Detection of jumper configuration

The wall modules T7460 have a jumper for W7753/ XL500  controller selection. This jumper setting adds a 10K resistor in the fan switch/ bypass circuit in the XL500 position.

The position of this jumper is not relevant for the operation of the module, because its position is automatically detected and program control is changed accordingly. When the position of this jumper is changed during run time, it may be recognized as if the bypass button is pressed.


The wall module T7560 does not have this jumper.
