Utica 3 pass 86+% oil boiler W/field controls oil vent damper combined with a Harman PB 105
Plumbed series so I can bring all 200,000+ btu's online...all controlled by existing oil burner controls, and an intellidyne hw+ model 3250.
Last night...-16° heating 2 buildings P B 105...full tilt ...oil burner ran .2 or 12 minutes
 (intellidyne hw+ model 3250)  I suspect the oil was necessary to bring zones back up from DEEP setback (my setback temp ..50°)    .178 gallons oil!...  and 6 bags pellets....warm corners...priceless
