Truma CP plus Reset Procedure

[Tony and Rhonda]

Out Truma CP plus 'sees' our AquaGo but doesn't see our Truma A/C. I've found other posts about resetting the CP using the procedure in the manual but I can't find the procedure in the manual we have. I think I remember reading it in another post but can't find it now.

I'm not sure we have the complete CP manual so would someone please post a link to the CP manual which has this information or the post with the steps to reset the CP.

Thanks,

Tony

I have had this problem on and off.  First time was a wiring problem from the factory which was resolved.  With that resolved, if you forget that the inverter is off and you are not on shore power, of course, you wont see the ac unit.  I find that sometimes it takes awhile after the inverter is on for the ac to "reappear".  Must say i havent figured it out yet since it comes and goes.  Certaintly a communication error is suspect and probably a connection or wiring issue up in the ac since the furnace and water heater are reliably present in cp plus.

Here is the Cp plus manual (2023 version - yours may be different).  Although resetting is a recommended step, it has never resolved my CP plus issues.

@FloraFauna Thanks for the manual. Looks like the one I have. Our Truma equipment  was installed in 2023.

Are you on shore power or have the inverter on? If you don’t have one of these the AC will not show as it does not have enough power to run it. That is when we see the AC not show in the CP panel (we inverter is off and we are not plugged in).

We were on shore power. AC worked with the remote, just didn't appear on the CPPlus. The AquaGo is visible and operates from the COPlus.

The AC did appear on the CPPlus when we bought the trailer (used) and now doesn't.

If on shore power I would try a a reset of the CP. 

Go to Gear icon, press button -> scroll to "reset" and press -> you will see "pr reset", press button.   UI will flicker.
