Hi,
I need some help connecting my Lux TX1500 to my Bryant coil (furnace/AC).

Bryant model number: FB4BNF024

It has a Totaline thermostat (trying to replace) with the following coded/colored wires:

W - White
O - Orange
G - Green
R - Red
C - Blue
Y - Yellow

The Lux thermostat has the following connections:
G
Y

Can anyone help?

Thanks,
Dave
