NEUTRAL TERMINALS

These terminals connect 115VAC neu-
tral to the furnace control from the input
at the junction box of the furnace.
Additionally, spare terminals are provid-
ed for use with electronic air cleaners,
humidifiers and other accessories as
needed (Check the voltage rating of
your equipment.)
ELECTRONIC AIR CLEANER
(E.A.C.) OUTPUT (J8)
This output is used to energize an elec-
tronic air cleaner. The output will pro-
vide 1.0 amp at 115 VAC. This output is
energized any time the blower motor is
above 40% of maximum airflow capaci-
ty. Airflow below this value is not con-
sidered to be enough for a typical elec-
tronic air cleaner to perform properly.
For 1/2HP motors – Electronic air clean-
er is energized any time the blower is
above 480 CFM (1200 CFM x 0.4)
For 1 HP motors - Electronic air cleaner
is energized any time the blower is
above 800 CFM (2000 CFM x 0.4)
HUMIDIFIER OUTPUT (J8)
These outputs (two) are connected to
the contacts of a control-mounted relay.
In this sense, they are what are called
"dry" contacts. That is, they provide no
voltage, they are only used to close a
circuit. The contacts can be used to
close either a 24VAC or 115VAC circuit
either with a maximum of 1 amp cur-
rent. Details about the humidifier out-
puts and wiring diagrams can be found
in the section titled HUMIDIFICATION
AND DEHUMIDIFICATION of this doc-
ument.
15-PIN MATE-N-LOK CONNEC-
TOR (J1) (see Fig 28)
The 15-pin Mate-n-Lok style connector
provides connections for a variety of
inputs and outputs to the furnace con-
trol. For modulating furnaces with a
solenoid-controlled modulating gas
valve (HG or HH Fuel Codes) the 15-
pin connector provides power and con-
trol signals to the gas valve. Also, the
flame sense, pressure switches sense
and limits sense (Main Limit, MRLC
and HALC) are connected to the I.F.C.
through this connector. Reference the
wiring diagram for the furnace printed
in this document or on the inside of the
furnace blower door for pin assign-
ments for troubleshooting.
For troubleshooting purposes, follow
the wiring diagram and troubleshoot-
ing flowchart supplied in this manual
and on the inside of the furnace
blower door. Additionally, the pin
designations for the connector are
specified below:
