Dometic Penguin II A/c Heat pump installation

Question

Hi all, well I just finished changing out the old Dometic heat pump for a new 15,000 BTU model. All went well till I powered it up. The T-stat has power and so does the unit. When it is powered up the heat pump comes on and stays on. It does not switch to A/C. It also will not turn off when the T-stat is off. Any help will be appreciated greatly. Also are there dip switches on the unit on the roof as well as in the power module? When I received the unit and accessories there were no installation instructions included.

1. You still have the 5 button wall CCC tstat control?
2. IF SO, did you install the 12 button to 5 button control board on the new Penguin?
3. IF yes to question 1 and NO to question 2, That is your problem.
4. IF yes, to question 2, you did not install and wire the 12 to 5 button board correctly. Doug

Hi Doug I also have the new CCC2 T-stat installed. I removed the older T-Stat because I knew it wouldn't communicate properly.So everything is new.

I missed that. Are you stating you have a 8 x 8 inch galvanized box with a control board? If so, that means you really messed up. The Penguins come with a 12 button control board up in the HP box accessed from the top. So, it appears you are trying to utilize 2 different control boxes, which is impossible to do and I have never heard or seen that happen. You have to remove the original control module. Doug

Hey Doug, I don't follow, there are 6 wires coming down from the top. 2 yellow , 2 blue a red and a black. Plus two phone jack wires. If what you say is correct, what do these wires hook to? The same six wires off the multi zone module are the same color so I wired them color to color. I plugged the phone jack in for the T-stat and of course hooked up the 12VDC to the red and black wires to the module. All I get is heat. The T-stat flashes E5 and the temp set.Help!

Those 6 wires and the Phone type connectors come from the 12 button module mounted on the top area of the Penguin. Like I stated, you messed up big time. You will have to go on top and set the DIP switches on the module on top. Did the penguin NOT come with a 2 x 4 metal box with the 120 wires in it? Doug
