A few forums said that's how you reset it. I will be calling Dometic and talking to them tomorrow.Re: Dometic digital thermostatUpdate - Got it wired. I was able to reroute the wires up to the control box. Routed the 2 furnace wires up from the old thermostat. Routed the 12V+ up to it and the routed the 3 wires that hook to the thermostat. Have it all hooked up but the thermostat doesn't display. I checked power and there is 12V at the small 12V screw so I know power is reaching the thermostat. I checked continuity between the 3 wires back to the control box and there is. No display. I have the Dometic Capacitive Touch thermostat. I called Dometic - No help at all. I think the thermostat is bad since I do not get a display at all. Any ideas?Re: Dometic digital thermostatNo, tried and tugged on the existing ribbon wire and it must be secured. What I am thinking is this. If you look at the thermostat you see the 4 wire plug. 2 blue 1 red and 1 black. That's the wires I need to get to the control box. That there is my 12v+, 12v- and my 2 blue furnace wires. I don't have any choice but to do a partial disassembly inside and get those wires up. I will also need the 12v+ constant wires. That I will have to figure out as I don't have that. I will have to run that from the 12V distribution block.Re: Dometic digital thermostatThe ribbon is the only wiring that runs up the control box a/c unit. The 4 wire connecter disappears somewhere else. I would have to get a schematic from Holiday Rambler but they have been bought and sold 3 or 4 times now.Re: Dometic digital thermostatHere's the picture of it. Re: Dometic digital thermostatI called Dometic and talked with them and he said I would need Kit #3313189.000 for my set up. So I ordered it but it looks a lot more complicated than others have posted. First, I do not have 12+ wires at my roof top a/c unit. All I have are the 120V, the plug from a/c (6 wires,) and the freeze sensor and the ribbon from the thermostat. There aren't any wires from the furnace or elsewhere. The kit wants 12+ to hook up to it but I don't have that. I don't have the 2 furnace wires either that are needed to hook up. The back of my thermostat had the ribbon connector and another connector with 4 wires from it. I have no idea where the 4 wires go. The ribbon came out by the old analog box in the a/c. I really don't want to have to disassemble half the interior to route new wiring. Thoughts anyone?Re: Dometic digital thermostatSingle roof top a/c and single furnace.Re: Dometic digital thermostatNot sure if it matters, but there 2 other thermostats in the travel trailer. One up front in kitchen and one in the back bedroom. I don't care if those work or not. Will that matter?Re: Dometic digital thermostatI think this worked. Here's a picture of the control unit. Re: Dometic digital thermostatDigging up this old thread. I have the analog set up in my 94 Holiday Rambler and the t-stat has failed. I read through the topic and the kit that was linked on the first page is that what I need or are there others depending on what I have. If I could figure out how to post pictures...... https://flic.kr/p/Tj2ucj
