Good news, I called Truma and they are going to ship me the controller and temperature sensor. Should be here in a few days. It was about $400 with shipping. I just barely got my order in, they close the warehouse until January. Truma support is great too once you get ahold of them and if it's not a 'protected' part.

No, they would not. 😞 It's tough living out in the wilderness away from everything.

You are correct! Truma and Oliver will retrofit this furnace. Getting an appointment and driving across the country is another matter altogether. It's very straight forward.

For some reason, not for DIYers in North America. Europe and Australia, no problem. I can get parts from Europe, but I'm hoping to wrap it up. Truma is good stuff and I really wanted the Aquago Comfort Plus with water recirc. Truma said they wouldn't mess with the plumbing, but they would have installed the regular Comfort and the Varioheat. I would have had to go home and come back a month or two later. So I just did it myself and got the Comfort Plus. Olivers are easy to work on because of the space between hulls. I'll post all of my retrofit work when I'm done. The water heater install actually has gone pretty smoothly, but that's because it came with the controller. I should have been more careful with the furnace. I assumed it would work with a regular thermostat.

It's a super easy swap with the Suburban cassette furnace that is original. The newer Olivers have ducting and all that, so it makes sense that they don't retrofit those. I've confirmed with everyone that it's possible (and quite easy). After my experience with Truma directly trying to get an appointment for them to do it, I just decided to save time and do it myself. I was surprised that the unit doesn't just plug into a basic thermostat. So now I need a Truma control panel. Oliver service btw, continues to be outstanding. They reply almost immediately. I wish I had been close enough for them to do it, but they also have a pretty good lead time for service.

Hull #26. I recently purchased Hull #26 and took it almost straight to Elkhart so Truma could install a new furnace. Unfortunately, a week went by where they didn't answer my emails and when I got there, I waited outside for 25 minutes for someone to show up at the door. It's a ghost town. When I finally got to speak to a person, they said they were all headed to Germany for some corporate celebration and wouldn't be able to install it for a while (more than a month). Well, I don't live in Indiana, so I went home with no furnace. I then went to ebay and purchased a used Varioheat furnace. Everything looks great, but it appears the only way to operate it is with a Truma CP Plus control panel. I had hoped it would simply connect to my thermostat. Does anyone know if I can get a control panel separately, or better yet, does anyone have a diagram for the data cable that would allow me to directly trigger on/off for the furnace? Thank you for your help. -David
