No mounting provision.
I bought this controller to replace an old Kenlowe one, it works well. One thing that was slightly annoying; there is now way to mount this controller, I’m sure when it’s being made they could’ve moulded a provision for a screw hole fixing.

Thermostatic controller
It was delivered promptly and is now fitted to the car. It would have been nice if instructions on electrical connections had been supplied but YouTube came to the rescue
