Gary R.: 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.

Robert Beamish: 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.

Kindle Customer: Limit= 120v input from via the aquastat or what ever your furnace is sending to command the heat on
L1 = hot wire for constant power to the primary or you can wire the limit wire to both limit and L1 but the primary will only turn on when the thermostat commands the heat on
L2 = neutral
Burner motor = output wire to the burner motor the white wire for the motor will connect to the other L2
Igniter = Output wire to the igniter my wire was blue the igniter white wire will connect to L2
Cad cell = input from cad cell ..... info about the cad cell when everything is wired shine a light on the cad cell and the primary should read 1600 ohms Or less with no light source the primary will read 9999999 if the furnace is running and the primary reads 9999999 The cad cell is bad or your wiring from the cad cell is bad this will cause a hard lockout
Settings I used
Language eng
Valve on delay 000 I have no valve
Ignition time = 0:30
Burner off delay 0:00
TT configured on = Yes..... the reason I did this is because my thermostat does not connect to the primary and i didn’t want to jump the front TT connections if you...

Randy CarpenterRandy Carpenter: I have a 140MBTU Burnham Boiler that the failed during a snow storm of course. No parts where available, so I ordered from Amazon. The parts arrived within 5 days due to weather. I have a Honeywell 3 wire primary oil burner controller, and found the directions quite lacking having installed many oil burners throughout my years as a general contractor. I read the reviews, and I appreciated some of the very detailed comments, which did shed light on the installation instructions (or lack thereof). I have included some diagrams and photos of my boiler to assist those of you who may not understand what others have described, as this really is not that difficult to do. I have also listed some other things to consider while you are reading this getting ready to order.
You should have a 3/8 combination wrench (Oil bleeder). 7/16 combo wrench (Oil pump supply tube), 5/8" combo wrench (Nozzle & Oil Filter Housing), Pliers (Slip joint or waterpump), Needle Nose to pull wires, A flat heat and Philips screwdriver, A small cleaning brush, wire strippers, crimpers, electrical tape, AC Volt Meter or DMM, some foil pans & rags, cleaner degreaser, a flashlight, and a few braincells...

Ross Hawthorne: 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. :-)

JoeJoe: 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.

The Gardener: This control requires connections to be made with push- on 1/4 male connectors. Comes with pigtails and wire nuts but you might want to just add the right connectors directly to you existing wire leads.
