HAPPYHIKER Report post Posted February 4, 2012 On these cold mornings my wife and I always lay in bed and debate who is going to get up and turn on the furnace....I always lose. After checking with Lazydays parts department, I was told that Dometic and others do not make a Climate Control System with a built in timer. Commonplace in houses but apparently not in RV's. Sharing a solution that I implemented.....I modified a cheapie timer, keeping the timer function intact but separating out the mechanical switch which I used to parallel the existing Dometic switch within the climate control uint. We can now set the time to come on and the time to go off for any function within the control unit plus the existing Dometic switch is still functional. I finally won the debate at a cost of less than $10. If anyone would like further details I would be happy to provide them. Happyhiker...2002 Allure 40 ft.
