Help required. I have Webasto central heating on my wide beam which I know works. Originally it had a small webasto controller which the previous owner had issues with so bypassed it with a Heatmeiser thermostatic touch screen controller. I used this a couple of times hence I know the Webasto works but the touch screen has "had it" hence it was almost impossible to switch off and then eventually on.
I just need a 12v controller, heating on heating off, NOT THERMOSTATICALLY CONTROLLED, not even timed that will switch the Webasto (20amp fuse) on and off at my will without paying a ridiculous £80 plus for a Webasto one.
Any suggestions please.
