Squirrel cage fan wiring

I see orange and black to connect to Line and Neutral. I see something connected to the Red lead (Idle) although it says NC.

I do see connections to T1 as 208 or 230 selectable. To me it looks like the motor is 230V but I don't know why they have a grounded center tap on the primary of T1 that says 208.

The red marked 208 is not grounded its a wire nut/capped. Hook the blower to 240 it will blow.

I have never seen that done on a drawing.

Here is the schematic that I am looking at:

Looking in the red box (labeled as "HIGH SPEED-COOLING LOW OR MEDIUM-HEATING") it appears to show the 2nd and 3rd "unused" serminals connected together and tied through the #1 connector, through a NC contact and to the #7 contact.
Perhaps I am misreading it?

The 2 unused terminals are not connected together. The schematic shows that the fan speed selector switch chooses between the high speed for the cooling or the medium or low speed (whichever you choose to connect up) for heating. Either terminal, but only one at a time.

Yes, this is a 230 volt motor which explains why it runs so slow.

As has been pointed out this is a 230 v motor...Some of these are 110 motors and some are 220/230 motors.
Measure the shaft size. RPM and buy a 110 v multi speed motor any you will be fine
