The thermostat probe for the castle serenity ps is located attached to the back of the stove enclosed by a metal bracket. Because of its location, it is not very accurate. (to close to the hot stove and exhaust piping heat) . I have to set my stove thermostat 8 or 9 degrees higher to make it heat to approximately 70 degrees in my adjacent kitchen because of this. While recently working on my ps, I noticed the probe wire has several wraps inside the stove wrapped around other wires. After cutting the plastic tie holding the wires together, I found that the probe wire has plenty of slack to extend the probe almost three feet away from the rear of the stove and to the side. It appears they included this extra probe wire length for that purpose, but I have not been able find anything about it in the manual. With the probes new location away from the stove, I can now set the thermostat to 70 on the stove and my adjacent kitchen 20 feet away stays at 70 degrees. I also noticed that the stove seems to cycle differently and more for the better. May even end up saving some pellets because of this fix. Seems to spend less time on high #5 and more on low and keeps the temperature pretty even throughout the house, too. Anyway, the stove seems to act better with the new location away from the stove. Maybe it's just my stove with the extra probe wire length. If you want to check your probe wiring, remove the right side panel (as you face the stove) and follow the probe wire back from the probe.
