KWE P/N 394038 Versatronik 505 and 505D BACIP Gateway V1.2 February 2014 Technical information subject to change without notice
Additional Alarm/Fault Information
Viessmann controls show fault codes in
hexadecimal format to conserve screen space
on the user interface of the boiler and system
controls. The Versatronik 505 gateway uses a
SNVT_count variable which is usually
displayed in decimal format.
The base-format in which this fault can be
displayed depends on your BMS software.
This example shows how to display this fault
code in hexadecimal, and Text format in
Niagara AX.
To display in hex, you can use the KitControl -
> Util “Numeric Bit And” object’s mask input.
To display the equivalent fault text value, you
can use the KitControl -> Conversion
“Numeric To Enum” object and type out the
enum range for all Viessmann error codes.
These values can now be displayed on a px
webpage by pointing a Bound Label to the
appropriate slot values.
