Johnson Controls MR15DR230-2 user guide ?

Can anyone help with info on a Johnson Controls MR15DR230-2 controller. ?
I cannot access the menu's.
It's on a walk in frezzer and it just might be that the controller buttons are not working correctly - though they "feel" OK
I have googled it and got a few leads including Johnsons manual on the electrical panel including this controller.
This does provide info on what all the parameters are - but doesn't say how to access them (unless I am missing something ?)
Any help greatly appreciated.

BTW - does anyone know the legal situation on setting up an online database for any and all manuals that we collectively have ? (a free one I mean)

You have this file?

Hi Uri,
Yes this I have. But I can't find info on how to interrogate or change settings.
Maybe I'm just being dumb ?
I am at home sick at the moment and not thinking clearly perhaps ?

Hi weirdscenes.
I have managed to find some info from America which may help.
Please follow the link as the manual is to large to post on the forum.

Hiya Grizzly
Thanks a ton - exactly what I was after.
There are so many similar controls (up,down, enter, defrost) from many different makers and I can usually get into em - but this had me stumped
Looks like I was not allowing enough time for entry !

Again - many thanks
