Zwave wrong endpoint configurations

I think i have screwed up my endpoints at some point in my zwave adventure
I mainly have heatit thermostats (trm3)
& heatit dimmers.
Have a look at the attached snapshot of the settings. How should this look?
On one thermostat:

Node 34 do not exist anymore, what is the best setting here (i want only direct to controller)

On dimmer

I can see i can choose endpoint 0 or 1 on the controller (UZB) what is the difference.
