my high is set at 180 but i have never seen it get this high. It runs around 140-150 I have never seen it above 150. I think circulate is set at a little above 100. When it draws cold water back and the temp falls circulater shut off then fires back up when temp is between 100-110 My water temp usually stays at 140
Well then thats fine.Its just I wanted to make sure.New baseboard radiation looks for 180 degree water,so your limit would be higher.
