PRO-AIR / FIREFLY REMEDY INSTRUCTIONS – RELEASE 2
Temperature Sensor Procedure:
•
•
Remove ProAir intake filter and cover. Inspect wiring for loose connections. Determine if the temperature
sensor is located in the intake or somewhere else.
If the temperature sensor IS located in the ProAir intake, follow the procedure below.
If not, Skip.
o Disconnect and remove temperature probe
Be sure to tape any holes left in the shroud by the sensor
o Trace the wire in the intake to determine if it enters the opening from the Road side or Curb side.
o Remove top panels (fastened with screws) from the bottom of the overhead cabinet adjacent to the
temperature sensor wire point of entry.
o Remove the temperature sensor wire from the ProAir air conditioner cut out and route into the bottom
of the overhead cabinet.

•
If the temperature sensor is NOT in the ProAir intake, follow the procedure below.
o Galleria
Remove Galleria switch board to gain access to Firefly G8 board and temperature sensor wire.
Using a wire/cable pulling tool, fish the 16ga red and 16ga white wire along the top of the
overhead cabinets from the Firefly G8 board to the new overhead cabinet temperature sensor
location.
It may be possible to route these wires through overhead cabinet bottom shelves by drilling
through cross members on some floorplans.
On the Galleria 24A Floorplan, it may be necessary to pull the refrigerator to accomplish wire
routing.
Connect 16ga red wire to 12V+ temperature sensor lead
Connect 16ga white wire to 12V- temperature sensor lead.
Mount the sensor on the bottom of the overhead cabinet.
Connect the 16ga red wire to Pin 1 on J3 of Firefly G8 board. See “G8 Form”
Connect the 16ga white wire to Pin 7 on J3 of Firefly G8 board. See “G8 Form”
Power on Firefly system and verify temperature is reading properly. If it is not, reverse red and
white wires.
Reinstall Galleria switch board
Overlay felt material in overhead if needed. Felt material length may need to be cut down to
size for some floorplans.

Either by hand or using a wire/cable pulling tool, fish the 16ga red and 16ga white wires from
the bottom shelf of the overhead, along the top of the overhead cabinets, to the Firefly touch
screen opening.
Connect 16ga red wire to 12V+ temperature sensor lead
Connect 16ga white wire to 12V- temperature sensor lead.
Mount the sensor on the bottom of the overhead cabinet.
Connect the 16ga red wire to Pin 1 on J3 of Firefly G8 board. See “G8 Form”
Connect the 16ga white wire to Pin 7 on J3 of Firefly G8 board. See “G8 Form”
Power on Firefly system and verify temperature is reading properly. If it is not, reverse red and
white wires.

Charging verification and venting procedure
•
The following test should be performed on both shore power and generator power:
o Start the ProAir air conditioner on Auto with the set point at least 5 degrees lower than the displayed
room temperature.
o Using an clamp meter, verify charging amperage meets or exceeds ProAir amp draw
Measure ProAir amp draw on 2 gauge cable from “Load” post of the BG160.
Standard coaches with generators have 2 chargers. Xantrex XC-2080 and WFCO WF-9855. The
combined charging amps of both chargers should meet or exceed ProAir amp draw.
Li3 Coaches (no generator) have 1 charger. Xantrex SW-3012
o Add venting to the top of the charger compartment, across from any existing venting.
o Drill (at least 5) 2” holes, install vent to cover vent holes.
o Some components may need to be relocated for vent installation

Firefly programming and wiring procedure
•
•
•
•
Firefly multiplex system should be updated to either v4.20 or v4.23. Version can be determined at the bottom of
the settings tab on the touch screen.
At the G8 Board, inspect/ensure positive connections at J8 pin 3 & pin 4 and J9 pin 7 & pin 10.
J9 pin 10 uses a resistor harness. There are two legs that branch out of the connector. Ensure the longer of the
two legs is securely grounded to a ground bar and NOT Solar panel negative.
Verify cooling occurs in manual mode at ~30% and ~ 100%. If the A/C cools at 100% but not 30%, Compressor
High and Compressor low are reversed (J8 pin3 & pin 4).
