Hey! I am not an expert in heating but I wanted to exchange my old thermostats. I chose bht-002 but I am not sure which variant I should choose. GA, GB, or GC? I have 230V Schutz 5000655 valves. If I understand it correctly, the valve is closed without voltage. It controls the water underfloor heating. The water is heated by a gas boiler.
I got mine yesterday and chose bht-002 GC for our gas boiler.
It was switched via a relais with its own phase so I choosed the one with potential free relais.
My recent experiences on these thermostates: If you by them now they will mostly have newer firmware which isnt flashable ota via tuyaConvert!
But wired flashing works fine
As you are using actuators you will need bht-002 GA to power these.
Have a look at the description pictures
