Unsure which Grohe model and the shower is too hot

[pb2501]

Hello all!

I just bought the house and the shower temperature is too hot no matter the location of the temperature control knob. I am unsure what model of Grohe this is.

The water heater temperature was set too low when I moved in. The water was only getting luke warm thoughout the house. I increased the water heater temperature. The faucets throughout the house can now get hot. The only problem now is that the master bathroom shower is way too hot. I thinking that the temperature control valve needs to be recalibrated.

Also how do I remove the handle?

Thanks in advance.

Thank you! There is a screw on the handle that is covered by a threaded ring.
