First Post. What else? Hydro Hot
I've enjoyed cruising irv2 for a few months since we bought an '06 Tiffin 42 QDP last fall. We had a couple 5th wheels previous and I have trucked so we weren't completely green. Anyway it has almost all been good but last weekend in the foothills of the Rockies we had no heat in the coach. Hydro Hot boiler was doing its thing but the first night only the bedroom heaters worked and the second night nothing.
Got home yesterday and started checking the net for clues as to what was wrong with our heating system. It has a Duo-Therm 3 zone thermostat and I finally found a website that had some answers. It is Sundancecustomerv.com. It said that if any zone is in a mode contradictory to other zones it will do nothing! I had 2 zones showing furnace but the third only showed cooling, and heat pump and off. Simple me thought that heat pump would be where to have it. WRONG! For whatever reason the Duo-Therm considers heat pump to be a version of A/C and therefore halts all operations if the other zones want furnace.
Full of hope I set the thermostat as instructed and went to the indicator panel hoping to see lights for 2 zones. No such luck! But I started jiggling the connector strips on the left side (I had the cover off) since the lower one had disconnected previously. When I wiggled the top one a light flashed and when I seated it better 2 zone lights came on! I went inside and heat was coming from every possible source. Is that ever a relief! And as simple as poor operation and a loose connector. Anyway I hope this experience might help someone else out. And thanks to sundancecustomrv.com
PS When we head to California in January it might be -20 F so we will need the heat.
