First off it is a basic basic honeywell digital non-programmable thermostat. It has the two switches at the bottom to select auto/on and cool/off/heat and the screen is a single display with only two arrow shaped buttons to change temp setting. Deminsions are approximately 3" X 3". Very baxic.
Here is my question, how do I change it from Celius back to farenheit? It seems my mother-in-law() saw fit to mess with it and now it reads Celcius.
Look inside it by the batteries or on the back for a model # and google it ie: RTH 2100 owners manual and you may find one on the net. Usually you have to switch it to OFF and press and hold both those buttons at the same time. Then a menu comes up and you use the up/down arrows to scroll thru it and find an item to change. I WOULD NOT attempt that w/o the manual as you could change another setting and make it worse.
