Can't set current_heating_setpoint with Tyua _TZE204_rtrmfadk TS0601

[member723]

When I try to set the setpoint temperature like this:

action: climate.set_temperature
metadata: {}
data:
temperature: 20
target:
device_id: 565af3bb3fd4770578105984a6c0c1d2

The valve changes the local temperature

I think a mapping is wrong. Any Ideas how I can solve this.

Thanks for your support
