KLeask posted for all of us...

A couple days ago, I noticed my furnace was continuously running - both
the fan and heat. I changed the batteries in the thermostat, to no
effect and am presently manually operating hte furnace by tripping the
breaker. The thermostat (honeywell programmable) was installed last
December.

Any ideas?

Thank you,
Karen
