This was to replace my old Hansgrohe Solaris handle and trim which is now unavailable. The one sent seems similar but the handle is different from the one I wish to replace and also different from the one pictured on the manual cover.
The Solaris handle should have a middle notched knob that regulates the temp while outside handle regulates flow. I don't know how to regulate temp as there is no knob to turn just a siny circle of metal. Please advise as this seems to be another model's handle.
