Question Question about Primary Oil Controller

We have an oil furnace, which is currently using a Honeywell #R8184A controller. This controller is a constant spark contoller.
My question is this, Are the newer controllers which are intermittent type compatable or not.
It is my understanding that on the older controller, the spark electodes fire the entire time the burner is on.
Is this how the intermittent type work too?

Almost all of the new primary controls shut down the ignition once the cad cell (flame sensing eye) detects flame or shortly thereafter. Here's the installation sheet for the Honeywell R7184 series of primary controls: https://customer.honeywell.com/resou...0s/69-1459.pdf

With the R7184, when you install it, you can wire it up for either continuous spark/ignition, or for such to stop once flame has been established. The instructions show how to wire, for both types.

With the even newer R7284, you can wire it up the same way as the R7184, or simply set the software option (it has an LCD display for setting options) of the spark/ignition to be continuous or not. The software option is "spark during run".

For continuous spark/ignition, the term is "intermittent". For when the spark/ignition shuts off after flame, the term is "interrupted".
