My RV has a Suburban furnace with 2 blue control wires and old analog thermostat,
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.
