difference. When the correct deadband is set, touchSAVE.
SDeadband: Adjustable from 0 to 6_F(0to2_C)
dDefault = 2_F
6.3.1.3. Offsets

6.3.2.1. Fan Coil Airflow
This option allows the installer to select the appropriate air flow based on the needs
of the installation. TheQUIETairflow means the 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
become an issue at low airflows. TheCOMFORTairflow means airflow is varied
depending on humidity and temperature demand settings. This selection enables the
full dehumidify and comfort capabilities of the system. TheEFF325airflow is a
fixed airflow used to achieve specified ratings – no dehumidification airflow

reduction is performed. This is nominally 325 CFM/ton, but will vary if a 2 --stage
outdoor unit is used. TheEFF350airflow is a fixed airflow used to achieve
specified ratings – no dehumidification airflow reduction is performed. This is
nominally 350 CFM/ton, but will vary if a 2 --stage outdoor unit is used. TheMAX
airflow is a fixed 400 CFM/ton. No dehumidification airflow reduction is
performed.
The dehumidify airflow, when set toNORMAL,isallowedtoadjusttoaminimum
to satisfy the dehumidification call. When set toHIGH, the minimum airflow
during the dehumidify mode is increased to reduce duct and register sweating. Also
the airflow increases minimum airflow during normal cooling operation to help
reduce duct sweating.
After the selections are made, touchSAVE.
SCooling Airflow:Quiet, Comfort, EFF325, EFF350, or Max
dDefault = Comfort
SDehumidify Airflow:Normal or High
dDefault = Normal
6.3.2.2. Fan Coil Dehumidification
The Dehum Drain Time option turns off the continuous fan at the end of cooling for
five minutes in order to drain the indoor coil of water. The fan will only be turned
off if a dehumidify demand existed at the start of or during the cooling cycle.
The Electric Reheat option enables the electric heat to be used while
cool--to --dehumidify is running. This will allow the cool--to --dehumidify function to
run longer, greatly improving humidity control in cooling mode. Accumulated
electrical energy used while reheating (in kilowatt--hours) is shown on the Fan Coil
Run Hours screen and can be reset there. This option is only available with fan coil
systems.
After the selections are made, touchSAVE.
SDehum Drain Time:Adjustable from 5 to 60 minutes or OFF

dDefault = 15 minutes
SElectric Reheat:Ye s o r N o
dDefault = No
6.3.2.3. Fan Coil G--Terminal
This setup option selects desired operation when the R--G circuit changes state on
the fan coil control board depending on setup.
Under the function option,FA Nturns on fan to selected fan speed when G terminal
is energized.SHUTDOWNshuts off fan and equipment when initiated. After the
selections are made, touchSAVE.
SFunction:Disabled, Fan or Shutdown
dDefault = Disabled
SFan Speed:Low, Med, or High
dDefault = Low
SShutdown:

6.3.3. Furnace
First touchSETUP, then touchFURNACEto set up the parameters for the furnace
unit.

A12189
6.3.3.1. Furnace Airflow
Selects the airflow of the furnace when heating.EFFICIENCYis the airflow used
to meet specified ratings,COMFORTis a decreased airflow used to increase the
output air temperature and provide increased comfort.
For the Low heat rise option, set to ON if the system contains a bypass humidifier.
The ON setting will increase the furnace low heat airflow.
After the selections are made, touchSAVE.
SFurnace Air Flow:Comfort or Efficiency
dDefault = Comfort
SLow Heat Rise:On or Off
dDefault = Off
6.3.3.2. AC/HP Air Flow
This option elects the airflow of the furnace when cooling, heat pump heating, and
dehumidification.
TheQUIETairflow means the 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 become an issue at low 
						

							29
airflows. TheCOMFORTairflow means airflow is varied depending on humidity
and temperature demand settings. This selection enables the full dehumidify and
comfort capabilities of the system. TheEFF325airflow is a fixed airflow used to
achieve specified ratings – no dehumidification airflow reduction is performed.
This is nominally 325 CFM/ton, but will vary if a 2 --stage outdoor unit is used. The
EFF350airflow is a fixed airflow used to achieve specified ratings – no
dehumidification airflow reduction is performed. This is nominally 350 CFM/ton,
but will vary if a 2 --stage outdoor unit is used. TheMAXairflow is a fixed 400
CFM/ton. No dehumidification airflow reduction is performed.
The dehumidify airflow, when set toNORMAL, the airflow is allowed to adjust to
a minimum to satisfy the dehumidification call. When set toHIGH, the minimum
airflow during the dehumidify mode is increased to reduce duct and register
sweating. Also the airflow increases minimum airflow during normal cooling
operation to help reduce duct sweating.
After the selections are made, touchSAVE.
SCool:Quiet, Comfort, EFF325, EFF350, or Max
dDefault = Comfort
SHP Heat:Comfort or EFF350
dDefault = Comfort
SDehumidify:Normal or High
dDefault = Normal
6.3.3.3. Furnace Staging
This option controls the staging of the furnace and selects the minimum amount of
time low stage must operate before high stage is activated.SYSTEMsetting will
allow the InfinityrZone Control to determine furnace staging.LOWwill only run
the low stage of furnace heat.LOW-- MEDwill run the low and medium stages (2
stages of heat).MEDwill only run the medium stage of heat.MED-- HIGHwill run

the medium and high stages (2 stages of heat).HIGHwill only run the high stage
of furnace heat.
NOTE: Two --stage furnace hasLOWandHIGHselections only.

dDefault = System
SHigh Stage Timer:Selectable from 10 to 60 minutes
dDefault = 10 minutes
6.3.3.4. Furnace Airflow Limits (modulating furnace only)
The following settings allow the installer to restrict the furnace within certain
minimum and maximum airflows. These airflows are converted to capacities. The
Min and Max limits are determined by the equipment size. These settings are not
the same as the zoning airflow limits.
SMin. modulating limits:Minimum CFM to run a modulating furnace. This will
increase the minimum operating capacity of the furnace.
dDefault value is the furnace air flow for the lowest heat capacity.
SMax. modulating limits:Maximum CFM to run a modulating furnace. This
will increase the maximum operating capacity of the furnace.
dDefault value is the furnace air flow for the highest heat capacity
6.3.3.5. Furnace Off Delay
This option denotes the amount of time the blower will continue to run after heating
has shut off. After the selection is made, touchSAVE.
