Question About Honeywell Thermostat CT3400
Thermostat Model No / manual...

We were out of town for a few days and when we returned home we found both thermostatss in our house set to HOLD at 60 degrees. I suspect this is some kind of default setting. Since the thermostats were here when we moved in, I do not have a manual. Can someone identify the thermostat? See picture.
