Honeywell aquastat settings
Posted by Mark A. on December 25, 2002 at 14:41:28:
I have a Peerless WV-04-125-WPCT boiler with a Honeywell L8124 series aquastat. Since installation
of the boiler 8 years ago, the settings of aquastat have been HI of 180, LO of 160 and DIFF of 10.
From what I understand about the operation of the differential, for winter use it should be set at 20 or 25,
not 10. 10 is where it should be for warm weather. Can someone confirm this?
Thank you, Mark L.
