Here is the programming manual for that thermostat

Thanks for letting me work with you. When we are finished,if my answer has been polite, professional, and thorough,please locate the 'rate your expert button' and click one of the ratings .If you still need help let me know!.
Rating will not increase your charges, nor close the question, but is how I earn my living.
I am here, but I must come and go to handle the wide range of questions I get and to do research and type up the answers,
If the arrows used to move the temperature up and down but no longer do, try this:
1. remove the batteries and refit them but *backwards. Leave the thermostat that way for 5 minutes, then put the batteries back in the correct order, make sure they are new batteries,
2, then try it again.
If that fails, reprogram the thermostat from scratch starting with step number 1
Let me know how that goes, if that fails its time to buy a new thermostat,
You will probably need help getting the right one that is easy to wire and program, I can help you with that when the time comes,
You are welcome
