Yeah, I did some reading in your manual and a call to MorningStar would be a good idea. It appears that both the jumper and switch 1 are used to set the battery type.

Though there are voltage and time factors for equalization listed for AGMs
in the Battery Setpoints chart, the manual on page 14 clearly states:

"The auto equalize feature will administer an equalization charge
(flooded battery type only) every 28 days or if the battery
discharges too low the previous night."

This statement seems to contradict the chart.

Not exactly. I use this controller and the manual is correct. Switch 3 turns auto-equalization on and off, period. If that switch is off it won't ever equalize. Switch one changes the set points, so with the jumper removed you'll either be ON for AGM or OFF for Flooded. The reason they share the ability to equalize is simply because there are only 4 switches and they chose those battery types to be represented with the jumper removed. Also, some manufacturers do state you can equalize AGMs which is likely why they chose this combination, even though most say you should never do it.

This controller is much more than a simple charge controller, it has some great features if you use the software, including updating it's firmware. It also allows you to see all of the controllers active settings, what it's doing, and what's actually occurring. With my switch 3 off it never tries to equalize, it will just push to the bulk voltage, hold it, and taper off to float after the set time period. I've watched this with the controller connected to my laptop, it acts the way it's supposed to.

Leave switch 3 off, you'll be fine.

Hope that helps.

I satisfied myself that the Tracer 2210RN solar controller could be used with an AGM battery with the charge settings for the battery set for "sealed battery". I stress that this result came with absolutely no assistance from EPSOLAR who makes the Tracer. No info in the documentation, no info on their website and in spite of the "contact us", no replies to emails. There may be some out there to whom using the sealed battery for AGM may be obvious, but it wasn't to me. A simple yes or no as to whether or not the controller was suitable with AGM would have made the operation much easier.
The battery compartment is vented and cooling for the controller is improved by mounting a very small CPU fan ( about the size of a Can Looney) underneath the controller. It's powered by the Load output and draws .012A.

I've used Morningstar customer support and they were really good about responding to questions.

Noted Ron. I've already filed Morningstar away for future reference. I like that you can set individual charge rates and of course the support is a big plus.

I just received a reply from the manufacturer (EPSOLAR) of the Tracer solar controller. Not a prompt response, but a proper response none the less. So in the interest of fairness I am updating my previous posts. For the Tracer 2210RN solar controller. EPSOLAR recomends using the "sealed battery" setting for AGM batteries. They do not recommend using the "GEL battery" setting for AGMs. Although not stated in their reply, I assume that they consider the charge settings for the sealed battery setting the most compatible with AGMs. After some weeks of internet searching and advice from some of you here I had come to the same conclusion, but it's nice to hear from the manufacturer.

Here is a pretty good explanation of the differences between AGM/gel/flooded batteries:

Bill. Thanks for the link. That was about as good a write-up as I've run across and well written for the novice.
