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.

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 Evolution 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. 23. 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. 24.

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

Furnace Airflow (Capacity) Limiting
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.
Min CFM (only appears with modulating furnaces)
Minimum CFM to run a modulating furnace. This will increase
the minimum operating capacity of the furnace. Default value is
the furnace air flow for the lowest heat capacity.
Maximum CFM (only appears with modulating furnaces)
Maximum CFM to run a modulating furnace. This will reduce the
operating capacity of the furnace. Default value is the furnace air
flow for the highest heat capacity.
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.
Dehum Drain
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. Default is enabled.
