* Note. that production boiler PCB’s are factory pre-
set to operate for boiler range and output, but when
ordering Primary PCB as a spare, an additional Boiler
Chip Card (BCC) MUST also be purchased for your
specific boiler range and output.
Check boiler serial letter code on data plate to obtain
correct BCC.
