DAMPER CONTROL BOARD CALL OUT AND CONFIGURATION
DAMPER CONTROL BOARD ADDRESSING / CONFIGURATION
Each damper control board must have a unique address from 1-10. To set the damper control board address there is a
jumper on the board. Find the first damper in the daisy chain and place the jumper on ZN1 for address #1. Go to the
second damper in the daisy chain and place the jumper on ZN2 for address #2. Continue addressing the damper control
boards in numerical order of the daisy chain wiring.

Setting Damper Boards for Heat Pump Operation
When the GEN II-R controller is set up for Heat Pump operation, every damper board in the system needs to be
placed in heat pump mode. This allows the dampers boards to work with heat pump thermostats. Place the HP
jumper on both pins.
