Sweet, thanks!


A) Take the black wire loose from 'R' at the air handler, because only the
red wire needs to be connected to 'R' there.

B) Now use this black wire to pass 'C' to the thermostat instead......if
there's no C terminal at the air handler then you need to connect it to the
transformer lead that is opposite R

( though C is probably not absolutely needed at the thermostat, without it
you will likely get poor battery life and /or none of the led indicator
lights will work )
