Hi everyone, I’m new first post.
I have to change out 2 13500 ACs problem is the new penguin II only has one plug and my old duo therm domedic has two phone jacks and a bunch of wires which makes it not compatible. I have the five button Thermostat that works just fine. They even sold me a new thermostat that I really don’t need. So here I sit with a heavy duty trashcan bag covering the hole where my AC is supposed to be caulked down.
I believe there should have been a Control board that went from the Penguin II to the old wiring. Unfortunately I pick them up Friday and nobody there knew anything today or yesterday. It’s a 2004 double tree 5th wheel ducted system. So anyone that can possibly give me info I would surely appreciate it. Thanks in advance.

IF...you want to retain the 5 button you will need a new control board for each a/c...150-$200 each. Not a great solution.

The new thermostat is not only progamamble but you can see the numbers (larger) and if you get a remote temp sensor you can get much better cooling based on placement of the sensor.

Finding a "tech" to save the 5 button is difficult as most are plug and play jockeys. A friend is going through that experience right now. IF you decide to save the 5 button at least be sure you keep the boards that are in the new Penguins because one of these days the the adapter boards which are already difficult to source will be discontinued for sure.

Hi ! Welcome to IRV2! We're sure glad you joined us!

I did the same swap-out a couple of years ago. I just matched the wires up color for color. You definitely want to stay with the new CCC2 thermostat if that's what you got. The flat phone cable is for communications between the thermostat and the rooftop units. I'm not positive, but I think the jacks for the phone cables are paralleled, so it won't make any difference which jack you use.

Good luck, happy trails, and God bless!

How do you wire the new unit to the existing wiring? The penguin II has one plug. There is two phone cords and numerous wires coming out of the roof you got any ideas even if I upgrade to the new thermostat the wiring won’t plug and play as so to speak. I don’t wanna mess anything up. Thanks
