What it is

The Viessmann coding plug 20160307 is a configuration plug supplied by Viessmann for use on the Vitodens 200-W Wb2B 19KW. It carries the coding values the appliance control reads to identify the boiler variant and its operating parameters. The plug is fitted to the control unit as part of the appliance's set-up.

Signs this part needs replacing

  • The boiler does not run correctly after the coding plug is missing, loose or damaged.
  • The control unit fails to read the appliance configuration.
  • The plug shows physical damage, corrosion or heat marking at its terminals.
  • The plug has been removed or replaced during a control unit change and the correct coding is no longer in place.

Before you order

  • Confirm the appliance model and serial number match the fitment listed for this coding plug.
  • Check the existing coding plug's printed number and compare it with 20160307.
  • Inspect the control unit connector for damage before fitting a replacement plug.
