If you tip the mercury switch so that it makes contact and the furnace
doesn't start, it isn't the t-stat. Check the connections, then
start checking the furnace.
In any case, ditch the mercury t-stat (recycle it properly) and get a new programmable one if at all posible. It will pay for itself many times over by turning your heat down in the middle of the night and back up by morning.

You need to get into the installer setup. Download the installer manual from Honeywell or an on-line vendor and it has the installer codes to alter the maximum heat setting. Press the system button and then buttons 2 & 4 at the same time for 5 sec to enter the installer mode. I believe the code is 0600 and then you enter the max temp for heat setting. Press done and your done!. Try this link for the installers manual http://www.alpinehomeair.com/related/Honeywell_VisionPro_8000_%20Install_%20Instructions.pdf

press run program.... from there, set the schedule for maximum efficiency. permanent hold only shows up after the hold button has been pressed 2-3 times. If this does not fix the issue, there is a master reset button on the thermostat that will set all settings back to factory default.

I just had this happen to me a few days ago. I hope you find this response before you did what I did and paid an AC guy $103 for him to do about 5 minutes worth of work. Here goes.
The power is shutting off because your drip line is clogged. Your drip line is the tubing that goes from your compressor (inside) to the outside of your house. When that tube gets clogged up (with algae and dirt) then the water will backup in the line. There is a protection circuit in the line and when it detects water (because of a backup) then it shuts all power to the AC off. If you take a shop vac outside and **** all the **** out then you'll be fine. The AC guy said that when I replace my filter every month that I need to pour about 1/2 cup of bleach in the line (from the inside) to prevent algae from forming and stopping the pipe up. Hope this helps someone out there before it costs them a $100.
