Chinese diesel heater controller operation?

[Versatile]

Hello, I have a 5kw heater diesel with controller # 1907.

It is 12/24 volt. I thought it was sat for 12v. With 12volt battery, I show 12.6 volts. I Get error code 006.

Code# 00= wrong voltage Code 06= low voltage.
Does this indicate the, wrong voltage/low voltage?
We set the clock first and then it scrolled down to time # and when we go to set it then we get the code 006



Videos say to scroll down to the password screen and use 1688. This will let you change the voltage.

The Battery icon is green. That means the battery is ok.

I know have a flashing exclamation mark next to the green battery symbol.

Any ideas?

Voltage will drop soon as a heavy amp load is pulled, no load, voltage bounces back up.

Especially so with a bank sized too small, or not true deep cycling type, and most especially once old and worn.

So, test with a known-good newish larger size battery.

I finally found a chart that says the exclamation mark is called a flickering light.
One flickering light says to increase voltage. Can you tell me the proper way to connect two 12 volt batteries to give it the 24 volts it wants?

here ya go

This is in parallel, same voltage, double the Ah

[john61ct]

This is in series, same Ah, double the voltage

OK, thanks. I have learned about the Ah. I will connect in series.

OK I hooked up in series to get 24 volts. Blows the fuse. Just like you are hooked backwards.

I took it out to my bus and hooked it up and pop and fuse is gone.
What am i doing wrong?

[john61ct]

what fuse where?

how can we know how you have the circuits wired?

maybe get a pro to look at your setup?
