Wiring in thermostat without circuit board, C wire help

[Overwatchst6]

@speadie i will check the white wire tomorrow. If there is grooves i will let you know, If not I will use it as the C wire.

Thank you so much!

@speadie so there is no other heat control in the house, and when i turn the heat on, the fan blows but no hot air comes out.

Are you able to tell which nut the W wire should go into, and which ones i need to hook up my c wire adapter to?

I really appreciate your help, thank you so much!

Can you clean off this label and take a clear picture of it?

[Overwatchst6]

Yes, I will do that tomorrow and send a pic. Thank you

@speadie here is the picture of that label. I also included a closer picture of the heat kit label. Thank you so much!

This blue wirennut with the white wire is W

to connect the C adapter and use the wyze thermostat with heat strips and cooling, the wires should be connected as follows:

tell the wyze that your old thermostat has the following wires:

Rc, G, Y, W

@speadie Thank you so much, I’m going to try this. Just two quick questions, the top and bottom pictures have the Y and G wirenuts labeled opposite, im guessing the bottom picture is correct?

Also the C wire adapter i bought was Honeywell with R, W, K, C will that work, and if yes, is this the proper letter conversion?

Honeywell = Wyze

R = R

W = W

K = Y

C = G

Not sure on the C wire adapter from honeywell, the wyze comes with its own C adapter.

as for the wirenuts, the one with the thin green thermostat wire and thick white furnace wire in it is G.

the one with the thin blue thermostat wire and thin white A/C wire in it is Y.

in the top picture, it’s hard to tell which wire is in which wirenut, which is why I also labeled the wirenuts in the bottom picture
