Honeywell ERV ER200B

I am using American Aldes ZRT registers which will permit a constant low flow ventilation in my bathrooms until a timer is activated. At that point a damper on the ZRT opens, a microswitch engages to trigger the Honeywell ERV to high speed mode. The ERV schematic shows +12 Red being switched to the Black dehumidifier line to trigger the ERV to high speed to high speed. When I open the trigger line jumper, the ERV continues to run on high speed. What is not covered in the technical documentation is if an internal ERV timer is activated.

I've contacted the manufacturers & await their response. I am wondering if anyone on the forum knows?
