I am a big fan of the intelligent conversations on this forum. I gave gained alot of knoweldge.. I hope that you guys have some wisdom to impart.
I have a TARM excel 2000 with 620 gal STSS storage tank with pressurized loops. While burning a load of wood with the boiler at operating temp, I would hear a "chatter" in one of the control boxes which sounded like a relay cycling quickly. The fan would then quit. I would shut off the boiler and turn it back on and the fan would start and operation would continue. This was an intermittent problem.
Now, I find the fan still running long after the load of wood is gone. I have adjusted the stack temperature monitor but it has no effect. I have the boiler plumbed according to the TARM recommendations. I have shut off the boiler but this closes the zone valve to the storage tank so my reserve haet is inaccessible.
Is my sensor in the stack bad or is a relay shot? Any ideas? Thanks for your help
