VFC 15-150 and VFC 45-225
2.4.1 User setup
The occupant has access to a number of
practical settings. The most meaningful
include adjustment of the indoor
temperature target plus the temperature
setback and occupied / unoccupied
modes. The User Menu also provides
access to the time & date fields,
provides the means to toggle between
C° / F° plus allows adjustment of the
screen image itself (“
Contrast
Adjustment
”).
2.4.2 Installer Setup
The installer has access to all “
User
”
adjustable fields plus a much wider
selection of inputs. Loads can be
declared and configured, with
temperature settings appropriate to the
characteristics of the heating system.
Key issues here are selection of
appropriate boiler supply temperature
criteria for the type of emitter, and the
establishment of practical temperature
differentials – e.g. DHW tank target vs.
boiler supply.
A record of the service history is also
available for onscreen access.
2.4.3 Advanced Setup
This access level is set for the sole use
of factory representatives and is
permanently password protected.
2.4.4 Advanced Diagnostics
Not an access level, this field allows a
view into detailed sensor readings and
operating parameters such as fan rpm.
This screen is useful for advanced
troubleshooting of pressure sensors, etc.
2.4.5 Passwords
A Password access feature is loaded on
the controller, for use in situations
where there is exposure to unauthorized
and / or uneducated adjustment. The
installer is encouraged to consult with
the user to determine the need for
ongoing access to settings. In risk
situations, the password feature can be
invoked by selecting “
Password
On/Off”
and toggling to “
On”
in either
or both of the User and Installer menus.
Pre-set passwords are used: for the User
the code is “11111” followed by “enter”
A common “installer” code is also used,
to ensure continuing access even with a
change in service personnel.
