What colour should the fan switch on the thermostat be? Ive been told its green, but i always thought it was orange?

 

car rememebr m8 but when i changed mine a few months ago the new one was a different colour to old one if that helps. And it works fine even tho ive wired an additional overide switch that i dont use now it works properly!

 

orange is cvh green is diesal
