    He found the reset and bleed it and all is well until the next time he runs out of oil.

    I never heard of that model so I looked it up. I never knew HW made an integrated primary.
    When the Carlin EZ came out, they used a similar control by Phaylon but no programming. They didn't last long.
    Bringing the line volt right into the burner housing and making splices in there gets messy.

    @HVACNUT Bryant used them with their furnaces, for one. Actually the wiring isn't that bad. Usually the voltage comes from the board in the blower compartment. But that control, a little hard to find, is pricey.
