Relays started sticking on my 38+ year old R8184G 4009 on a Carlin 100 CRD. Cleaned once but faulted again after 3 days, cleaned again and needed a reliable fix. I have Franken Controls based on a 70 yr old install of a Burnam Coal/ Oil, Steam or HW boiler with 2 added zones w/ a Taco 503 in 2000. Had a problem 2 yrs ago and 2 boiler techs were stumped. Fortunately fixed w/ a $25 transformer patched in but I had to figure it out. So, I was worried that I would have to get a direct replacement of the R8184G 4009 for $70 more than this R7284 unit and 2 weeks from Amazon. This unit wasn’t supposed to arrive until next week. Just in case, I did find a R8184G 4009 at the “Big Orange†but it was $180 so was hoping this would come in time for the weekend and work out. It came in 2 days!I read Joe’s instructions and mostly followed them. I was nervous about tying both the red and black terminals to the 120 hot so first tried it w/o the red connected. No-Go.Connected the red and all was well. I did connect the igniter (blue) and Motor (orange) separately vs ganged together as my R8184G 4009 had done. Also ran separate neutrals vs ganging them all w/ a wire nut as was done on mine before. Setup was easy thanks to Joe and having the CAD cell display and diagnostics makes it look like it’s at least from the late 20th century vs. beginning of it. It was also an inexpensive fix at the end, the R8184G 4009 can go back to HD. I did have constant 120V to the jct box so did not have to run a line as others have.Thank you Joe and others for the great info. Now I can travel this weekend in peace not worrying about a cold house.

Bought to replace an old, failed R8184G. So far, seems like a huge upgrade.Instructions weren't the best, they seem to be targeted at someone with a significant amount of HVAC experience. Make sure to verify whether you have intermittent ignition and to wire properly based on the diagrams -- it's not 100% clear.The status display was amazingly helpful in troubleshooting a thermostat issue.All in all, cheaper and superior option to the older model ignitions.Pros:* Wiring now uses quick connect spade terminals. Wires are included for every terminal* Truly universal ignition -- can configure it for any number of options to replace nearly any older ignition model* Display provides a ton of help troubleshooting thermostat problems* Shows resistance output from safety sensor cell to help in troubleshooting ignition issues related to the photosensorCons:* Manual isn't as complete as it could be -- if you're familiar with HVAC and wiring, you'll be fine, but it leaves something to be desired* Unit is much wider and taller than older Protecotrelay ignitions -- clearance could be an issue depending on your furnace layout. Make sure to measure before purchase to make sure it won't be an issue. I needed to move my fan power supply to make enough clearance roomIf you need to replace an older ignition, don't buy the older ignition. Buy this. It's an upgrade in every way.

I replaced a failed R8184G 4009 with this unit, and this works perfectly.I replaced the R8184G on my Beckett oil furnace with this for several reasons:1. R8184G failed.2. R8184G wasn't available locally within 3 days in the dead of winter. Even my local heater technician didn't have one on hand. If he *WOULD HAVE* had it, he would have charged me over $500 to install this unit!! (It took about 10 minutes to install and 30 minutes of trial and error to get the menu settings correctly configured)3. This was actually CHEAPER!4. I could get this delivered in about 14 hours, ordering it at 6:30PM on Monday night. It arrived by 8AM the next morning. With free Prime shipping.Since the R8184G is a 3-wire unit, this took a little figuring out to hook it up correctly, then some more figuring to set the menu up correctly.Wiring:Black AND red wire on R7284 connected to where the black wire used to go on my R8184.White wire on R7284 went where white wire used to go on R8184.Orange wire on R7284 went where red wire used to go on R8184.Yellow CAD wires on R7284 went to same yellow wires that were connected to the front of the R8184.My thermostat wires from the front of the R8184 went to the front TT terminals on the R7284.Menu settings:I originally tried to use some of the new fancy settings on the R7284. If upgrading from the R8184, don't try to use those settings. You would have to change the wiring for it to work. It caused me several hard lockouts to learn this lesson.Final working menu settings:Valve On Delay: 0 secondsIgnition time: 45 seconds matches the R8184G. THIS one you can change if you prefer.Burner Off Delay: 0 secondsTT Configured: NoSpark In On Dly: NoSpark During Run: NoAllowed Resets: Your choiceAppliance Type: FURN (for my oil furnace)Show Diagnostics: Your choiceInstaller Setup: QuitRe-Baseline: YesIt's working perfectly for me and I have blessed heat again. The replacement was very easy once I figured all the connections and settings out.

This R7284U-1004 control is a nice improvement over the old Honeywell R8184G primary control I had previously on our oil fired boiler. Installation was fairly easy, except that I needed to pull another single #14 THHN wire through the flexible metal conduit that runs to the burner junction box to provide a constant 120V power supply to this new control, which is in addition to the existing switched 120V line from the boiler control itself. I think that might be an issue for some if they want to DIY this control install, but other than that, the rest of the installation seems pretty straight forward. The customizable settings and status/error code display are great features to have, so I think it was well worth the extra work involved for installing this control.

Thank you to Rey for the directions on how to wire this up. Without that direction I would have been lost. Follow what is written and it will work perfectly. I errored in my first hook up and kept getting a "HARD LOCKOUT". Turns out I put 4 wires together, when it should have been blue to blue. Once separated, it ran perfectly. Took me longer than 20 minutes, but if I had not combined those four wires, it would have easily been done in 20 minutes. Thank you again Rey! Great directions, sure better than the booklet with the unit. :-)

The directions were not clear on how to wire the controller. They do not say that when wiring the controller the limit and the hot line needs to be energized in order for it to work.

Works awesome, easy to install, thanks.

This controller works as expected and its nice to have the readout for diagnosis but I think Honeywell fell short with their installation instructions. I'm not a dummy when it comes to installing things like this yet I was scratching my head with this one. Finally figured it out after a call to my dad (retired plumbing and heating contractor) for some advice.
