Help I have 3 w wires w1 w2 w3 and humidifier. 
I have w1 plugged in and w2&w3 wired together into w2/aux and humidifier plugged into * spot. 

I don’t have gas only electric I have a heat pump system. 
The heat pump is plugged into ob. 

Will this work ok? It’s telling me It’s dual heat source, but I don’t have 2 heat sources? Just electric?

I had to have someone come out and wire it, they said I didn’t need the 3 stage and changed the wiring. Hopefully that doesn’t cause any issues. It does seem to be working now thankfully.

With multi-stage heat like you have, the 2nd and 3rd heat sources are what makes it a Dual Fuel system, It doesn't matter if it is all-electric.

Try this

Black - W3 to * (set to W3)

Brown - W2 to W2/AUX ( set as AUX heat)

White - W1 to W1

Green - G to G

Yellow Y1 to Y1

Blue - O to OB

Red - RC tp Rc (jumper to RH and AUX1 not needed)

Red - AUX1 - not used

White - AUX1 - not used
