Four wires are required between the furnace and thermostat. Two
wires are required between the furnace control and single stage air
conditioner. For this system configuration, the “Y1” terminal on
the integrated furnace control becomes an output rather than an
input. The “Y1” connection to the outdoor unit is made using both
4-position thermostat connectors in the CTK01AA kit. Remove
the red keying tabs from the on-board connector block and posi-
tion both 4-position connector such that “1”, “2”, “R”, “C”, and “Y1”
positions are filled.
