Then why voltage on battery is more than 13V ?

BTW, I have similar problem. Voltage on battery is steady 13.8V when
engine is running. But ClimateControl head shows 12.1V without electrical
load (radiator fan, a/c compressor, lights...). When radiator fan turns
on, voltage on CC head drops to 11.8V.

So, battery has 13.8V, but CC shows less. And dashboard voltmeter shows
about 13V (hard to tell what is exact value - something between 12 and
14V).

Things I suspect:

1. CC is not precise, and shows less voltage than it is.

2. Two red wires, that go from battery to system wiring.

3. ... ?
