i have a pf100 Harman pellet stove. Feed adj at 4, normal setting in automatic mode. I put my wall mount temp set to 60 and even at the inside temp at 70 it continues to run causing pellets to burn through quickly.
Harman PF100 Pellet furnace won't stop cycling

Try a manual reset by shutting the breaker off for a bit. Any blink codes currently? page 22 of the manual: http://downloads.hearthnhome.com/installManuals/PF100.pdf
When was the last time the ESP (exhaust sensing probe) was cleaned? page 33 for location
The other thing to check would be the wall mount connections to make sure they are secure and in place. Apparently there is a thermistor in the wall control that may be getting an improper read. Switching it to service mode should tell you if there is a problem with the wall mount readings. If the problem continues, it is within the furnace itself.
Make sure power to the unit is off (breaker) before working on it!
