@Ayjay I have installed the comfort controller and it’s definitely more user friendly and has more functionality than the PU27. I was surprised how small it is and I have attached a few photos to compare against the PU27.I was thinking of getting one of those myself and would be interested to know what you think once it’s installed
I also moved the control to a different part of the van by purchasing an extension cable.
The unit is definitely a straight swap for the PU27.
There is a YouTube video available by Owen Cox which shows all the functions and I would recommend you have a view before purchasing.
Also Autoterm currently have 10% off.
Don’t buy from PF Jones as they take your money and then tell you a few days later that they have no stock.
