NOTE: If two air cleaners are connected on the same
system, set all timers on both air cleaners to the same
settings. The comfort control will only report one air
cleaner timer and this methodology will allow the air
cleaners to remain on the same cleaning schedule.
FIELD CHARGER Power Level
The Red LED lights are used to set the power level of the
FIELD CHARGER for maximum, medium, or minimum. The
number of illuminated Red LED lights indicates the current
setting. The factory setting is for maximum.
Lower settings will reduce the slight sound emitted by the
unit with minimal loss of air cleaning efficiency, if desired.
Lower settings will also further reduce the very low ozone
produced by the Air Cleaner. The U.S. Food and Drug
Administration recommends indoor ozone concentrations
should not exceed 50 parts per billion. The Air Cleaner will
contribute only 5 parts per billion at the factory setting and
can be reduced to .3 parts per billion at the minimum
setting.
FIELD CHARGER Power Level Setting (Fig. 7)
One or more of the Red LED lights will illuminate. To
change the power level setting, press the RESET button
until the desired setting is indicated.
To save your new settings and exit the SET-UP mode, press
and hold BOTH the POWER and filter RESET buttons for a
minimum of 5 [6] seconds.

FAULT CODES
The Air Cleaner LEDs will display a fault indication, three
yellow or three Red LEDs, when a fault has been detected.
A log of the last three faults is recorded and can be
accessed by going into the SET-UP mode. The unit will
repetitively check the system to determine if the fault
persists. The fault indication will be displayed as long as the
fault condition remains.
If the fault is no longer present, the system will return to
normal operation and no longer display the fault indication.
Even if the fault has been corrected, a log of the last 3 faults
is recorded.

or the COLLECTION CELLS need to be cleaned. The Air
Cleaner control has detected ten consecutive automatic High
Voltage Shut Down (HVSD) cycles. An automatic HVSD cycle is
normally activated by the control system when an internal
electrical arc occurs.
THREE RED LEDS & THE PRE-FILTER LED FLASHING
This means service is needed. For these THREE Red LEDs to
flash on and off the control must have detected the SAME FAULT
(see Fault Code Table on page 5) THREE TIMES in a row. The
PRE-FILTER will flash during the 3 flashing Yellow LEDs or 3
flashing Red LEDs lockout mode.
FAULT CODES RETRIEVAL
To retrieve the last three faults that the Air Cleaner Control
has detected, enter the SET-UP mode of operation.
Press and hold the POWER
for a minimum of five seconds. When the control enters the
SET-UP mode of operation some of the Green, Yellow and
Red LEDs will be on. The color and number of LEDs that are
on indicates how the control is presently programmed. (See
SET-UP CHARTS on previous page). To enter the Fault
Codes section press and hold the RESET Button for ten
seconds. After ten seconds the main LED display will go out
for one second and then some of the LEDs may begin to flash
on and off. If no fault has been detected then only the first
Green LED will be flashing on and off. The flashing Green
LED or LEDs identifies the fault number being reported out.
One Green Led flashing on and off means the last fault
detected is being reported out, two Green LEDs flashing
means the second fault detected is being reported out and
three Green LEDs flashing means the last fault stored in the
control memory is being reported out. The last three faults
detected will be stored in the control's memory and the last
fault detected will be the first fault reported out.
You are now in the Fault Log report section and the last fault
detected is now being reported out. To step through the faults,
press the POWER
button again to get the second fault and
again pressing the POWER
fault stored in the control's memory. Push the POWER
button again and the control will display the last fault detected.
To exit the SET-UP mode, press and hold both the POWER
and Filter RESET buttons for a minimum of 5 seconds.
FAULT CODES
When a fault is being reported out check the position number
of any of the Yellow and Red LEDs flashing on and off.
Compare this combination of flashing LEDs position numbers
to the Fault Code chart to see which fault has been detected.
The number one Yellow LED will always be out in the Fault
Code report section.
Dual Air Cleaner Faults and Filter Reset:
When dual air cleaners are installed as part of a
communicating system, each whole house air cleaner will
retain its own faults.
However, in a communicating system with dual air cleaners,
the 900 series comfort control will only recognize the filter
timers for one air cleaner. Both the Pre-Filter and Collection
Cell timers for one air cleaner can be reset at the comfort
control.
