Solar Panel Regulator

[earlybird]

I have A Solsum 5.0X regulator, which has 3 pairs of +/- terminals. Those for the panel and the battery are obvious from the symbols, but the third pair is marked with a symbol I can't interpret, it just might represent a relay. Can any-one tell me what the terminals are for?

I seem to recall it's for connecting a load that is isolated if the voltage drops below a certain threshold (10,5V?).

Danera has got it! IIRC it is a symbol for a lamp.

I cannot find manual on line but are they the terminals for a (the ) load which is subject to the "over discharge protection" feature .

Diagram HERE

Higher models in the range refer to a "low voltage " (LVD) feature that disconnects the load if the volts fall below 11.1volts and reconnect it when they rise to 12.6 again.

Thanks very much, mystery solved.
P.S. I'd tried Google without much success!
