Still having the same faults ... generally when high demand (high fan speed) is needed. Also, I have observed that
the problem goes away (or is at least infrequent enough that I haven't yet seen a failure) if I set DIP switch #6 to
"ON" indicating an "Outside" installation location. Does anyone know how this setting changes the control/safety
functions of the unit ? While I appreciate the improved operation, I am a little concerned about the safety implications
(the unit is installed in my garage -- presumably "Inside" ... but doesn't have a direct vent -- combustion air is pulled from
inside the garage itself).
Again, any ideas suggestions or information appreciated.
