Having issues with HFS-6

[Richard L]

open up the FCM...

1. Pick out the brown wire from the 8-core cable
2. Cut it as closely as possible from the circuit board.
3. Cut the "non-red" wire off the solenoid valve pin. Tape it up.
4. Solder the brown wire to the same pin.
5. Now the valve is driven directly from the controller.
