Dometic Thermostat : Furnace offline?

Anyone know why my furnace all of a sudden failed to display on a 2018 Montana 3730? It is like the furnace is not there at all! A/C and Fan modes only on display. Worked good last night - all of a sudden - no furnace? Error code 1 displayed for an instant - now nothing. Rig is on a surge protector and all circuit breakers are good. Ideas?

I have no idea what happened but on a whim I pressed the Mode button simultaneously with the Down arrow for 2-3 seconds and the furnace display came back online. It briefly displayed Cod1 then the display was back to normal and appears to be working. FYI Incase someone else has this issue.

I had just finished my second beer - the rest is history.
Thanks,
