Question About Weil-McLain Boiler 68
Honeywell Limit Control...

I have a Weil Mclain 68 boiler with tankless coil. Ever since my Honeywell limit control was replaced (it burned), I do not have hot water for at least two minutes. What is the correct limit control for this model boiler? I think the contractor may have either installed the wrong control or wired it wrong.

0 go online if you do not have the paperwork for this control most techs set the hi limit at 180-190 with your tankless coil set the low at 130-140 the low regulates the temp of your domestic water also set the differential at around 10 with these settings you should have hot water even if the thermostat is calling for heat hope this was useful
