This is the controller model I got with my heater (not my photo, just same controller) - Except mine has chinese writing, not english.

looking at the sequence and combinations of buttons, it seems like in functionality terms it is the same as the LCD controller that seems pretty common (this one ...)

I think when I said I installed a heater with a rotary dial it was assumed it was THIS one ...

That seems to be the most popular controller that is supplied and looks nice and straightforward. The one I fitted
didn't have the buttons or the illumination on the dial, it was super-basic with just a dial.
Anyways, sussed out the controller eventually, but just a heads up for anyone looking at these heaters ... Mine was faulty from new

Got an E-06 code which is a fan error. Took it all apart and messed around with it (really should not have to do this with a brand new item!) and got it working. The cover for the ECU had been clipped on slightly too forward and was fouling the fan edge. Adjusted position of that.
Also had bits of bent cardboard being used as corner shims at the heat output end which was not too impressive. Guess it is a matter of getting what you pay for! So put cardboard back where it looked like it came from and reassembled the heater and seems pretty good in fact.
The Eberspacher I fitted 18 months or so ago was certainly a better product, and the chinese heater fitted on Sunday was also working out the box with no problem other than ages to prime.
