what thermostatic mixing valve is this

Janneke Member Posts: 1
Our thermostatic mixing valve is broken. The man that installed it in 2008 is retired. Does anyone have an idea in wich direction we have to search for a replacement?
We have consulted multiple repair technicians, but they don't know.

    looks close to a honeywell mixing valve, but check the dimensions for retrofit

    The whole assembly looks Euro based. Clever wiring connection :)

    Is it not mixing properly?
    Sometimes they just need to be disassembled and cleaned. There is not much inside, a spool, o-rings and a copper thermal "pill"

    It does look all European. Roth manifold, Danfoss actuators, grundfos pump.
    If I had to guess on the mixer, I would start looking to Roth for answers.

    What brand are the manifolds? They may be the supplier of the mix valve also or OEM it from another manufacturer.
