IMPORTANT NOTE
As a two-stage non-communicating furnace, the furnace inte-
grated control module provides terminals for both “W1” and “W2”,
and “Y1” and “Y2” thermostat connections. This allows the fur-
nace 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 for proper connections to the integrated control
module.
Low voltage connections can be made through either the right or
left side panel. Thermostat wiring entrance holes are located in
the blower compartment. The following figure shows connec-
tions for a “heat/cool system”.
This furnace is equipped with a 40 VA transformer to facilitate
use with most cooling equipment. Consult the wiring diagram,
located on the blower compartment door, for further details of
115 Volt and 24 Volt wiring.
NOTE: Use of ramping profiles requires a jumper between
Y1 and O.

24 V THERMOSTAT CONNECTIONS
Low Voltage Connections with Auxiliary Terminals
The auxiliary contacts are shipped with a factory installed
jumper. As an option, the auxiliary contacts may be wired
to a normally closed float switch. In the event of open
contacts, the furnace will be disabled until the condition is
corrected. These are 24 volt terminals fed internally, do not
apply another voltage source to these terminals.
