Controls and Operation
www.DaikinApplied.com 77 IM 971-3 • MAVERICK I
9. After a fixed 45 seconds indoor blower delay on, the
control energizes the indoor blower.
10. After a fixed 120 seconds second stage warm-up period,
control checks the thermostat input. If W1 and W2 is
present control enters normal operating loop where all
inputs are continuously checked.
First Stage and Second Stage Removed
Simultaneously:
1. Upon a loss of W1 and W2 the gas valve is de-
energized.
2. Upon a loss of flame, each inducer will complete a five
second postpurge and the indoor blower will complete a
90 second delay OFF.
3. Control in the stand by mode with solid red LED.
The integrated control is a four-ignition system.
After a total of four cycles without sensing main burner flame,
the system goes into a 100% lockout mode. After one hour, the
ignition control repeats the prepurge and ignition cycles for 4
tries and then go into 100% lockout mode again. It continues
this sequence of cycles and lockout each hour until ignition is
successful or power is interrupted. During the lockout mode,
neither the ignitor or gas valve will be energized until the
system is reset by turning the thermostat to the “OFF” position
or interrupting the electrical power to the unit for 3 seconds or
longer. The induced draft blower and main burner will shut OFF
when the thermostat is satisfied.
The circulating air blower will start and run on the heating
speed if the thermostat fan switch is in the “ON” position. The
integrated furnace control is equipped with diagnostic LED.
The LED is lit continuously when there is power to the control,
with or without a call for heat. If the LED is not lit, there is
either no power to the control or there is an internal component
failure within the control, and the control should be replaced.
If the control detects the following failures, the LED will flash
on for approximately 1/4 second, then OFF for 3/4 second for
designated failure detections.
1. Flash: Failed to detect flame within the four tries for
ignition.
2. Flash: Pressure switch or induced draft blower problem
detected.
3. Flash: High limit or auxiliary limit open.
4. Flash: Flame sensed and gas valve not energized or
flame sensed with no “W” signal.
5. Flash: Over-temperature switch open.
Operating Instructions
DANGER
Never test for gas leaks with an open flame. It can cause an explosion or fire
resulting in property damage, personal injury or death. Use a commercially
available soap solution made specifically for the detection of leaks to check
all connections as specified in the Mechanical Installation section of these
instructions.
DANGER
The spark ignitor and ignition leading from the ignition control are high
voltage. Keep hands or tools away to prevent electrical shock. Shut off
electrical power before servicing any of the controls. Failure to adhere to
this warning can result in personal injury or death.
DANGER
Should overheating occur or the gas supply fail to shut off, shut off the
manual gas valve to the unit before shutting off the electrical supply. Failure
to do so can result in an explosion or fire causing property damage, severe
personal injury or death!
This unit is equipped with integrated furnace control. This
device lights the main burners each time the room thermostat
(closes) calls for heat. See operating instructions on the back
of the furnace/controls access panel.
To Start Furnace
1. Set the thermostat to its lowest setting.
2. Turn OFF all electric power to the unit.
3. This unit does not have a pilot. It is equipped with an
ignition device which automatically lights the burner. Do
not try to light the burner by hand.
4. Remove control door.
5. Move control knob to the “OFF” position. Turn the knob
by hand only, do not use any kind of tool.
6. Wait five minutes to clear out any gas. Then smell for
gas, including near the floor. If you smell gas, STOP!
Follow B in the safety information on the Operating
Instructions located on the back of the controls/access
panel. If you don’t smell gas, go to the next step.
7. Move the gas control knob from “OFF” position to “ON”
position. Operate this unit with the gas control knob in
the “ON” position only. Do not use the gas control knob
as a means for throttling the burner input rate.
8. Replace the control door.
9. Turn ON all electric power to the unit.
10. Set the thermostat to the desired setting.
11. If the unit will not operate, follow the instructions below
on how to shut down the furnace.
The initial start-up on a new installation may require the control
system to be energized for some time until air has bled through
the system and fuel gas is available at the burners.
