5-2 Day Programmable Honeywell Thermostat Upgrade

Did the Honeywell mod a while back. The only issues have been when the TT was in storage at extreme temps (below 50f or above 110f). The thermostat would read EE as it did not recognize the extreme temp. I had to manually jump the terminals to get heat/ac to run. Once within the range, it worked great at keeping the temp +/- 1 degree.
