IMPORTANT:
If you have both an RC and RH wire present, remove the RED shorting cap inside of GEO
(the YELLOW shorting cap must only be on one pin, not both).
Wiring is complete - you may return “cover” between terminal blocks
.
Wiring for methods: #1 C-wire, #3 Micro-USB, and #4 Battery Power
4.1a Wiring Terminal Reference: Conventional Furnace - gas/oil/electric & air-
conditioning (without LUX Power Bridge)
Referencing your wiring photo & terminal guide below, wire to GEO.
IMPORTANT:
For Heat Pump applications, the YELLOW shorting cap must be across both metal pins
instead of the default of just one. Also, there will NOT be a wire connected to the “W1” terminal.
