Oil Burner control box

[maltaron]

Are LOA21 and LOA24 compatable? I have a Minor 1 burner with a LOA24 and a spare burner with a LOA21. Could the 21 replace the 24 in the unlikely event of a failure.

Un plug both control boxes, and have a look at the wiring diagram on the back of each one and compare, I think the LOA21 is a single stage box, whereas the LOA24 is a 2 stage box.

LOA21 will probalby only show V1 on the diagram
LOA24 will probalby show V1 & V2 on diagram
Good news cos your Minor Burner is only a single stage burner, so the boxes should be a straight swap

Many Thanks Boilerman2. That means I can keep our Stanley cooker running until my serviceman can come round.

Danfoss BHO 61 will also substitute
