CAUTION
When servicing controls, label all wires
before disconnecting. Wiring errors can
cause improper and dangerous operation.
After servicing is completed, always verify
proper operation.
The unit wiring harness is an integral part of the furnace.
Field alteration to comply with electrical codes should not
be required.
Power supply to the furnace must be NEC Class 1, and
must comply with all applicable codes. The furnace must be
electrically grounded in accordance with the local codes or,
in their absence, with the latest edition of the National
Electrical Code, ANSI NFPA No. 70 and/or the CSA C22.1
Electrical Code. A fused disconnect must be provided and
sized in accordance with the unit maximum overcurrent
protection.
THERMOSTAT REQUIREMENTS
3/4"
A two stage thermostat must be used with this furnace. A
two stage furnace will have both "W1" and "W2" terminals.

system and a two stage heating/one stage cooling system.

If the thermostat has "Y1" and "Y2" connections and a one
3,400
3,100
stage cooling system is used, connect "Y" on the furnace
2,600
control to "Y1" on the thermostat.

CONTINUOUS FAN OPERATION
1,500
The two stage furnace control will energize the low heat
circulator fan speed when the fan switch on the thermostat
is turned to the "ON" position. This fan speed will provide
circulation with less electricity than conventional single
stage equipment.
NOTE: For two stage heat only (no cooling) applications, the
continuous fan speed may be increased by placing a jumper
between "Y" to "G". Thermostat must have a "G" terminal to
make use of this feature.
