SEQUENCE OF OPERATION

NOTE

: Furnace control must be grounded for proper operation or

control will lock out. Control is grounded through green/yellow
wire routed to gas valve and manifold bracket screw. Using the
schematic diagram in Fig. 73, follow the sequence of operation
through the different modes. Read and follow the wiring diagram
very carefully.

NOTE

: If a power interruption occurs during a call for heat (W),

the control will start a 90

−

sec blower

−

only ON period two sec after

power is restored, if the thermostat is still calling for gas heating.
The Amber LED light will flash code 12 during the 90

−

sec period,

after which the LED will be ON continuous, as long as no faults
are detected. After the 90

−

sec period, the furnace will respond to

the thermostat normally.
The blower door must be installed for power to be conducted

through the blower door interlock switch ILK to the furnace

control CPU, transformer TRAN, inducer motor IDM, blower

motor BLWM, hot

−

surface igniter HSI, and gas valve GV.

1. Heating

See

Fig. 40 for thermostat connections.)

The wall thermostat “calls for heat,” closing the R

−

circuit. The furnace control performs a self

−

check, verifies

the pressure switch contacts Collector Box

LPS and Hous-

ing Pressure

HPS are open, and starts the inducer motor

IDM.

Inducer Prepurge Period

−

As the inducer motor IDM

comes up to speed, the collector box pressure switch con-

tacts LPS close to begin a 15

−

sec prepurge period. The

inducer housing pressure switch contacts HPS are ignored

until one minute after the gas valve closes.

Igniter Warm

−

At the end of the prepurge period, the

Hot

−

Surface igniter HSI is energized for a 17

Ignition Sequence

−

When the igniter warm

−

up period is completed, the main gas valve relay contacts

GVR close to energize the gas valve GV, the gas valve

opens, and 24 vac power is supplied for a field

−

installed

humidifier at the HUM terminal. The gas valve GV permits

gas flow to the burners where it is ignited by the HSI. Five

sec after the GVR closes, a 2

−

sec flame proving period be-

gins. The HSI igniter will remain energized until the flame

is sensed or until the 2

−

sec flame proving period begins.

Flame

−

Proving

−

When the burner flame is proved at the

flame

−

proving sensor electrode FSE, the furnace control

CPU begins the blower

−

ON delay period and continues to

hold the gas valve GV open. If the burner flame is not

proved within two sec, the control CPU will close the gas

valve GV, and the control CPU will repeat the ignition se-

quence for up to three more Trials

Ignition before go-

ing to Ignition

−

Lockout.

Lockout will be reset

automati-

cally after three hours or by momentarily interrupting 115

vac power to the furnace, or by interrupting 24 vac power

at SEC1 or SEC2 to the furnace control CPU (not at W, G,

R, etc.).

If flame is proved when flame should not be present, the

furnace control CPU will lock out of Gas

−

Heating mode

and operate the inducer motor IDM until flame is no longer

proved.

Blower

−

On Delay

−

If the burner flame is proven, the

blower motor is energized on HEAT speed 25 sec after the

gas valve GV is energized.

Simultaneously, the electronic air cleaner terminal EAC

−

is energized and remains energized as long as the blower

motor BLWM is energized.

Blower

−

Off Delay

−

When the thermostat is satisfied, the

−

W circuit is opened, de

−

energizing the gas valve GV,

stopping gas flow to the burners, and de

−

energizing the hu-

midifier terminal HUM. The inducer motor IDM will re-

main energized for a 15

−

sec post

−

purge period. The blow-

er motor BLWM and air cleaner terminal EAC

−

1 will

remain energized for 90, 120, 150, or 180 sec (depending

on the blower

−

OFF delay selection). The furnace control

CPU is factory

−

set for a 120

−

sec blower

−

OFF delay.

Cooling Mode

The thermostat “calls for cooling.”
See Fig. 40 for thermostat connections)

The thermostat closes the R

−

and

−

Y circuits. The R

−

circuit starts the outdoor unit, and the R

−

and

−

Y circuits start

the furnace blower motor BLWM on COOL speed.

The electronic air cleaner terminal EAC

−

1 is energized with 115

vac when the blower motor BLWM is operating. When the

thermostat is satisfied, the R

−

and

−

Y circuits are opened. The

outdoor unit will stop, and the furnace blower motor BLWM will

continue operating on the COOL speed for an additional 90 sec.

Continuous Blower Mode

When the R

−

G circuit is closed by the thermostat, the

blower motor BLWM will operate on HEAT speed. Termi-

nal EAC

−

1 is energized as long as the blower motor BLWM

is energized. During a call for heat, the blower BLWM will

stop during igniter warm

−

up (17 sec), ignition (7 sec), and

blower

−

ON delay (25 sec), allowing the furnace heat ex-

changers to heat up more quickly, then restarts at the end of

the blower

−

ON delay period at HEAT speed.

When the thermostat “calls for cooling”, the blower motor

BLWM will operate at COOL speed. When the thermostat

is satisfied, the blower motor BLWM will operate an addi-

tional 90 sec on COOL speed before reverting back to con-

tinuous

−

blower (HEAT speed).

When the R

−

G circuit is opened, the blower motor

BLWM will continue operating for an additional 5 sec, if no

other function requires blower motor BLWM operation.

Heat Pump

When installed with a heat pump, the furnace control auto-

matically changes the timing sequence to avoid long blower

off times during demand defrost cycles. When the R

−

Wand

−

Y or R

−

and

−

and

−

G circuits are energized

the furnace control CPU will continue to turn on the blower

motor BLWM at HEAT speed, and begin a heating cycle.

The blower motor BLWM will remain on until the end of

the prepurge period, then shut off for 24 sec then come back

on at HEAT speed. When the W input signal disappears, the

furnace control begins a normal inducer post

−

purge period

and the blower switches to COOL speed after a 3 sec delay.

If the R

−

and

−

and

−

G signals disappear at the same

time, the blower motor BLWM will remain on for the se-

lected blower

−

OFF delay period. If the R

−

and

−

signals disappear, leaving the G signal, the blower motor

BLWM will continue running the blower motor at HEAT

speed after the selected blower

−

OFF delay period is com-

pleted.
