That is probably why the fans run all the time, when the feed rate goes up (0-99), the fans should compensate, the higher the feed rate, the higher the fans. If you have only seen it as low as 76, then you may have to raise your Max Feed or lower the thermostat setting until it reaches room temp and start from there. Make sense?
if your setpoint is always higher then the room temp can reach, it will keep feeding until satisfied. So, the feed rate may stay high. My feedrate drops to 0 when no heat is required (temp 70 = Room Setpoint of 70), Soooo, if your setpoint is 75 and the stove can only get it to 72 or 73, the feedrate will continue to rise and the blowers keep increasing to satisfy the temperature.
Therefore, The stove is too small to maintain a nice even temp (Drafty house, windows, no insulation...etc.)
The Thermostat is too far away from the heat source
The Max setting need to be bumped up a few points at a time to get more heat out of the stove without pushing hot coals off the end.
Keep us posted, we will get it working.!!
