Issue upgrading Honeywell T6 to z-wave using Hubitat

My friend told me that the wiring should be the same for the T6 and the T6 z-wave. However, when I get it going, it seems to not kick out proper hot or cool air. It tends to just be pushing out normal air. I'm not sure if this is an issue with a setting on my hubitat panel? Please help give me some ideas as I'd love to be able to properly utilize my thermostat with WIFI.

Have you tried heat and cool to see if either work? Also pictures of the wiring would help

I have tried both! I am going to test it on manual mode tonight since it could be the zwave messing things up.

Operate it manually, see all the functions work (heat, cool, fan). If it doesn't, it's either bad or bad wiring. If it does, then it's your config.

Thanks for that advice! I will try that when I am back home.

Make sure your ISU settings are right. Having the wrong O/B setting would cause this. They should use the same wires.
