oil primary control
ok i know you all are gonna say have a real tech go out and check but i am a real tech just real inexpirenced at oil. i just started messing with oil furnaces and doing maintenances and some repairs.
but my neighbor came over saying their heater isnt working. i walked over and checked it out, they turned it on from the t-stat and the blower came on which was normal. but then that was it and my first question is how the hell do you reset the new primary controller? it doesnt have a reset button all it has is an up and down arrows and an "i" button. i figured id ask here first and im gonna talk it over with my field sup tomorrow. i didnt bring my tool bag over or anything so i know many things could be the problem and im gonna dive into it tomorrow after work im just wondering about this new primary control ive never seen
thanks in advanced
(just tryin to learn and help a neighbor out)
If you are talking about the Honwywell R7284 series-
• Soft Lockout: Caused by a temporary internal error
such as low voltage. The control recovers
automatically after the error is no longer detected.
• Hard Lockout: Caused by a failure internal to the
control or by a system fault such as flame out of
sequence. A Hard Lockout will result in a no heat
condition. To reset from Hard Lockout press and hold
the “i” button for 2 seconds.
• Restricted Lockout: Caused by a number of
consecutive hard lockouts on the same heat cycle. To
reset from a Restricted Lockout press and hold the “i”
button for ten seconds.
Here is a link to the Installation Manual -
"I don't know why it be like it is, but it do"
thanks that helps out alot and yeah thats the model. like i said im gonna go over there today after work and fiddle with it. i just wanted to know how to reset the damn thing lol

Second most important rule is to never tell or show the customer how to reset the primary control because they will most always lie to you about how many times they pushed it (and the burner didn't light) before they called you. If you suspect this is the case....... read the first most important thing to know about oil furnaces.
Use the biggest hammer you like, pounding a square peg into a round hole does not equal a proper fit.
Agreed. Most of the time something like the transformer has gone you light it up and it lights with a bang.

Back in the day when the HO said they didn't reset it I would automatically look for excessive oil if possible . Then reset it and stay the hell out of the way . I Remember having to shut them off and let them burn out ,with the inddor blower running of course .
I don't miss oil a bit
I would read the link rchristie420 sent. I always read the manual before I work on new systems and it saves a lot of headaches. My parents have oil and I tell them to call me before they touch anything.
yeah when i went to the house they didnt have the manual fo rit ofr i woulda read it. but all the wiring was a cluster f**k and they told me a "friend who used to do hvac put in the new unit" i just ended up telling them have him come out figure it out

You gotta watch out for the barometric damper. Had them blow across the basement when the HO only pressed the reset once and called for service.
#1 always check for unburnt oil. If there is try and burn it off with a lit piece of paper or something.
