    Does anyone have a list of codes for the older bunk model? I just replaced mine and it won't ignite. Same problem as other heater. Both are older models.

    How do I set the #### thing to shut off on its own? Only thing that I have that controls the unit is the temperature knob in the sleeper. However even when set at less than a half point it stays on until I manually shut it off. Also the fan is working the whole time so after a few hours it tends to drain my batteries. It was in the truck when I bought it so I have no idea if this how it normally operates or is it faulty.

    if it is warm in sleeper air heater shuts off, but air heater blower keeps running at low speed, and when temperature goes down it restarts.

    Yepm it drain batteries.

    If it is draining your batteries then you need to have your batteries tested. I can run mine for a week and still start my truck .

    the good thing is opti idle, icon and other stuff that starts engine with low batteries. But usually no this systems are installed and battery protection systems wake drivers up to start!

    granted mine was an Espar.

    Likely a dealer only item.
