Video {- demostration "How self-tests works":-} To check EEV connection, you can use a stepper motor. If you are testing a real EEV, it will be closed after the first "beep" and partially opened after the second "beep". If it's not, check if stepper or EEV center pin(s) connected to +12V and try to swap coil-end pins (EEV1..EEV4). {-EEV photo here-}

Here are no instructions for choosing the right placement for permanent installation of the controller. It depends. You're building your system, and you know much better "where" and "how".<br> Here are no instructions for choosing the right placement for permanent installation of the controller. It depends.
