I turned up the thermostat for it to start up and now it flashes “return” and don’t know why.
What can I do?

I am 75 and had many thermostats and Honeywell Thermostat RTH221B 1021/A 1 Week Programmable must be the most frustrating unit I have ever had.. Retired you don’t need all the time and temperature changes. I have had Many thermostats from Honeywell and this is the first one I detest. My previous Honeywell was simple and worked for many years and was programable as the previous one’s did with no frustrations.
I leave Saturday for vacation and will be back the 22nd.
