Identification of the product

[Neshco]

Hi,
is there some professional who can recognise this product?
I guess this is just some rebranded product and because there is no much manuals and support for particular model, that behind the scene is some well known brand of softener. Here are some photos of the product in use and board for easier identification.
Thank you.
