Hi , I am currently installing a truma therme TT2 water heater in my self build campervan, I have run all the water pipes to were they have to go and run the wiring from the heater up to the consumer board , the problem I have now is the switch, I don't know where the wires have to go it has green, yellow, white and brown wires coming from it, I have looked on line for any wiring diagrams but have had no luck , is there anybody out there that can help, thank you, Ian.
