I have a 2011 Harmon XXV-TC pellet stove with the touch screen control, I have done regular maintenance 3 years I will shut the stove down before I go to bed at night mainly because it is not too cold overnight this time of year and when I get up in the morning my house temp is 63 the stove temp on the touch screen says 85 and I know that can't be right, I have the little controller deal on the wall approx 15 ft away that tell the stove when to turn on and off and it is set on the touch screen to come on when the house is 72 but when winter gets here I will at times want to have the stove come on at about 69-70 at night and if the touch control stays at 85 the house will get cold but the stove will not respond until its 85? what am I missing here it has been running great the last 3 years this is the only glitch has had.
