NOTE: Wire routing must not interfere with circulator blower
operation, filter removal, or routine maintenance.
As a two-stage furnace, the furnace integrated control
module provides terminals for both "W1" and "W2", and
"YLO" and "Y" thermostat connections. This allows the
furnace to support the following system applications: 'Two-
Stage Heating Only', 'Two-Stage Heating with Single-Stage
Cooling', and 'Two-Stage Heating with Two-Stage Cooling'.
Refer to the following figures and table for proper connec-
tions to the integrated control module.

system".
This furnace is equipped with a 40 VA transformer to facili-
tate use with most cooling equipment. Consult the wiring
diagram, located on the blower compartment door, for fur-
