Solar controller question

I just bought a 100 watt RV solar kit from Amazon made by
Renogy. It has a 30 amp controller but all that came with it as far as instructions is a quick start guide which ,in places, says to see the manual.

Problem is no manual came in the box.

It shows how to hook it up and which colored flashing light means what but I see no way to adjust anything. It says it is safe for an AGM battery but it is my understanding you have to set a controller to match AGM charge rates.

Is it all preset? Should I trust it or buy a decent controller that has these capabilities?

Thanks .....DJ

Here is what I saw in my instructions today..

Hook up panel so it's making power from the sun and connect to your battery.

Hold that set button down for about 15 to 30 seconds until you see b2. b2 is the default value for VRLA or "Valve Regulated Lead Acid" batteries, otherwise know as gel cell.

Once "b2" shows, release and press the button again quickly and it will now show b3. b3 is for AGM battery charging. Let the charge controller sit for 30 seconds, and the light should go out and it will remember that setting, for AGM batteries. b1, for future reference, is for open vented, regular old Lead acid batteries like most of us use.

For your charge controller to have this feature, it should be v1.2 If you have v1.1, well, then, I can't say for certain.
