.

4. Open the cold-water isolation valve.

To check, you can turn on a hot water

tap and see whether water is escaping

there.

4.1.2 Switching on the product

▶Switch on the product via the main

switch installed on-site.

4.2 Basic display

The filling pressure of the heating installa-

tion and the operating mode are shown in

the display's basic display.

To return to the basic display:

–Wait more than five seconds without

pressing any buttons.

If a fault message is present, the basic

display switches to the fault code.

4.3 Checking the heating system

pressure

1. Once a month, check that the pressure

in the central heating system, which

is displayed on the user interface, is

between 0.05 MPa and 0.27 MPa

(0.5 bar and 2.7 bar).

◁If the filling pressure is correct, no

action needs to be taken.

▽If the filling pressure is too low, add

more water to the heating installa-

tion.

Note

If the heating flow temperature

is shown in the display, press

and hold the and buttons

at the same time for longer than

five seconds, or temporarily

deactivate heating mode in

order to display the pressure.

2. Fill the heating installation. (→Page 10)

4.4 Filling the heating installation

Caution.

Risk of material damage due

to heating water that is ex-

tremely calciferous or corros-

ive or contaminated by chem-

icals.

Unsuitable tap water damages

the seals and diaphragms,

blocks components in the

product and heating installation

through which the water flows

and causes noise.
