Profitec Pro 700 heating / PID questions

Hello all!
Happy Sunday!

I just received the profited pro 700 and have been exploring the features. Pulled some reasonable shots, I think :D

I'm a bit confused about how the temperature sensing and PID-loop work in profitec pro 700 or in dual boilers in general.

I turned the steam boiler off last night. This morning while making my espresso, I noticed the PID display showing a steady increase of temperature on the steam boiler to about 95 - 99 degrees Fahrenheit. I wonder why.

The brew temperature was at 202F.

Is this an expected behavior?
Shouldn't it just stay at room temperature (between 60 and 70F)?

The steam boiler is pretty close to the brew boiler so the brew boiler is just heating the space enough to cause the steam boiler to increase in temperature. If I remember correctly, there's also an offset so the boiler will never actually get to room temp thought that may be the brew boiler and not the steam boiler.
