primary control for residential oil fired burners used in boilers, forced air furnaces and water heaters.Applicable for use with both

hydronic and forced air systems.

- Used with a cad cell flame sensor, operates an oil burner and optional oil valve.

Universal Oil Primary Part Number:

R7284U1004

• Error history for “deep dive” troubleshooting

Last 10 errors What the error was How many cycles ago it occurred

• Diagnostic information can be hidden from homeowner view

• No external tool required!

Points the technician towards the cause of failure

i


R7284 Features - Diagnostics with actionable information

• For the Oil Dealer- Reduce unnecessary part changing

- Reduce service contract costs

- Reduce customer costs

- Reduce call-backs

• For the technicians- No more head scratching in front of the

homeowner

- Show the homeowner why you’re changing the right part

- If lockout was due to voltage – show the homeowner why you’re not changing anything!

Improve Customer Service and the Bottom Line

R7284U Features

• Universal compatibility- This control replaces Beckett, Carlin, White Rodgers

and most prior Honeywell Residential Oil Primary Controls

- Can be used as an interrupted or an intermittent control- One OS# covers the full range of timing offerings- One control covers 15, 30, 45 second lockout

timings

• Field Adjustable valve-on delay, trial for ignition (lockout times), and blower-off delay- Valve-on delay 0 to 30 seconds in 5 second increments

- Trial for ignition selectable 15, 30 or 45 seconds

- Blower-off delay 0 to 8 minutes in 15 second increments

• Pump priming cycle

• Limited recycle
