Another potential issue (or perhaps my lack of understanding on how to set it up)

I have My original classic one that has the battery temp sensor attached to it and the WBJR attached to it . Now I have the 2nd classic that has no battery temp and no WBJR.

In the setting for follow me you have two tick boxes (follow me) and (follow masters battery sensor)  The issue is ...who is the master? is I seem to recall being told there is no( master/slave) arrangement and the master is just the classic the reaches absorb or float first triggering the other?

If this is true then what happens if the classic that dosn't have the temp sensor reaches float first (becoming the master ) and the classic with the temp sensor starts following it ?

Also on the classic without the WBJR or temp sensor. It also has a box in its setings (use WBJR to trigger end amps) do I tick yes? as in can it use the other classics WBJR or just don't tick it and assume the classic with the WBJR will always be the one triggering float as loads + end amps setting usually will trigger first.

So what boxes should be ticked (remembering that both classics have the same options to tick) for my configuration?...two classics and only one classic has temp sensor and WBJR.

OQLD,  only one classic has temp sensor

Why?  didn't the second CL have a RTS?

Logically, I don't have a flolow me set up, if you clicked #1 's 'follow me' box it should the be the leader of the parade, especially if you tick 'FOLLOW MASTER' in CL #2.

I guess boB will chime in... if that is wrong logic...

I do have a 2nd temp sensor though my understanding is you only use one as you want both classics to have the same readings (share the sensor)

there is no (follow master) option just follow me in both classics.

So for (master/slave) that's the confusing bit as from what I can take from the video tutorials  there is no (master/ slave)  assignment just two classics doing what ever the other one triggers first. Though that makes it a bit funny. I would assume I want the 2nd classic to follow the original one that has the WBJR and temp sensor ....that's the bit that needs clarification.

right Kurt, you want the Classic with the RTS to be the MASTER. 

In COLD weather the non RTS Classic would reach V-Float before the one with the RTS , and the opposite in hot weather.

or is that in reverse?   ??


boB, another time out on this thread

But as I said there is no (master/slave) allocation ...no option for this just a tick box called ( follow me) and the way they explain it and the option they give you allow both classics to become the (master) just what ever one reaches absorb or float first triggers the other to do the same.

My assumption is that both classics need to be in (follow me mode) and only the classic without the battery temp sensor needs the (follow masters battery temp sensor) box ticked.

The confusing bit about that is what if the classic without the temp sensor was the master (triggered float first) If that means its the master now then it cant follow its own temp censer as it doesn't have one :o  it could be in the wording and ticking (follow masters BTS) automatically makes the classic with the sensor the master :o Its not very clear.

There is an option that sets one as the BTS master. Not exactly sure where but it was in there.

BTS=Battery Temperature Sensor just for clarity.

The only option there is is this........ (follow masters battery sensor) But considering they can both essentially become the (master) by reaching absorb float first then the assumption is that the CC without the BTS could be the master.


So I assume as far as the BTS settings are concerned by ticking the box (follow masters battery sensor) on the controller without the BTS that it will always follow the other CC's BTS even if for some reason it got to float or absorb first and was the master CC (master) It's self.

Kurt;

Mine seem to do this. My "BTS Master" Classic is on Solar and the other Classic is on a wind turbine that does not often make much power. That may make them act different as the Solar is usually the one making the changes and wind just follows.

I was told that there is no "Master" in Follow Me but I recall reading there are BTS master and slaves and there is some kind of BTS network but not exactly sure how that works?

Maybe one of the Pros will respond?

Correct.

No. Still, whoever triggered first makes everybody do the same charge stage.

Master BTS and follow BTS is only for the BTS information.  You could however have many classics
in follow me and say, 2 or more BTS's and those set to MASTER and that BTS would be the Master BTS
from that classic until the next classic with BTS in the follow me chain.
