my therm died, on a hot spring. i want to change from a 1-8 therm to a digital therm with a set back run with x10 any ideas. e mail me at joecanyonlake @yahoo.com

If you mean changing from original controls to digital, not going to happen. If you have a 1994, you can change from mechanical t_stat to electronic T-stat and thermistor, but it will still be 1-9 and appear virtually identical.
