BMPlus3000 works intermittently

Post by Doldrums » Mon Feb 05, 2018 12:03 pm

Specs:
  • BMPlus3000 rev B
  • Conventional / Gas / Single Stage
  • Using Zone 1 with 2 dampers. Zone 2 with 1 damper.
  • 2 Stats - Both Sensi units. Configured for Gas 1 Stage as well.
Problem:
This unit works perfectly 90% of the time. Other times, the HVAC will not click on for heat.
The LEDs show properly (LED 6 - Zone 1 & LED 7 -Zone 2 are both lit; as well as LED 10 - W1 being lit).

It will sit in this state for hours until I either: a) hit the reset button (which works sometime) or b) kill the whole units power and then turn back on.

If needed, I can chart the run-times for you (in case you think I'm hitting some sort of timer limits).

Any help is GREATLY appreciated!

Thanks,

Hugh (Doldrums)

SOLVED: I have determined the board is working properly, as I used a meter to test System outputs. The furnace board is being flaky.
