a.
No. Verify all associated ductwork is installed as designed, and there
are no obstructions. Continue.
b.
Yes. Continue.
4.
Does the fan RPM match that listed on the Spec. Sheet?

No. Correct to increased fan speed and continue.
b.
Yes. Continue.
5.
Are the airflow switches’ sensing tubes obstructed?

ALARM CODE:
Clogged Filter Switch
PROBLEM:
The filter air pressure switch has closed between the appropriate
terminals on the unit’s terminal strip located in the unit’s main control panel indicating a
clogged filter. See the Typical Wiring Schematic, Multiplexed Input, and Clogged Filter
sections of this manual for more information.
This alarm will automatically clear about 5
seconds after the alarm is corrected.
SOLUTION: If clogged filter switch is closing.
1.
Are the filters dirty?
a.
Yes. Install clean filters and continue.
b.
No. Continue.
2.
Are the airflow switch sensing tubes obstructed?
a.
Yes. Clear and continue.
b.
No. Continue.
3.
Is the airflow switch setpoint properly adjusted?
a.
No. Adjust setpoint.
b.
Yes. Continue.
4.
Are the wires connected to the air pressure switch’s normally open contact?
a.
No. Rewire switch and continue.
b.
Yes. Continue.
5.
Is the air pressure switch’s normally open contact open?
a.
No. Disconnect the sensing tubes and recheck. Replace the switch if
contacts do not open.
b.
Yes. Continue.
6.
Find the clogged filter switch on the electrical schematic and identify the
control panel terminals to which it is connected. Disconnect the wire from
these terminals. Does this clear the alarm?
a.
Yes. There is short in the wiring between the terminal strip and the
switch. Determine cause and rectify.
b.
No. Continue.
7.
Unplug the connector from the controller that is connected to the multiplexed
input. Does this clear the alarm?
a.
Yes. There is short in the wiring of the multiplexed resistors.
Determine cause and rectify.
b.
No. There is an internal short in the controller. Replace the controller.
