I have this Easy start select control in my camper and it is for airtronic heater, but it only stays on for 60 min I have tried to change the program but with no results. Can you suggest a replacement controller Zac
Please see image showing workshop menu. It is possible to enter the workshop menu to adjust runtime above 60 mins ( section 4.1) but not possible to switch off the time restriction completely if you have a water heater. Only with an air heater is it permissible to not have a defined runtime.
