Circuit Board (part# compatibility with other GQ59 units)

  • Dipswitch settings
  • Programmed vs Power Supply and location of fuses.
  • Wire harness and unique one-of-a-kind connections
    • Except the green freeze protection and yellow power supply

Dipswitches are located on the green side of the circuit board. Adjustments to these settings effect the fan motor operation characteristics for elevation and vent length/diameter, and configuration.

The circuit board connections are numbered for reference and sized to match with only one other connection on the wire harness. Some units will not use all locations on the circuit board because the same circuit boards are used for other model units.

Freeze protection heaters are identifiable by their green clip connections. Technically, only these connections can be connected to one another and potentially mixed and matched and that is okay. If one gets powered up, they all do. But if you cared to get it exactly right. A thick marker is used to verify all connections as part of the quality inspection phase.
