Custom Zwave Thermostat Device Handler

Hello

I have a generic Zwave thermostat and I can’t seem to control it properly.

Can anyone help me setup a perfect device handler for it?

I’ve added this screenshot to show you all the different modes it may have? I’m a complete noob if someone could just set me up in the right direction it would really help.

For Starters, I’d like to just be able to turn on and off the thermostat accurately.
