When I read about the setup process that people on this forum post for thermostats, I read that most people put the temp probes on the outside of the enclosure.

Why is this?

Wouldn't it work better if the temp probes were inside the enclosure so the thermostat can show what the real temp of the enclosure is?

I have a Herpstat 2 on its way to me now and I need to know how it should be set up and would like to know why it is set like this.
