I have had this stove for 14 years. I have always run it in auto with a extended wire for the sensor, 10 ft away from stove. I always use the temp knob to adjust the temperature in the house. Now it won't ignite and if you get it started manually it will shut itself off. If I switch to stove temp it will ignite and warm the room but it was 84 degrees when I got home. Does the temp knob control the temp when in the stove mode? Doesn't really help to turn it down. I don't know what will happen if I just switch it to manaul. In what modes does the feed rate apply to? Manual auto or both. I have a problem trying to understand the manual. Acts like the control is acting up.
