S9201A1010 INTEGRATED FURNACE CONTROL
APPLICATION
The S9201A1010 Integrated Furnace Control is used in
high efficiency gas fired warm air furnaces with an induced
draft blower and a combination hot surface igniter/flame
sensor. The S9201 provides:
•
sequencing of ignition and burner operation,
•
up to 5 trials for ignition before lockout, if initial lightoff
is unsuccessful,
•
ignition return if established flame fails during the run
cycle.
•
control of indoor blower motor operation, including
heating and cooling speeds,
•
control of the induced draft blower motor,
•
control of the humidifier, and
•
control of the electronic air cleaner.
The S9201 cannot be used with a vent damper.
The S9201 Integrated Furnace Control is intended for
residential furnaces only. Other applications require Hon-
eywell Residential Design Engineering review and written
approval. Contact your Honeywell Sales Representative for
assistance.
VOLTAGE: 24 Vac.
CURRENT DRAW: Inrush—0.32 A plus gas control current;
running—0.10 A plus gas control current.
POWER CONSUMPTION: Inrush—7.7 VA plus gas control
VA; running—2.4 VA plus gas control VA.
THERMOSTAT ANTICIPATOR SETTING: 0.10 A plus gas
control load. For VR8204 and VR8205, set anticipator to
0.6 A.
PREPURGE TIMING: 30 sec., nominal.
WARM UP TIMING: 36 sec.
TRIAL FOR IGNITION: 9 sec., nominal. Igniter is off 1 sec.
before end of ignition trial.
FLAME FAILURE RESPONSE TIME: 2.3 sec. max. with 5
µ
A flame signal.
FLAME CURRENT: 0.8
µ
A DC, min.
IGNITION TRIALS: Five, with 30 sec. purge between trials.
INDOOR FAN ON DELAY: 30 sec., fixed.
INDOOR FAN OFF DELAY: 90 sec., factory set; selectable
to 45, 60 or 75 sec.
GAS CONTROL: Any 24 Vac redundant gas control rated at
1 A or less. Honeywell VR8204 or VR8205 recommended.
COOLING CONTACTOR: Any 24 Vac contactor rated at 1 A
or less.
HOT SURFACE IGNITER: Norton Model 201 or equivalent.
NOTE: Igniter must meet the following minimum specifica-
tions throughout its life:
•
Igniter must reach 1000
°
C [1832
°
F] within 36 seconds
with 102 Vac applied.
•
Igniter must maintain at least 500M ohms insulation
resistance between the igniter leadwires and the ig-
niter mounting bracket.
•
Igniter must not develop an insulating layer on its
surface (over time) which would prevent flame sensing.
•
Igniter surface area immersed in flame must not ex-
ceed 1/4 of the grounded area immersed in flame. This
would prevent flame sensing.
•
Igniter current draw at 132 Vac must not exceed 5 A.
2. Check the ratings given in these instructions to make
sure the integrated furnace control is suitable for your appli-
cation.
3. Installer must be a trained, experienced service techni-
cian.
4. After installation is complete, check out operation as
provided in these instructions.
WARNING
FIRE OR EXPLOSION HAZARD.
MAY CAUSE PROPERTY DAMAGE, SEVERE
INJURY OR DEATH.
1. The integrated furnace control can malfunction
if it gets wet, leading to accumulation of explo-
sive gas.
•
Never install where water can flood, drip
or condense on control.
•
Never try to use an integrated furnace
control that has been wet—replace it.
2. Liquefied petroleum (LP) gas is heavier than air
and will not vent upward naturally.
•
Do not operate electric switches, lights,
or appliances until you are sure the ap-
pliance area is free of gas.
CAUTION
1. Disconnect power supply before beginning wiring
to prevent electrical shock or equipment damage.
2. If furnace control must be mounted near moisture or
water, provide suitable waterproof enclosure.
LOCATION
The integrated furnace control is mounted inside the
furnace wiring compartment. The location must provide:
•
Access to the field wiring terminals.
•
Operating ambient temperature between minus 40
°
F and plus 150
°
F [minus 40
°
C and plus 66
°
C], except
temperatures to 170
°
F [77
°
C] are acceptable for
occasional brief periods.
•
Relative humidity below 95% non-condensing.
•
Protection from water, steam or corrosive chemicals
that might be used to clean the appliance.
•
Protection from dripping water, such as from an over-
filled humidifier or from condensation.
•
Protection from dust or grease accumulation.
•
A barrier between line and low voltage field wiring
terminals.
MOUNTING
Select a location close enough to the burner to allow a
short, direct cable route to the igniter. The integrated furnace
control can be mounted in any position. Line voltage wiring
terminals must be in an enclosure separate from low voltage
field wiring terminals. The unit is designed to snap in to
predrilled holes in the mounting surface.
INSTALLATION
WHEN INSTALLING THIS PRODUCT…
1. Read these instructions carefully. Failure to follow them
could damage the product or cause a hazardous condition.
