SO when it don't calls for cool the n.c. contact wil send power to the low speed wire for heat (red to the fan motor which connects to the temperature control which cycle on the fan when calling for heat! HEY, you didn't give enough information, like WHAT___WHERE___WHEN__WHO ??? ____ model #-- name of unit-- age-- gas fire or electric ---upflw or downflow?
