I also bought an electronic ignition coil and an oil cutoff valve and a new electrode set and filter to go with it. I really like it having the ability to run the Beckett burner motor before turning on the oil and then turning off the oil before shutting the motor off because of the much cleaner start and stop as far as the nozzle is concerned. Also I use the interrupted spark mode which is so much easier on the electrodes. The ability to read the ignition time history and the CAD cell resistance real time helped my find a problem with my nozzle holder as well. I am relying on the latter two readings to tell me when to change the nozzle and electrodes now after removing it after the first winter and seeing how clean they were. Review: GREAT CONTROLLER, GREAT VALUE FOR THE COST! - I have a 140MBTU Burnham Boiler that the failed during a snow storm of course. No parts where available, so I ordered from desertcart. 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 that still function would be helpful. Along with the tools, there are parts you really should consider. Doing a full servicing while you are down, if you haven't already is not only smart, it's a lot easier since you are taking the motor apart already. 1 Order a new igniter, as this will only help if you are already having issues, its 2 wires and 4 screws, that's it, the Beckett unit was $59 on desertcart with 3 day delivery and it included a CAD cell complete with the gaskets 2 Make sure you replace the COMPLETE cad cell and wiring harness, as it is cheap insurance if your not planning on doing the igniter, or if it is new. Make sure you clean the igniter springs thoroughly 3 Replace your oil nozzle, the Delvans have it stamped right on the nozzle (80A 1.25) etc, or look on the boiler 4 Replace your oil filter, the gaskets on it, and clean or replace the oil pump screen & gasket 5 Order 25 pack of Blue T&B butt connectors to use the factory supplied color coded jumpers with insulated connectors already on them supplied with the new controller 6 Order 25' of 14ga Stranded Red and Black primary wire, you will use this for the installation 7 Pick up some degreaser/ cleaner, a small brush to clean with, and some Odor control spray for the fuel oil 8 Pick up some small foil pans at the grocery store to catch oil under the parts you are servicing. 9 WHILE YOUR AT IT, BUY A BOTTLE OF ALCHOHOL, IT ALWAYS HELPS. 10 Read the programming notes on the diagram, these are for a Boiler, not a furnace, if you have a furnace set the Type: FURN, and you can change the Ignition time to up to 45 seconds. A BOILER SHOULD BE MAX 15 LAST BUT NOT LEAST: MAKE SURE YOU TURN OFF THE ELECTRIC AT THE PANEL! Turn the thermostat to "Off". When you do the initial power up, you can go into programming without the thermostat calling for heat. turn off the service switch at the boiler for safety, then shut off the oil line at the tank to prevent leaks while servicing. ## Features - 16 character two line tri-lingual display provides simple programming and diagnostics on select models - Enunciation of status and faults via LED or display - No additional tool to purchase to take advantage of all control features - Model number: R7284U-1004 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0058UHG5Y | | Best Sellers Rank | #260,424 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #105 in HVAC Controls | | Brand | Honeywell | | Brand Name | Honeywell | | Color | Color | | Customer Reviews | 4.6 out of 5 stars 444 Reviews | | Display Type | LCD | | Global Trade Identification Number | 00085267344708 | | Included Components | Honeywell R7284U-1004 Universal Electronic Oil Primary with Programmable Parameters and LCD Display | | Item Type Name | Electronic Oil Primary | | Item Weight | 1.5 Pounds | | Manufacturer | Honeywell | | Model | R7284U-1004 | | Part Number | R7284U1004 | | Smart Home Compatibility | Not Smart Home Compatible | | UPC | 085267344708 094714274482 | | Unit Count | 1.0 Count | | Warranty Description | No Warranty | ## Product Details - **Brand:** Honeywell - **Style:** electronic - **Power Source:** Corded Electric - **Color:** Color - **Item Weight:** 1.5 Pounds - **Global Trade Identification Number:** 00085267344708 - **Number of Items:** 1 - **Manufacturer:** Honeywell - **UPC:** 085267344708 094714274482 ## Images ![Honeywell R7284U-1004 Universal Electronic Oil Primary with Programmable Parameters and LCD Display - Image 1](https://m.media-amazon.com/images/I/6174EkMLxCL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ 4+ years and works great so far *by C***R on June 12, 2026* I bought this to replace the original old school controller in my 90s Intertherm oil furnace.
