DISPLAY FEATURES (Fig. 14)
The air cleaner display can be used for several functions:
•
Provide the homeowner the operating status of the air
cleaner, including an indication the PRE-FILTER or
COLLECTION CELLS need cleaning.
•
The installer accesses the Set-Up Mode to change the
time to clean settings for the PRE-FILTER and
COLLECTION CELLS as well as change the power level
setting.
•
The unit will display fault codes for the homeowner
indicating there is a problem with the air cleaner and
various fault codes for the service technician to assist in
troubleshooting the problem.
AIR CLEANER OPERATION
Turn the air cleaner on by pushing the POWER button. The
backlit POWER and Filter RESET buttons will illuminate
along with the first green LED (G1) indicating 24 volt power
is present to the air cleaner.
When the indoor fan is operating the first LED (G1) will
slowly flash. This indicates the FIELD CHARGER and
COLLECTION CELLS have power and the unit is operating
normally. There is a slight time delay between the indoor fan
starting and LED (G1) flashing.
In normal operation, the air cleaner makes a slight sound as
the air passes through it and is cleaned. In some
applications, you may notice this sound coming from the
return air vent(s). If desired, this sound level can be
reduced with minimal impact on air cleaning efficiency by
reducing the power setting of the FIELD CHARGER in the
Set-Up Mode, see page 8.
NOTE: There is a 10 minute delay after the indoor fan
operates, before the air cleaner starts to operate, each
time the power to the air cleaner is turned off/on. This can
be bypassed by going into and then out of the Set-Up
mode
SET-UP MODE
A combination of RED, YELLOW, and GREEN LED's are
used to indicate the following settings.
•
The three GREEN LED's are used to indicate PRE-FILTER
cleaning interval. This is measured in actual run time of the
indoor fan. The default setting is 2 months.
Pub. No. 18-HE56D1-3
Field Upgrade Guide
•
The four YELLOW LED's indicate the collection cell
cleaning interval. This is measured in actual run time of the
indoor fan. The default setting is 6 months.
•
The three RED LED's indicate the power level setting. The

SET-UP MODE OF OPERATION
To enter the Set-Up Mode press and hold both the POWER
and RESET buttons for a minimum of 5 seconds. The current
settings are then displayed. See Fig. 15 If this is the desired
setting or at any time you want to exit the Set-Up mode,
press and hold BOTH the POWER and RESET buttons for a
minimum of 5 seconds to exit.
