If your Bryant Thermostat displays an E1 error, it means the Display Module and the Equipment Control Module cannot communicate via the two-wire connection.
How to fix a Bryant Preferredt display module that doesn’t power up?
If the Bryant Thermostat's display module doesn’t power up, check the Rc/Rh and C terminals for 24VAC. Also, check the voltage between Vg and V+. Ensure the polarity is correct during wiring, as the display won't power up if reversed.
Why does my Bryant Preferredt Thermostat show dashes for Option 01?
If dashes appear for Option 01 on your Bryant Thermostat, it's likely due to the red pigtail being wired to Rc or Rh and the black pigtail being wired to C. To resolve this, remove the two-wire pigtail and connect it to the V+ and Vg terminals.
