Check in Menu A7 ( ¬ Chap. 7.4.4 ) that all the actua-
tors and sensors are connected properly and are wor-
king correctly.

> Select
Turn the left hand knob until Menu A7 is displayed.
At Component , select in sequence all the connected
modules that permit an actuator/sensor test.
At
Actuators , activate the actuators directly. You
can, for example:
drive a mixer in the
OPEN direction and check that it
is connected the right way round or
activate a pump and check that it starts up.
Only the activated actuator is active; all the other
actuators are "switched off" at this time.
At Sensors you can read the measured values from
individual components and check whether the sensor
is providing the expected value (temperature, pres-
sure, flow rate ...).
At
Heating Appliance you can start up the individual
boilers in the cascade and check that the components
are wired correctly.
If all the heating circuits and cylinders are fully pre-
sent and the parameters correctly set, confirm the
Installation completed? parameter in Menu A8 with
Yes .
i
Menu A8 only appears during the initial start-
up.
If further settings are required for the system configu-
rations, then:
Turn the left hand knob until Menu 8 is displayed.
In Menu 8 , enter the access code to enable the
Installer level.
If you now wish to check, set or optimise other parame-
ters, then note the following:
Information about operating controls, operating con-
cept, menu types, etc. can be found in Chapter 3.
The parameters you can set and optimise in the Ope-
rator level are described in Chapter 7.1. An overview
of these parameters can be found in the appendix
(
¬ Table 13.5 ).
The parameters you can set and optimise in the
Installer level are described in Chapter 7.3. An over-
view of these parameters can be found in the appen-
dix (
¬ Table 13.4 ).

6.3 Protecting the Installer level from
unauthorised access
b
Caution!
Material damage caused by inappropriate
changes!
Incorrectly set parameters can cause material
damage to the heating installation.
Only competent persons may set the parame-
ters in the Installer level.
After the initial installation, set an access
code to protect the Installer level from
unauthorised enabling.
Code level
8
enabling
Code number:
0 0 0 0
Standard Code:
1 0 0 0
>Adjust numeric character
Menu 8 completes the Operator level.
i
When the standard code is displayed, the ope-
rator can enable the Installer level after ente-
ring the standard code - 1000 - and change
the system-specific parameters.
After the initial installation, set a new access code in
Menu
C11 so that the standard code will no longer be
effective.
Make a note of the new access code before you save
it.
After the access code has been saved in Menu C11 , the
standard code will no longer be displayed in Menu 8 .
The Installer level is permanently protected from unaut-
horised access.
6.4 Data transfer
Data transfer only takes place if the heating installation
is fitted with the VRC DCF external sensor
(
¬ Table 1.1 , Part No.).
Depending on the conditions on site, it can take up to
15 minutes for all the data (outside temperature, DCF,
appliance status etc.) to be updated.
