New R7284 no ignition

I just swapped out to a R7184B for a R7284 resideo oil primary control. I have attached all the wires which have been color-coded identically to the original controller. However, when I call for heat, I get no ignition. I know all the wiring is correct because the original well controller still works however, the new one does not ignite at all so I wonder if there is a setting I am missing, I have attached some pictures. Please let me know if anybody has suggestions. This is an Beckett oil hot air furnace.

Never mind, I figured it out. I needed 120 V going to the limit connection on the new thermostat. Now works like a charm.

Welcome to the forums.

The two units appear to have the same exact terminals in the same place.
It would have been nice if you had taken a before picture with the old module.

The only issue I'm coming up with is a possible required wire on the limit terminal.
The diagrams are showing a limit switch or jumper from L1 to limit.
Is it possible the black wire was on limit instead of L1 ?

On edit: Good job. I had been checking into this for the last half hour.
