Carrier Infinity SYSTXCCUID01-V Installation Instructions Manual page 9

Reset Factory Defaults:
Program Schedule:
S Yes/No to reset back to Energy Star default Time and Temp
schedules.
User Settings:
S Yes/No to reset the user settings in the Advanced Setup to
factory default settings.
Install Settings:
S Yes/No to reset install settings in Install/Service menus to factory
default settings.
Last 10 System Events:
S Yes/No to reset last 10 events under Service Info menu.
Setup - - Furnace
Upon a first time start- -up of the Infinity Control, the furnace DIP
switch settings will be copied to the furnace setup menu. Any
changes can then be made from the Infinity Control.
Furnace Airflow:
S COMFORT (default)
S EFFICIENCY
Selects the airflow of the furnace when heating. EFFICIENCY is
the airflow used to meet specified ratings, COMFORT is a
decreased airflow used to increase the output air temperature and
provide increased comfort.
Cooling Airflow:
S COMFORT (default) - - cooling airflow is varied depending on
humidity and temperature demands settings. This selection
enables the full dehumidify and comfort capabilities of the
system. When COMFORT is not selected, the unit will not run
reduced airflows for dehumidification.
S EFF 325 - - fixed airflow used to achieve specified ratings - - no
dehumidification airflow reduction. This is nominally 325
CFM/ton, but will vary if a 2- -stage outdoor unit is used.
S EFF 350 - - fixed airflow used to achieve specified ratings - - no
dehumidification airflow reduction. This is nominally 350
CFM/ton, but will vary if a 2- -stage outdoor unit is used.
S MAXIMUM - - 400 CFM/ton. No dehumidification airflow
reduction.
S QUIET- - minimum cooling airflow that the system can safely
run (typically 300 CFM/ton). Use this setting if duct noise is a
severe problem. Note that duct sweating in high humidity
environments could be an issue.
Heat Pump Heating:
S COMFORT (default) Heat Pump airflow is varied depending on
outdoor temperature to maximize comfort.
S EFF 325 - - Fixed airflow used to achieve specified ratings . This
is nominally 325 CFM/ton, but will vary if a 2- -stage outdoor
unit is used.
S EFF 350 - - Fixed airflow used to achieve specified ratings . This
is nominally 350 CFM/ton, but will vary if a 2- -stage outdoor
unit is used.
S MAXIMUM - - 400 CFM/ton.
Heat Pump Cooling:
S COMFORT (default) - - cooling airflow is varied depending on
humidity and temperature demands settings. This selection
enables the full dehumidify and comfort capabilities of the
system. When COMFORT is not selected, the unit will not run
reduced airflows for dehumidification.
S EFF 325 - - fixed airflow used to achieve specified ratings - - no
dehumidification airflow reduction. This is nominally 325
CFM/ton, but will vary if a 2- -stage outdoor unit is used.
S EFF 350 - - fixed airflow used to achieve specified ratings - - no
dehumidification airflow reduction. This is nominally 350
CFM/ton, but will vary if a 2- -stage outdoor unit is used.
S MAXIMUM - - 400 CFM/ton. No dehumidification airflow
reduction.
S QUIET- - minimum cooling airflow that the system can safely
run (typically 300 CFM/ton). Use this setting if duct noise is a
severe problem. Note that duct sweating in high humidity
environments could be an issue.
Dehum Airflow:
S NORMAL (factory default) - - When equipment is running to
dehumidify, the airflow is allowed to adjust to a minimum to
satisfy the dehumidification call.
S HIGH - - Minimum airflow during the dehumidify mode is
increased to reduce duct and register sweating.
Low Heat Rise
S ON
S OFF (default)
Set to ON if the system contains a bypass humidifier. The ON
setting will increase the furnace low heat airflow.
Staging
S SYSTEM (default)
S LOW
S LOW- -MED
S LOW- -HIGH
S MEDIUM
S MED- -HIGH
S HIGH
S FURNACE
NOTE: Controls the staging of the furnace. More staging options
will be available if furnace is capable of more stages. SYSTEM
setting will allow the Infinity Control to determine furnace staging.
LOW will only run the low stage of furnace heat. LOW- -MED
will run the low and medium stages (2 stages of heat). MED will
only run the medium stage of heat. MED- -HIGH will run the
medium and high stages (2 stages of heat). HIGH will only run the
high stage of furnace heat.
G Terminal
This setup option selects desired operation when the R- -G circuit
changes state on the furnace control board depending on setup.
S DISABLED (Default)
S FAN - - turns on fan to selected fan speed when G terminal is
energized. See Fig. 26. This setting is used in conjunction with
fresh air supply products (e.g. fresh air/make- -up air dampers).
S FAN SPEED - - select Low, Med, High for all zones when G
terminal is energized
S SHUTDOWN - - shuts off fan and equipment when initiated.
This function is not intended for emergency fire shutdown. It
may be activated by a dry contact from an external device such
as a float switch or a relay. User Interface displays SYSTEM
MALFUNCTION on screen and registers G terminal shutdown
event in Last 10 System Events. See Fig. 27.
