Sorry, I'm really new to this, I don't understand the right terminology. If anyone can help me understand, or at least give me a direction to help debug this, I'd be very grateful.

Please see the attached video. Starting from today, and seemingly out of the blue, my "heat pump" (the big box outside with a fan and tubes running into my house, at least I think it's called a heat pump) started, uh, stopping and starting. On my HVAC system, I have a black box labelled "aube" which keeps clicking? I don't know what any of those systems mean, and I can't find any documentation online.

This may be coinciding with the cooling system being turned on since today it started getting hotter outside, but my system has been working fine before now.

Does anyone understand what might be going on? Or can anyone advise on things I should check for this problem?

I'm so sorry, this has probably been asked a billion times already but i couldn't find a FAQ thread... I'm having issues with the water pressure in my camper and I'm checking everything. The docs that were provided with the camper aren't helping so I'm checking off things 1 by 1

Does this look like the right configuration for regular operation of a water heater?

Thanks in advance!
