Can you identify this product?

[chall]

Sorry to post a question not directly related to beer on this forum, but perhaps someone can help me out. I am attaching a picture of a gadget that came to me in a bundle of used equipment. I suppose it must be some model of Auber temperature controller. Does anyone know how I would go about finding the manual on this item? There are absolutely no markings on the case beyond the attached photo of the face plate. The thermocouple was not included.

Any help would be greatly appreciated.

Thank you,

Charles.

It could be SYL-1512A or SYL-1612B. You can check the input voltage for the controller to identify which controller it is.
