LOCKOUT TIMER:
•
Seconds
If a lockout timer is active, this will show the current time value.
See furnace manual for details on lockout timers.
Service = FAN COIL STATUS
ELECTRIC HEAT:
•
OFF, LOW, MED, HIGH
Displays stages of electric heat that the fan coil is currently
delivering.
AIRFLOW CFM:
•
(fan coil model number dependent)
Cubic Feet per Minute of air the blower is currently delivering.
LEAVING AIR TEMP:
This sensor is NOT required. However, if LAT sensor is
connected to the Damper Control Module, the sensor will read
leaving air temperature of the fan coil.
COIL TEMP:
This sensor is NOT required. However, if HPT sensor is
connected to the Damper Control Module, the sensor will read
temperature at that location (i.e. if placed down stream from
evaporator coil, and before electric heat, will read coil leaving air
temperature).
BLOWER RPM:
•
Blower motor RPM value
STATIC PRESS:
•
Inches of water
Displays static pressure that the fan coil is currently experiencing.
Service = HEAT PUMP / AC STATUS
STAGE: (HEAT / COOL):
•
OFF, LOW, HIGH
Displays stage of heating or cooling that the Heat Pump/AC is
delivering.
DEFROST:
•
NO, YES
Displays status of defrost mode if heat pump.
AIRFLOW CFM:
•
Indoor unit CFM measurement.
LEAVING AIR TEMP:
This sensor is NOT required. However, if LAT sensor is
connected to the Damper Control Module, sensor will read leaving
air temperature of the indoor unit.
COIL TEMP (outdoor unit):
•
Degrees F.
Temperature of the outdoor unit coil (only available on 2-speed
communicating outdoor units).
BLOWER RPM:
•
RPM feedback from indoor motor.
STATIC PRESS:
•
Static pressure of indoor unit.
Service = ZONING STATUS
ZONE STATUS:
This screen will show each zone in the system with the corre-
sponding damper position (POS), and CFM being delivered to
each zone. Damper position range from 0 to 15 (0=closed,
15=open).
Service = LAST 10 SYSTEM FAULTS
This screen will show last 10 faults that occurred throughout the
system. Each fault has the time and date incident recorded. Service
technician should enter current date in
″
TODAY’S DATE
″
menu
section BEFORE checking and logging the last 10 system faults.
Each fault has a two-letter acronym preceding the fault name to
identify which piece of equipment generated the fault. This fault
history can be cleared under Thermostat Setup, Reset Factory
Defaults.
•
HP = heat pump
•
AC = air conditioner
•
FN = furnace
•
FC = fan coil
•
ZO = zoning
Service = RUN / FAULT HISTORY
The indoor unit and outdoor unit (if communicating) have the
following histories:
NOTE:
For Critical Fault Screens, see Troubleshooting section in
this document.
Resettable Faults:
•
Fault counters for each piece of equipment that can be reset.
Cycle Counters:
•
Number of heat/cool/power cycles the unit has performed.
Run Times:
•
Lifetime hours of operation in heating, cooling, and how long
the unit has been powered.
Service = TODAY’S DATE
•
This menu item allows the installer to enter the current date. It
is used for time/date stamping of system faults. This should be
entered every time prior to viewing

Service = MODEL / SERIAL NUMBERS
•
This menu item allows the installer to view the model number
and serial number (if available) of all communicating pieces of
equipment in the system.

This menu item allows the installer to enter a name and phone
number that the homeowner can call for future service of the
system. This name and phone number will appear to the home-
owner whenever a service reminder pop-up message is displayed
