Vaillant ecoTEC plus VUI Series Installation And Maintenance Instructions Manual page 35

9.4 Deactivating standby mode
Note
If the product is connected via a fixed connection,
the product is switched on as soon as the power
supply is established.
▶
Press the on/off button on the display.
◁
The display shows the basic display.
9.5 Running through the installation assistant
The installation assistant is launched when the product is
switched on for the first time.
After starting the installation assistant, all of the product's re-
quirements are blocked. This status remains until the install-
ation assistant is completed or cancelled.
▶
Close the gas stopcock before running the installation
assistant.
▶
Ensure that the gas stopcock remains closed until the
installation assistant has finished running.
▶
Once the installation assistant has ended, open the gas
stopcock and switch on the heat demand.
You can restart the installation assistant at any time.
9.5.1 Setting the language, date and time
▶
Set the required language, date and time, and confirm.
9.5.2 Filling the installation
Filling mode (check programme P.008) is activated auto-
matically in the installation assistant for as long as the filling
mode appears on the display.
▶
Start the filling programme and fill the heating installation
with heating water. Observe the specifications for treating
the heating water.
▶
Wait until the programme has ended.
9.5.3 Setting the hydraulic operating mode
Note
Different hydraulic operating modes are available
depending on the product variant.
▶
Set the hydraulic operating mode and confirm. You can
adjust the operating mode again at a later point via the
diagnostics codes. (→ Section 10.3.5)
▶
Set the available pressure.
9.5.4 Setting the gas type
▶
Set the gas type that is available on-site and with which
you want to operate the product, and confirm.
9.5.5 Setting the air/flue pipe type
▶
Set the correct air/flue pipe type with which the product
was installed, and confirm.

9.5.6 Contact details
▶
If required, store your telephone number and your com-
pany name in the Appliance config. (max. 16 digits/no
blank spaces). The end user can view the telephone

In addition to the installation assistant, you can also call
up the following functions for start-up, maintenance and
troubleshooting:
Check programmes (→ Appendix G)
Actuator test (→ Appendix H)
9.7 Guaranteeing the system pressure
If the heating installation covers multiple storeys, higher val-
ues than the permissible operating filling pressure may be
necessary for the filling pressure in order to prevent air from
getting into the heating installation.
This static height is the height difference in metres between
the heat generator and the highest heating area for a cellar
installation or the lowest heating area for a rooftop control
system.
–
Permissible operating filling pressure: 0.1 to 0.2 MPa (1.0
to 2.0 bar)
The operating filling pressure must be increased by
0.01 MPa (0.1 bar) for every metre of the determined static
height. The filling must take place via the intake side of the
heating pump, usually the return.
Once the maximum filling pressure is reached, the product
signals the excess pressure using a flashing value on the
display.
– Maximum operating filling pressure: ≤ 0.25 MPa
(≤ 2.50 bar)
Once the filling pressure reaches the minimum filling pres-
sure, the product signals that the pressure is low using a
flashing value on the display.
–
Minimum operating filling pressure: < 0.08 MPa
(< 0.80 bar)
Once the filling pressure reaches the operating limit filling
pressure, the product shuts down and the display shows
fault code F.022.
– Operating limit filling pressure: ≤ 0.03 MPa (≤ 0.30 bar)
▶
When you fill or top up the heating water, start the purge
programme (→ Section 9.10).
