Hi everyone,
I've got an issue I would love to square away this weekend if I can. First, the setup
Froling 20\30
plumbed per Tarm schematic 2.12 square tank
Wired per Tarm BLT appendix (page 32-33) of plumbing schematic
Becket oil furnace w\ Honeywell l7224a aquastat and r7184a oil primary
If not in "wood only" mode and certain conditions are met, the blt control will supply 24vac to the tt switches on my oil furnace and allow it to start. Here's the thing though, my oil furnace is still firing in wood only mode. The oil furnace will fire when it hits the low limit set point.
I disconnected the wires from the TT switches on the oil furnace to troubleshot the issue, and those pins appear to always have 24vac on them. So obviously the blt controller can't stop the oil furnace from coming on if the oil furnace aquastat is providing 24vac.
So I think this is more of a "configuration" issue than a wiring thing with either my aquastat or primary on the oil furnace. I can set the oil furnace up for "cold start" but I don't know if that is the answer.
Any suggestions? I attached all the documentation I could think of in case it helps. Thank you for your time.
p.s. I couldn't seem to upload the plumbing schematic, so here is the link:
