I’m trying to map my old thermostat wiring with the wyze thermostat wiring. It has 7 wires.
Unfortunately, I’m stuck.
My old thermostat has E/W1 – for black wire (only 1 wire), whereas on wyze. it has 2 connections, E and W1 separate.
Here is my wiring on my old thermostat.
I was able to map the following:
R -> Rc
O -> O/B
C -> C
Y1 -> Y/Y1
G -> G
W2 -> W2
Where should the black wire go? E or W1?
