Activating the shift-load cylinder

Applicability:

Product with integrated hot water generation and shift-load

cylinder

To activate an

actoSTOR

shift-load cylinder which is also

connected, you must switch on cylinder charging on your
product.

To do this, activate Comfort mode (Comfort mode
(

Page 8)).

The symbol " " appears in the display.

Set the hot water temperature.

Conditions

: Cylinder charging switched on

Hot water temperature: 50 … 65

Danger!
Risk of scalding!

The products are equipped with an automatic

anti-legionella function: If the temperature in

the shift-load cylinder falls below 50 °C for

24 hours, the cylinder is heated up to 70 °C

once.

Please note when drawing water that it

can be very hot.

If you want to switch off the "Anti-legionella function", you
should ask a competent person.

If you want to switch off cylinder charging, deactivate
Comfort mode "Switching Comfort mode on and off
(

Page 8)".

Conditions

: Cylinder charging switched off

Hot water temperature: 35 … 65

The cylinder is not maintained at a specific temperat-
ure. If you draw off the water, the product switches on
and, in this case, only operates as an instantaneous
water heater.

Switching off the product's functions

4.13.1 Switching off heating mode (Summer

mode)

1.

To switch off heating mode without switching off hot
water generation, press

( ).

The value of the heating flow temperature appears
in the display.

2.

Use the

button to set the heating flow temperature to

Heating off

.

3.

Confirm by pressing

.

Heating mode is switched off.

The

symbol appears on the display.

4.13.2 Switching off hot water generation

Applicability:

Product with hot water generation through external domestic

hot water cylinder

1.

To switch off cylinder charging without switching off
heating mode, press

(

).

The set hot water temperature flashes in the display.

2.

Use the

button to set the hot water temperature to

Heating off

.

3.

Confirm by pressing

.

Cylinder charging is switched off.

Only the frost protection function for the cylinder
remains active.

4.14

Guaranteeing the correct filling pressure of
the heating system

4.14.1 Checking the filling pressure of the heating

installation

Note

To ensure that the heating installation operates
smoothly, the filling pressure when the heating
installation is cold must be between 0.1 MPa and
0.2 MPa (1.0 bar and 2.0 bar) or lie between the
two dashed lines in the bar graph display.

If the heating installation extends over several
storeys, a higher filling pressure may be required
for the heating installation. Ask a competent per-
son for details.

In addition, the

symbol appears after approx.

one minute.

If the filling pressure in the heating installation
falls below 0.05 MPa (0.5 bar), then the product
switches off. The display alternates between the
fault message

F.22

and the current filling pres-

sure.

1.

Press

twice.

The values for the current filling pressure and for the
minimum and maximum filling pressures appear in
the display.

2.

Check the filling pressure in the display.

1 / 2

System pressure: 0.1 … 0.2 MPa (1.0 … 2.0 bar)
The filling pressure is in the intended pressure range.

2 / 2

Filling pressure: < 0.08 MPa (< 0.80 bar)

Fill the heating installation. (

Page 10)

If you have topped up the installation with suf-
ficient heating water, the display automatically
disappears after 20 seconds.
