Worked perfect as a replacement for my old device. Got a quote for about $3500 to fix / upgrade my old system but this replacement piece did the job perfectly.

Transformer hums and both coil sets were way hotter than older 20 year old identical Honeywell original RA832A.This replaces an identical model installed for a basement zone added 2002.The 1962 versions next to it are still working flawlessly.Started having an issue of intermittent signal to ignite boiler on original even when boiler was cold, yet pump circulator was running. Just pulling off the cover or sliding it would trigger the boiler. Worked without hiccup for 20 years but it was not reliable no matter what adjustments and contact cleaning was done.New one is working every time, so I can stop worrying about it. Came in earlier than quoted which was nice too.

Great product and perfect replacement, we haven't had any heat in almost 2 years. I replaced my old mercury themostat with a Honeywell T5 digital programmable. I thought the themostat was the issue but actually it was a the Transducer. My mother's friend had replaced this a year ago and it sort of fixed the issue, but come to find out when I investigated the heat issue 2 years later. The part was the wrong one, so I bought the correct one and now my heat works perfectly. Thanks Honeywell, great products nearly 100 years later.

I purchased one of these over 20 years ago to control the pumps in my hydronic heating system. The wiring diagram was very intuitive, so installation was fast and easy. Since the initial insertion, many pumps have come and gone, and this relay has outlasted them all, flawlessly turning my system on and off without a hiccup. After a recent series of power surges, I thought I better get a back-up relay just in case old faithful were to burn out. It now sits in the box next to the original, ready to service my needs at a moments notice.

Perfect! Exactly the same wiring diagram as my decades old one.
