How to range rate ATAG ic boilers

[@andrewriley4204]

Good video 😊 Quick question...
Are you doing this on a Gen' 3 model ? I ask as there's a chart or table in the M.I's that should help. It matches kW to the relevant %

So this boiler doesn't modulate on its own and has to be lower down the number manually?? 😮
