The furnace should only be connected to and operated by one thermostat, not
two.

Are you aware of how the 2 thermostats are wired??

Good foresight on the problem not truly being solved. I had a
feeling, but was hoping for dumb luck. There are two thermostat
controls (Honeywell T8112) in the house. Does it sound like I need a
new blower relay switch?
