Have a new WGO-4 with Hydrolevel 3150 aquastat. While the burner is running, about every minute (possibly exactly), the burner relays click off for about 1/4 second (just enough to interrupt the flame) then back on. Powering the burner circuit directly stops the problem.
I reseated the probe, but no change. I assume I just have a bad unit, but was looking to see if anyone has seen this happening. Temped to just go back to the mechanical aquastat I have on hand.
also, hi temp set for 180 with -20, and low point turned off (cold start).
