NOTE: Use of a transformer is
recommended if installing a dual fuel/
fossil fuel system with a CTK01* or
CTK02*. Failure to use the transformer
in the outdoor unit could result in over
loading of the furnace transformer.
Follow the thermostat manufacturers
recommendation on when an outdoor
transformer is needed. Do not
attempt to install an outdoor
transformer when using an inverter
type unit.
COMFORTNET™ COMPATIBLE FURNACE
WITH
NON-COMFORTNET COMPATIBLE SINGLE-STAGE AIR CONDITIONER
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 CTK0* kit. Remove the
red keying tabs from the on-board connector block and position both 4-position connector such that “1”, “2”, “R”, “C”, and “Y1”
positions are filled.
NOTE: The cooling CFM for this in-
stallation must be set up at the com-
municating thermostat through
