R8184G to a R845A.
Currently have a R845A going to a stack relay R117A which I want to replace with a R8184G. Also have an old minneapolis honeywell external mounted LX model Aquastat in the loop.
Can I replace the R117A with a R8184G so I can then install a photocell C554A, and if so how should I terminate? Any schematics would be appreciated.
