Alde 3010 failure tempture registration

Alde 3010 failure temperature registration
After driving the caravan, I find occasionally, that the heat is registered incorrectly. The first time I experienced it, I had the heat on while driving. When I opened the door to the caravan the heat radiated out, but on the display it showed freezing temperatures. I have 2 thermostats. One by the bed, one in the living room. I pushed the selector between the 2 back and forth and suddenly the temperature was showing over 30 degrees from both.
I later found out that it was the thermostat by the bed that was showing wrong. But once it was corrected - see first video clip from 23.10.2022 and next video clip 17.11.2022, both thermostats run perfectly.
But now it's both that occasionally show wrong - see third video clip from 21.03.23 and fourth from 17.10.23. The last 2 times they "suddenly work". Both times the car was cold, I "just turned on the heat" and let Alde warm up and at one point approx. half an hour later, both thermostats where working perfectly again.

Efter kørsel med campingvognen oplever jeg af og til, at varmen registreres forkert. Føste gang jeg oplevede det, havde jeg varmen tændt under kørsel, da jeg åbnede døren til campingvognen strålede varmen ud, men på displayed viste den frostgrader. Jeg har 2 termostater. En ved sengen, en i stuedelen. Jeg trykkede vælgeren mellem de 2 frem og tilbage, og pludselig viste temperaturen over 30 grader fra begge.
Jeg fandt senere ud af, at det var termostaten ved sengen, der viste forkert. Men når den først fik korrigeret – se første videoklip fra 23.10.2022 og næste videoklip 17.11.2022, så kører begge termostater perfekt.
Men nu er det begge som af og til viser forkert - se tredje videoklip fra 21.03.23 og fjerde fra 17.10.23. De 2 sidste gange ”virker de pludselig”. Begge gange var vognen kold, jeg ”tændte bare for varmen” og lod Alde varme op og på et tidspunkt ca. ½ time efter, kører begge termostater perfekt igen.
