Configure Smart Thermostat-Valve TS0601

I connected the Thermostat-Valve (ZTRV-ZX-TV02-MS manufactured by Moes )to ZHA, that worked fine.

The device exposes a switch. What´s that switch for?

In the standard Thermostat Card, it is possible, to setup ab “Preset” (values: None, Complex, Away, Eco, Boost)
How do I define the preset?

I have seen a video, in which then TS0601 was connected via Zigbee2MQTT.
In this configuration it exposes a lot more Entities.
Is it possible, to get this enties in ZHA too?

Thanks
Michael
