3/3 Identify the wires
Identify the power supply
terminals with 220/230V,
usually labelled P/N or L/N.
Connect the boiler adaptor's
blue wire to the N terminal of
the boiler. Connect the brown
wire to the P or L terminal.
If some wires are already
connected to those terminal,
leave them in place.
See the Installation Troubleshooting p. 30 for more help.
