Advanced Setup - IBC VFC 15-150 Manual

BOILER SYSTEMS AND OPERATION
VFC 15-150 - VFC 45-225 MODULATING GAS BOILERS
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 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.

2.4.4 Advanced Setup

this access level is set for the sole use of factory representatives and is
permanently password protected.
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. Contact iBC for access to this password.
