Premium Efficiency Control Board Configuration Notes
• J6 is the CANbus termination jumpers. If the condenser is the last device in the CANbus
communication line, the jumper must be placed between Pins 1 and 2 of J6. If the condenser is
not the last device in the CANbus communication line, then the jumper on J6 must be placed
on Pins2 and 3. CANbus communication errors may occur if the jumpers are not in the correct
positions.
• A jumper must be present at J2. If a jumper is not present, the control board will not boot
properly during power startup.
