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 system events under Service Info menu.
Setup -- Furnace
Upon a first time start--up of the Infinity Zone Control, the furnace
DIP switch settings will be copied to the furnace setup menu. Any
changes can then be made from the Infinity Zone 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.
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 -- 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.
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. Also increases
minimum airflow during normal cooling operation to reduce
duct 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
MED
S
MED--HIGH
S
HIGH
NOTE
: Two--stage furnace has LOW and HIGH selections only.
Controls the staging of the furnace.
SYSTEM
setting will allow
the Infinity Zone 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. 28. This setting is used in conjunction with
fresh air supply products (e.g. fresh air/make--up air dampers).
R
G
FE Fan Coil or
Variable Speed Furnace
A07114
Fig. 28 -- G Input Wiring for Blower Operation
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 selects whether the contact is
NC -- normally closed (default) or NO -- normally open. User
Interface displays SYSTEM MALFUNCTION on screen and
registers G terminal shutdown event in Last 10 System Events.
See Fig. 29.
