DuoTherm Penguin Replacement; Specific Questions

[USMCRET]

Gents, thanks for all of your helpful inputs. After a bit of waffling on replacing one or both units, I decided to replace only the one unit and I also ordered the adapter card. I hope to have the repair completed by mid November.

Good luck!

I replaced one of my ducted duo therm 15K heat pumps last spring. ( the front one)with a new Penguin II AC unit after going round & round with Domitek letting me know ducted units for Newmars were no longer available. I hooked up Penguin with my old board & 5 button thermostat.After some aluminium tape duct modifications we've been comfortable during our summer trips. Last night it was 44 degrees, and neither the rear heat pump,or the furnace worked. I checked all the breakers & fuses , to no avail. Evidently something in the communication daisy is amiss. Any suggestions? Thank you, Art.

Hi, not sure but when I changed my rear unit , I had same problem and read online that I needed to look at the board to make sure the switch inside was on for furnace. Just switched it over with small screwdriver being careful to not damage it. Check to see if yours is in on position. Hope this helps.

How did you get to talk to a Dometic Tech type?? All I got was a directory of dealer Repair facility

OK, I'm back on task now. I just looked at the wiring under the new and old units and have just one question: There are two phone jacks and apparently only one phone cable running to the rear unit. I assume this is correct, but I want to check with the body of knowledge here to confirm this. I also understand it makes no difference which jack the cord is plugged into.

Headed out to install the adapter board now. Cover me. I'm going in.

The second phone jack is for daisy-chaining additional AC/HP units. I think the newest boards can control up to five.

In spite of what I have read here and elsewhere, my new HP unit is not a direct replacement insofar as the lag bolt hole alignment is concerned.

I put the adapter card in, wired in the 115v, hooked all the other wire connections up, and began to bolt it down.

I put the two rear bolts in and then began to put the right front bolt in when I discovered the holes weren't lining up. My ruler shows that there is 13" between the front bolts on the old unit, and only 10" or so on the new one. Looking at the unit's centerline, that's cockeyed too, so I'm going to have to basically re-do the bolt pattern all around.

That's disappointing. It would have been so much easier if everything lined up. Oh well, I'll get back to it tomorrow. This pinched nerve in my back is screaming hot and making me bark at the moon.

Happy dance here!
