SAFETY CONSIDERATIONS
CAUTION!
Only trained personnel should install or service heating equipment. When working with heating equipment, be sure to read and

ELECTROSTATIC DISCHARGE (ESD) PRECAUTIONS
Use caution when installing and servicing the furnace to avoid and control electrostatic discharge. ESD can impact electronic components. These
precautions must be followed to prevent ESD from hand tools and personnel. Following these precautions will protect the control from ESD by
discharging static electricity buildup to ground.
1. Disconnect all power to the furnace. Do not touch the control or the wiring prior to
discharging your body’s electrostatic discharge to ground.
2. To ground yourself, touch your hand and tools to a clean, metal (unpainted) furnace
surface near the control board.
3. Service the furnace after touching the chassis. Your body will recharge with static
electricity as you shuffle your feet or move around, and you must reground yourself.
4. Reground yourself if you touch ungrounded items.
5. Before handling a new control, reground yourself; this will protect the
control. Store used and new controls in separate containers before
touching ungrounded objects.
6. ESD damage can also be prevented by using an ESD service kit.
INSTALLATION
Remove Existing Control:
1. Turn thermostat to OFF position or set it to the lowest possible setting.
2. Turn OFF electrical supply to furnace.
CAUTION!
Failure to turn off gas and electric supplies can result in
explosion, fire, death, or personal injury.
3. Label each wire with the correct terminal designation.
4. Disconnect the power supply and the thermostat lead wires from the existing
ignition control.
5. Disconnect any other line/low voltage, accessory wire and ground leads from
the existing ignition control.
6. Remove any screws and any other fasteners, and the old ignition board.
Install New Control:
1. Ground yourself properly before installing the new ICM286 control board.
2. Mount the new control using any screws and fasteners previously removed.
3. Connect all line/low voltage, accessory, thermostat and ground wires.
4. Verify the sequence of operation.
Main Operation:
On the application of power, the control will continuously monitor the rollout switch, limit switch, pressure switch, gas valve output and flame sense. During a Call
for Heat, the control makes sure the limit switch is closed and the pressure switch contact is open before turning on the Inducer blower, which will be energized
for 15-seconds in a pre-purge mode. Following the pre-purge period, the pressure switch contact is closed and power is applied to the hot surface ignitor (there is
a 7-second warm-up period). The gas valve is energized if a flame is sensed during this 7-second trial-for-ignition period, the blower motor will turn on following a
30-second delay. When the call for heat ends, the control will turn off the gas valve, the inducer blower will turn off after a 15-second post-purge period, and the heat
blower will turn off after the jumper-selectable period of time (if jumper is missing, default Heat Blower Off delay is 120 seconds). During a Call for Cool, the control
will energize the cool blower after a 5-second delay. When the call for cool ends, the control will turn the cool blower off after a 45-second delay.
Twinning:
The ICM286 is Twinning compatible with another ICM286 control board only. By connecting the designated “TWIN” screw terminals and the 24 VAC common together,
the controls are designed to turn on/off the blower simultaneously and at the same speed. (NOTE: An external AC relay, whose coil is connected between R & W
of the primary furnace and whose normally open contacts connect R & W of the secondary furnace, must be provided to cause both furnaces to heat). A common
ground between the two furnaces is also required.
