The really good Morningstar pwm regulators can divert power to elsewhere as the battery gets charged , instead of the power being reduced it sends the extra unneeded power to a load , usually something like a heating element for water .
It won't heat it up to scalding heat but will heat it up .
So don't worry too much about those two connections worry more about the others .
No idea who told me that garbage about the extra two wires with the light globe symbol and what they were for but I was only half right .
In some units you connect this one to a constant load to stop the battery overcharging , such as light or some type of load .
It apparently can also be connected to the battery , I've had cheap PWM units and reasonably good ones but always kept an eye on maximum charge and float charge .
I've never worried about putting a load on that connection .
Maybe Cuppa or threedogs will have a different way of saying it , but I'm sure that's basically what it's for .
