Need advice on hooking up new thermostat please.

Hi All,

I bought a new thermostat that has a separate controller that's mounted near the HVAC equipment. Its not a complex system just a forced air gas furnace and A/C. There are 3 wires between the thermostat and the controller which is self explanatory. The other issue I have is the hookup from the controller to the furnace. I think I have it right but don't want to guess since I can't afford a new furnace:)

Anyway the markings on the furnace are as follows,

Y - Blue wire

G - Green wire

W - White wire

R - Red wire

C - White wire

The wires on the old thermostat are as follows,

Y - Blue wire

G - Green wire

W - White wire

RC - Red wire (there is a jumper installed to R)

I attached a schematic of the new controller. My plan was to disconnect the wires from the furnace, put the controller inline and distribute to the correct terminals.

So,

D1, R-2,C-3 will connect the thermostat to the controller.

Y-White wire

G-Green Wire

W1 (O/B)-white wire (this looked most correct)

R,RC,RH-Red wire. My question is there are jumpers across all three terminals. Do I leave those installed or take them out? Leave some and not others? Not too sure on that.

C- Goes directly to the A/C unit so its not really a component of this install.

If I had two dimes to rub together I'd hire someone but unfortunately for me I can't. Thanks for all the help.
