Welcome! Here are the website rules, as well as some tips for using this forum.
have a buderus conmod installed in older home with radiantheat.a couple runs are a little long @ 250-300'. along with that i still have some heat loss being an older home and working on getting rooms completed and insulated proper. when zones call for heat i've noticed that the heat loss out weighs the heat coming from the floor and as a result the temp.stays a degree or two below setting. therefore room can't come up to temp and system runs longer than normally would. cozy floors but air temp is cool say at 65-67 when set at 68 depending on outside temp.the am10 reset "tells" the boiler at what temp to heat water? varying from 120 to 180. my ? is this. what would happen if i disconnect the am10. would boiler heat water temp to max, say 180 all the time? or would it go into default code? my theory being if temp remained at 180 floors heat up more maybe reaching set temps more readily? or just get house tightened up and reduce heat loss . any info greatly appreciated.
