Question About Honeywell Thermostat 1F90-51
Digital comfort sett ll...

I would like to use this w/out programming it as it will not reset itself to be reprogramed. I changed batteries, left them out o/night but when batteries put in it immediately goes to programming mode. Its 20 yrs old and I would like to use it or change it out. Best advice?
