Temperature varies 13 degrees around setpoint on...

Thanks for your thoughts, I really appreciate it. No, not using a remote thermostat, just the built in digital one.

A GE tech is scheduled to come again tomorrow. Hopefully this will be a more experienced person than the one that came last December, and who can help,

The unit was new just 2 years ago (Dec 2005) and replaced an 8 year old zoneline that worked flawless for 8 years.

When the current unit was originally installed the outside temperature was mild and the aux (electric elements) did not turn on. Before the weather got cold enough to use aux heat we left for Florida for the winter. It wasn't until last December (2006) that the weather was cold enough to require the aux heat. That's when we first were aware of the 12 to 13 degree variation in room temp.

A GE technician came about this time (Dec 2006) last year and replaced a few parts. (He was frustrated and not familiar with the zoneline and cut wires and spliced components etc) He was a butcher and used a shotgun approach to troubleshooting. However, the weather was again too mild to require the aux heat, so we had no way of knowing if it was fixed or not. We again went to Florida for the winter, and did not know till last week that the problem still was not fixed.

Hopefully GE has kept a record of my complaints and will still fix the unit in warranty, since I reported the problem before the 1 year warranty expired, and it has not been fixed.

Sorry to get so wordy, if that's a word, but that's how this stand.

Thanks again for the help. I'll you know if this thing gets fixed.

Kind Regards,
Ron in Cincinnati
