There is a Honeywell model RTH2300B1012, which is what I think you're talking about.
The Honeywell website has the owners manual for that model available online at:http://customer.honeywell.com/Honeywell/getliterature.axd?LiteratureID=69-2448ES.pdf

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.

Hold down the system button on the left side of the screen for a few seconds then after the screen changes hold the two buttons to the left and right of the center button on the bottom of the screen then use the left arrows to get to 670 and the right arrows to get to 0 that is how I unlock mine? Good luck!
