Getting more info on device settings

Hi, I am new to HA and I think I am trying to run before I can walk.
My setup is a Raspberry PI 4 with a Zigbee dongle and I want to control the boiler and radiators with HA, using Tuya TRVs and thermostats in each room, but just got my first TRV paired and I have 3 switches, 2 temp settings, and a Binary input, but I really need to know what each does? is there any reference documentation that will tell me more?
TZE200

I would suspect the usual.

Set Point
Calibration Off-Set

Open Window
Child Lock
Manual / Auto
On / Off
etc

Relative Humidiy
Average Temperature

Have you tried setting each option and seeing what changes on the TVR. Dont they usually have a screen and booklet explaining the icons?
