Communication to the boiler takes place
using a 2-core bus cable (eBus). All eBus
connector plugs are designed to allow at
least 2 x 0.75 mm

(recommended) per
connection terminal. This means that the
wires can be swapped without impairing
communication (fig. 10.1). Also follow the
instructions for the boiler. Do not
remove the jumper between terminals 3
and 4 on the boiler.
