Replacement T-stat has one trminal marked "3" and one terminal marked "4". Which one gets black wire?

Existing T-stat has one terminal marked in (black connected) and one marked out ( blue connected).

Thanks.

Hi Steve,

As you can see from the part pictures







and the wiring diagram the thermostat has only two terminals. There is no difference which wire where goes.
