I get questions like this a lot. "Can this Honeywell control replace this Honeywell control?" Or "Is this control a direct replacement for that one.” What you need to understand is Honeywell has made controls for a long time, they have never passed on the opportunity to make a new variant of a control and assigned it a new model number or given the same control different model numbers depending on what furnace or boiler manufacturer they were providing to as an OEM. So in most cases there are multiple Honeywell controls that essentially do the same thing. But to say that something is a direct replacement or just a replacement over simplifies things. You really need to understand the logic designed into the appliance and the control as the new control may have multiple logic pathways built into it depending on how it is wired and wire color codes will not necessarily be the same. In fact they probably won’t. So assuming I was familiar with the appliance in question and had the schematic, could I replace your control with this one? Yes I am pretty confident given my years of plumbing experience I could. Can you? I am sorry but I don’t know as I do not know the piece of equipment you are working on or your mechanical acumen.
This product works with certain oil burners. So it depends on if this is the right control for that burner not whether the burner is on a oil fired hot air furnace, oil boiler or oil hot water heater.
The control you are referencing is different. It is a oil burner cad cell relay, often times referred to as as and oil burner primary, However yours is equipped with supplemental 24 volt transformer which is most likely powering additional control circuitry.
