Thermostat wiring - Eco-Cool 15k
Hi all. Brand new to the forum. I'm trying to replace my Dometic 13k ac with a Gree Eco-Cool 15k unit. I'm confused about the thermostat wiring and it's connection to the AC unit.
The thermostat has 6 wires - Red, Black, Yellow, White, Blue and Green.
However, the existing thermostat wiring that runs through the walls up to the AC unit has Red, Black, Yellow, White, Orange and Brown.
Only 4 wires connect. I've ruled out Yellow and White as neither was connected to the old unit.
My issue is that one end I have R, B, Blue and G and on the other end I have R, B, Brown and Orange.
The thermostat has power but is pulling a "04" communication error.
I'm at a loss. Any help would be appreciated. Thank you!
