Status message on aquatuner makes no sense

I'm running an aquatuner. It's cooling 40 C water to 26 C, so this is nothing abnormal, and it's sitting in a one tile deep bath of chilled p-water in a little sump with a temperate CO2 atmosphere. So this is also not abnormal. Everything around the aquatuner is cooler than it is.

It is not cooling the surrounding area, it is warming it.

I speculate that the status message and its tool tip are simply backwards.
