Extension module AGU2.550A109 is required for each boiler. Set the dip switch to 1. The parameters in the LMS
are set to acknowledge module No.1 as the VFC outputs
Note: A maximum of three extension modules can be accommodated per boiler. Using this option reduces the
number of addition heating circuits that can be controller by the boiler from three to two.
