VFC 15-150 - VFC 45-225 MODULATING GAS BOILERS
2.3.2 LCD Display
Uponpower-up,theLCDscreeninitiallyashesasoftwarereleasenumber
then switches to a Standby- display mode, showing real time data plus key
temperature target settings.
Whenthereisacallforheatfromanyload,thatloadisidentiedattheStatus
line (e.g. Heating – RFL (for radiant oor) in place of Standby). The Target
temperature for the relevant load is conspicuously displayed while that load is
being handled.
NOTE: The Status line displays those loads that are heating or calling for
heat. In this instance (“Heating 3DHW”), Load 3 has been set up as DHW and
is actively heating, with no other loads calling for heat. If you saw (“Heating
3DHW C:1RFL”), it would indicate Load 3 DHW is actively heating, while Load
1 (Radiant Floor heating with Reset) is shown as requiring heat but awaiting its
turn. If a third load has been implemented and is also calling, the Status line
display would expand to show the relevant details.
LEGEND:
• RFl: Radiant Floor with Reset
• CIR: Cast Iron Radiators w/ Reset
• BBd: Baseboards w/ Reset
• AIR: Air Handler w/ Reset
• StP: Set Point
• DHW: Domestic Hot Water
Other information is accessible using a menu based system – described in the
following sections.
ACCESS LEVELS
The controller provides for the display of further information (via the Load
Status Screen) plus three levels of access for the adjustment of control settings.
Thisisdonetosimplifythecontrolinterfacefortheuserwhileretainingeld
access to the full functionality of the system for the appropriately trained
heating professional. The split access feature offers a layer of security against
adventurous“ngertrouble”,includingaccidentaladjustmenttosettingsthatcould
leadtoinefcientoperation(e.g.excessivecycling)ordangerousconditions.
To access the Main Menu, touch any key. Move the cursor up or down using the
top and bottom keys.
The Load Status Screen offers a comprehensive summary of all settings and
actual readings for each heating load, eliminating a need to jump between
screens while doing an extended watch of boiler operation.
NOTE: where the word “more” is displayed at the bottom or top of a screen, it is
possible to see more lines by moving the cursor in that direction.
