Customer Question
Just installed a lyrict5...

Just installed a lyrict5 thermostat, but no screen appears

Contractor's Assistant: Just to clarify, do you think this is a larger HVAC problem, or something specific to the thermostat?

I suspect its wiring related or thermostat related. Furnace works fine previously.

Contractor's Assistant: Do you plan on doing the work yourself?

I just removed a nest, and installed the Honeywell myself.

Contractor's Assistant: Anything else we should know to help you best?

Furnace works fine when I jumper it and force it to run. Furnace ran erratically with the Nest. Nest setpt temp changed randomly while no program setting were in entered.
