Setting the eBUS address
for cascade mode
Whenoperating severalboilers(up to4 controlunitsR1) inconjunction
withacascadecontrollerKM,adjusttheeBUS addressoftheboilersin
accordancewiththetable,below.
YouadjusttheeBUSaddressbyholdingdowntheresetbuttonwiththe
systemoperating.After5seconds,thecorrespondingashingcodeappears
(inaccordancewiththetable)atthesignalring.Selectthecorresponding
eBUSaddresswiththeDHWtemperaturerotaryselector.Yourselectionof

InconjunctionwiththeKMcascadecontroller,between1and4R1control
unitscanbelinkedup.
Communication is realised via the two-wire BUS. Each boiler has an
eBUSaddressassigned.TheKMprovideseachboilerwiththemodulation
level(0...100%)andanenablecommand,uponwhicheveryboilermust
operate.
TheR1startsassoonastheKMissuesamodulationlevelgreaterthan
