Not adjustable. I just start driving. When you hit 19 MPH the grid cycle will stop.

You can unhook the cable that runs from the solenoid to the heaters. The relay will still come on, but there won't be a load on the other end.

 

Mine will do this also.

Stock batteries lasted for 10 years so I didn't worry about it.

Not sure if IAT has anything to do with it but maybe try cleaning it and see if it helps.

 

with all of the above statements.

The IAT sensor is the trigger.... It might be 65 when you go to fire it up, but it probably was a lot cooler during the night... all of that metal is still going to be cold... as soon as the engine fires up, the intake air is cooled by any cold metal it touches.
