It is still strange to me.
There should be OBD-II data for the engine coolant temperature.

The Ford thermostat is listed at 190'F.
The car never gets more than 191'F infered with ICE continuously on, which is based upon CHT of 233'F actually measured.
OK, it's 190F thermostat. The Prius one is 82C(180F) specification and there is higher one which is 88C(190F) specification.
I suppose that one is used on your FEH and it starts to open at 190F and fully opened at 205F, therefore the typical coolant temperature is approximately 196F.
Again, if your heater is turned ON, it's another story.
