Thermostat Automation not working


I bought a qubino z-wave thermostat to be able to remotely contol the temperature using HA and of course to setup some basics like day- and night-temperature.

Unfortunately, the following setup doesn’t work:

The only way to currently set the temperature is using the thermostat-widget while this results in a nearly all-time runnning heater. (No option to set cold_tolerance and so on)

Any idea how to get that to work?
