Hook up o to o/b, then in the installation programming set the change over valve to energize in cool. Then hook up w to aux. Good luck.

The 2nd combination is correct (w/ jumper). Wire nut or tape the blue wire. The snow flake shows it's going into cooling mode after a 5 min delay. If the AC is not coming on then the problem may not be the thermostat. If you don't have 24VAC between the red wire and the blue one the problem is at the furnace or it's supply. If you do, then check for 24VAC between the blue wire and Y on the thermostat(after the 5min delay) - if it's there the thermostat is calling for cooling. To check the heat, switch the thermostat to heat mode and use the W(instead of Y) on the thermostat(after the flame stops flashing).

The proper way to do it would be to use a small piece of wire stripped at the ends. Then use a small amount fo solder on each end to connect RC to RH. Or use a small piece of solid(stiff) wire and strip the ends. The wrap the ends around the connector and crimp them to make contact. I would not use a paper clip. A paper clip is not designed to carry 24volt current and could melt.

SOURCE: Wiring problem?
Yes to everything!!
You have it figured out!!
Just make SURE that the blue unused wire cannot touch any of the other wires, it will wreck your transformer in a split second.!
I hope that this will help you to solve your problem!
Thanks for using Fixya!!
