schedules.
User Settings:

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.
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.
AC 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 EFFICIENCY -- 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.
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 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. HIGH will only
run the high stage of furnace heat. FURNACE will allow the
furnace algorithm to control staging.
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.
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.

High Stage Timer
Minimum amount of time low stage must operate before high stage
is activated. Ten to 60 minutes. 10 = default
A demand of 5_F / 3_C or more will override the staging timer.
Off Delay
S 90 seconds
S 120 seconds (default)
S 150 seconds
S 180 seconds
Amount of time the blower will continue to run after heating has
shut off.
