Truma CP Plus Corrupted Display

[Rivernerd]

The Truma CP Plus wall control display in our Hull #1291 has become corrupted.  See attached photo.   It should read:  "P 12:54", denoting 12:54 p.m.

Since we took delivery of the trailer last November, the Truma CP Plus wall control has worked well to control the furnace, AC and Aquago water heater.  The display was always crisp.  But, on a recent trip, the display suddenly appeared corrupted.

Has anyone else  had this issue come up?

We have only had our CP plus display two weeks ago tomorrow. No issues with it. I would file a work ticket with Oliver. I hope it gets resolved quickly for you. Maybe try a battery disconnect for a full reset?

Low probability but you can try to reset it by powering it off and then on again, press and hold the round button until the display goes off, then turn it back on; otherwise give service a call.

While camping I tried:  (1) turning the CP Plus off, then on again and (2) turning off all 3 of our batteries, then turning them off again and (3) doing a Reset following Truma's instructions.  None of the three methods worked.  So, once I got home, I submitted a service ticket.

Since I wasn't using any of the Truma appliances at home, I turned the CP Plus off.  A few hours later, Hannah Dowdy from Oliver responded to my service ticket by recommending a Reset.  I decided to try that again.  To my surprise, when I turned the CP Plus back on, the display read correctly!  No Reset was required.

It would appear that turning the CP Plus off, then waiting several hours, resolved the display issue.

Hope this helps if anyone else encounters this quirky issue.
