DEFROST: NO
The heat pump heating mode can be exercised with this menu
option. With a 2-speed heat pump, a low heat runtime and a high
heat runtime are independently selectable to exercise. A defrost
cycle is also selectable. Default time = Fixed 5 min. minimum,
range = 5 - 120 min.

unit, a low cool runtime and a high cool runtime are independently
selectable to exercise. The display will change to show the heat

DUCT ASSESSMENT
This is the same Duct Assessment that runs on first start-up.
Measures duct capacity for each zone. The Duct Assessment will
perform an airflow measurement on each zone and determine the
relative size of each zone along with damper leakage. This
assessment will require approximately 1 minute for each zone in
the system.
NOTE:
A Duct Assessment will automatically occur every 24
hours at 1:00 p.m. to check system static and calibrate dampers.
SENSOR DAMPER CHECK:
The Sensor/Damper Check allows the installer to check each zone
damper for operation, as well as insure the zone sensor corre-
sponds to that particular zone.
When first initiated, the Zone 1 damper will fully OPEN, and all
other zones will CLOSE. Using the scroll button, the installer can
select each zone and verify the damper is fully open while all other
dampers remain closed.
After proper damper operation has been verified, the installer can
now check and verify that each remote room sensor corresponds to
the proper zone damper in the same zone. Start from the top and
highlight zone 1 to open damper. Temporarily disconnect any
other zone remote room sensor (at sensor location). That zone
damper will now OPEN, while the Zone 1 damper will close.
EXAMPLE: If the Zone 2 remote room sensor is disconnected, the
Zone 2 damper will now open as indicated on the User Interface
display. The word
″
FAIL
″
will also be displayed instead of the
actual temperature for Zone 2. Reconnect Zone 2 sensor and try all
remaining sensors one at a time in the system. Smart Sensors may
also be checked, see Smart Sensor Installation Instructions for
procedure.
AIRFLOW LIMITS:
•
Low
•
Medium
•
High (default)
•
Maximum
Because there is no bypass damper, the Zone Airflow Limit check
will allow the installer to assess the airflow noise generated by the
system providing the maximum amount of airflow to each zone.
Select 9 ZONE, then select AIRFLOW LIMIT: Low, Medium,
High (default), or Maximum. When Start is pressed (right side
button), the selected zone’s damper will fully open, all others will
close, and the indoor unit will provide the maximum airflow for
that zone (as selected in Setup = ZONING, Airflow Limits). If the
airflow noise is objectionable, the installer can select a lower
airflow noise limit. If the noise is not objectionable, the installer
should leave High selected, or even Maximum.
NOTE:
Selecting a lower airflow noise limit may decrease the
homeowner’s comfort in that zone.
SERVICE MENUS
The Service Info menu will only show the equipment installed in
the system. Below is a sample using a furnace and a heat pump
(dual fuel). A sample service menu is shown in Fig. 25.
Service = FURNACE STATUS
The Status screens will show all of the current operating param-
eters of each installed piece of equipment.
HEAT STAGE:
•
OFF, LOW, HIGH
Displays stage of heat that the furnace is currently delivering.
AIRFLOW CFM:
•
(furnace model 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 furnace.
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 in return-air, will read
return-air temperature).
INDUCER RPM (90% furnaces only):
•
Inducer motor RPM value.
BLOWER RPM:
•
Blower motor RPM value.
STATIC PRESS:
•
Inches of water. Displays static pressure that the furnace is
currently experiencing.
