SERVICE INFORMATION SCREENS
Typically, when any of these service tests is being performed,
the serviceperson should check operation visually, with special
instrumentation (if available), and view operational data on the
SERVICE INFORMATION screens. Refer to iQ Drive training
information for how to view these screens.

Most of the items on the SERVICE INFORMATION menu are
self-explanatory by title. Some key features are the following
(by item name):
FAULT STATUS – The top entry is ACTIVE FAULT. This
should show NO FAULT unless the last fault detected has
not cleared after its 5 minute lockout period, or the fault
condition still exists. The remainder of the screen shows a
history of previous faults or conditions detected, with military
time and date stamps for each. (Having the correct time and
date confi gured is important in making this list useful.) Use
the key to view the remainder of the last (most recent) 10
faults logged. Generally, fault logging is not functional during
Service Tests.

COMPRESSOR STATUS – This screen should confi rm the
confi gured size as MODEL NUMBER (20 = 2 tons, 30 = 3
tons, etc.) With correct confi guration only 20, 30, or 40 should
appear here. LOW PRESSURE SW shows the state of the
low pressure switch. Any COMPR ERROR CODE number
(normally 0) will be logged in the FAULT STATUS screen in
more easily understood wording. The displayed information
is read from the outdoor unit.
OUTDOOR FAN STATUS – Any FAN ERROR CODE number
(normally 0) will be logged in the FAULT STATUS screen in
more easily understood wording.
INDOOR FAN STATUS – The contents of this screen varies
depending on which type of blower motor is in the equipment
and whether or not iQ Zone is in use. Much of the information
is not useful to the installer.
TEMPERATURE STATUS – This screen lists all temperatures
measured by the iQ system. TEMP AT TSTAT is the local
temperature used for control (when zoning is not enabled),
and it displays one decimal place without showing the decimal
point (e.g., 704 = 70.4°). In iQ Zone systems, a supply duct
temperature sensor is required, and its reading is displayed
here.
CLEAR FAULT HISTORY – It is recommended that any faults
that appeared during and as a consequence of installation be
cleared out before leaving.
CALIBRATION DATA – A Panasonic blower can be recalibrated
any time from this screen by pressing the key. This may be
done if a signifi cant change has been made to blower discharge
ducting or damper usage. This screen is not normally useful to
an installer. Data is not displayed for type “B” blower motors.
COMMUNICATION DATA – This important screen indicates the
status of communication with all elements on the iQ bus. All
should show OK. If not, investigate and resolve communication
wiring issues. In iQ Zone systems only, the entry ZONE BOARD
will be displayed, representing the main Airzone control board.
