Understanding Honeywell Electronic oil primary R7284B

Can someone clarify for me what this digital replacement controll will do? Will it replace the 24v tstat circuit and fan relay assembly (may not be using the right terminology...sorry) on this older Unicell oil fired hot air furnace? Looked at the instructions a few times (horrible btw) and was hoping to find a bit more info on line about actual installation. Striking out. -Dan

    What problem are you having? If you just want the control to work you are going to have to run another wire from the service switch to the control.
    To provide a wiring diagram we would need to know what other components are on your system. Fan limit switch? Fan center?
