    Hello

    When you select off, the convection blower shuts down when the ESP goes below 165 Deg F and the combustion blower shuts down when the ESP goes below 92 deg F.

    A complete stove shut down on auto must depend upon some thermister info from the room probe?

    I just bought a brand new dip switch board to have the latest revision and the new black room probe. The ramping down of the fire seems to work better now with these two!

    The room probe is a switch. When the temp reaches your setting it does the same as turning the stove to off for what I know.

    I really do not think there is a switch at the end of the room probe like a T-Stat. Also if you do put a real T-stat with a switch in one leg of the room probe, you get the 3 blink status light error when the T-Stat switch is open.

    I just turned the Temp dial from 80 to a notch under 75. The room wall Thermometer read 80 and the stove shutdown! Then I opened the garage door and the stove started to fire up!

    Does 6 degrees difference between the room temp and the dial setting trigger a shutdown?
    There must be some criteria here?

    Not a switch such as a wall switch. It tells the computer when to start shut down when the room temp is reached and the esp does the rest.
