It doesn't have to be turned off for a few hours, just turned off and
back on. Record what it does when power comes back on without a call for
heat. If it shows normal, stays that way for a few mins, then turn
up the thermostat and see what happens.

I turned off the power.
Put the covers back on.
Turned the power back on.
Waited about 20 minutes.
Turned it off for a few minutes.
Turned it back on.
Set the heat to HOLD at 80 degrees.
The blinking lights don't seem to have changed.

Here is the latest blinking light - which is odd as it stumbles
at 24 seconds, but I don't know what to make of that anomaly.
