Hello.The thermostat needs a COMMON wire.The letter C on the back of the thermostat.In the unit it runs there is a COMMON connection for that reason.I hope there is a spare wire strand to use because a lot of thermostats don't need a common to work (uses battery)but honeywell does.

Hi,
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!!
