Luna roadstar control panel help

[Moecol]

Hi can anyone please help by explaining what each button is for on this control panel thank you I am new to all this

Bottom left would be to select the engine/ van battery
Next to it on the right the habitation / leisure battery
Above those the V and A should show the readings in volts or amps of the battery selected below.
"W" Most likely the fesh water level in the tank.
Clock next to that pretty obvious "time" with settings for hours H and minutes M to it's right.
The tap symbols must be for the water pump but no idea why there is an internal and external unless there is a shower point outside.
The thermometer symbols. Inside and outside temperature ????

Thank you for your help

Outside tap symbol could be if there is an external pump attachment for filling the tank from a water barrel
