Defrost Fan Delay
Turns on the outdoor unit fan at the end of a defrost cycle for
approximately 12 seconds. This helps to reduce any nuisance
refrigerant noise caused by the switching reversing valve. This
setup is only available on communicating heat pumps
Brownout Disable
Turns off the high voltage brownout detection function in the
outdoor unit control.
Lo Air Multiplier
Adjusts the low airflow speed on non- -communicating two- -stage
units. Choose 0.65 for units with a Bristol compressor, choose 0.80
(default) for units with a Copeland scroll compressor.

Fig. 27 - - Hybrid Heat Setup
FURNACE LOCKOUT - - Temperature above which the furnace
will not operate, except for defrost.
S Default = NONE
S Available settings = NONE thru >55_F (13_C)
HEAT PUMP LOCKOUT - - Temperature below which the heat
pump will not operate.
S Default = NONE
S Available settings = NONE thru <55_F (13_C)
DEFROST W/FURNACE - - Choose whether furnace operates
during defrost cycle
S Default = YES
S Available settings = YES / NO
HP TO FURNACE STAGING TIME - - Adjust the minimum
amount of time high stage heat pump will run before furnace will
be allowed to run.
S Default = 15 MIN
S Available settings = 15- -60 minutes
Setup - - Zoning
Disable Zoning:
S NO (default)
S YES
If YES is selected, zoning is disabled and all dampers open. The
system will run un- -zoned using the Zone 1 sensor.
Zone Offsets:
S Zone Temperature Offsets (default = 0) Range - -5_F to +5_F
(- -3_C to +3_C)
This option allows actual temperature offset for each zone,
allowing calibration (or deliberate miscalibration) of each sensor.
Humidifier interval is time only, not actual humidifier run time.
Airflow Limits:
Since bypass damper is prohibited in this system, this setting is
used to select the maximum allowable noise/airflow relationship
into each zone based on air noise and comfort requirements. For
setup guidelines, see Airflow Limits Checkout in the next section.
S Low - - 100% of maximum assessed airflow
S Med Low - - 138% of maximum assessed airflow
> 30 F
< 15 F

15 MIN
A07030
S Medium - - 176% of maximum assessed airflow
S Med High - - 214% of maximum assessed airflow
S High - - 250% of maximum assessed airflow
S No Limit - - equipment does not stage down
CFM associated for each limit is shown on the screen. Compare
this value with the equipment's low stage CFM value to ensure that
equipment will run for each zone. Assessed airflow is determined
as described in DUCT ASSESSMENT.
Duct Assessment Time
1 p.m. (default), adjustable in 1 hour increments from 1 p.m. to 12
a.m. (24 hours). Select which hour of the day the duct assessment
will be performed.

HOT WATER LOCKOUT - - Outside temperature above which the
hot water will not operate except for defrost (if selected).
S Available settings - - NO, 5 to 55_F (- -15 to 13_C) in 1_
increments
HEAT PUMP LOCKOUT - - Outside temperature below which the
heat pump will not operate, 1_ resolution.
S Appears only with a heat pump outdoor unit.
S Available settings - - NO, 5 to 55_F (- -15 to 13_C) in 1_
increments
DEFROST W/WATER:
S Available settings: YES / NO (Default = YES)
S Appears only if heat pump is available. If no, hot water will not
run during a defrost.
AIRFLOW - - Selects desired airflow during Hydronic Heating
S Available range from OFF, 500 CFM(minimum) to 400
CFM/ton cooling maximum in 50 CFM increments.
S Default is the cooling airflow. (350 CFM/ton)
S OFF selection does not turn off airflow if heat pump is
defrosting.
BLOWER ON DELAY - - Time after hot water is requested that the
blower will turn on.
S Available settings - - 0 to 240 seconds in 30 second increments
S Default is 30
S Does not appear if a heat pump is present since heat pump and
hot water run simultaneously.
BLOWER OFF DELAY- - Time after hot water request terminates
before the blower will turn off.
S Available settings - - 0 to 240 seconds in 30 second increments
S Default is 0
Setup - - Accessories
Filter Type:
S Air Filter (i.e. TrueSenset)
S Electronic Air Cleaner
S Air Purifier (i.e. TrueSenset)
CLEAN INTERVAL: Never, 1 to 18 months. (Default = 90)
Enables a timer for the filter notification.
