Help Needed with a Suburban Furnace with new Digital Thermostat

My RV has a Suburban furnace with old analog thermostat with 2 blue wires, one blue went to the (R)red and the other blue wire went to the (W)white of my old thermostat.

I know the old thermostat handle the blue wires like switch, open/close.

But with my new digital thermostat the manual said connect the (W)white wire to the furnace and the (R)red to +12vdc.

So do I just connect one of the blue wires to the (W)white wire on the thermostat, which doesn't make sense?

Or do I need to add a relay or something.

Any help would be appreciated.
