Range of operation of the indoor blower during continuous blower operation.
The range is 450 to 2150 CFM. Default is dependent on component match-up. Incremental adjustments are made in 5 CFM.
Continuous Indoor
NOTE:
All iComfort parameter default CFM values are based on Air Handler Control (AHC) DIP switch setting (non-communicating value) prior to power up. This
Blower Airflow
dip switch settings are use and calculated using CFM conversion tables. They are then rounded up to closest number on 25 CFM resolution. Any DIP switch
changes made after power up are ignore.
Cooling Indoor
The range is 0 - 30 seconds. Default is 0 seconds with an incremental adjustment of 2 seconds.
Blower Off Delay
Cooling Indoor
The range is 0 - 10 seconds. Default is 2 seconds with an incremental adjustment of 1 second.
Blower On Delay
Range of operation of the indoor blower during electric heat operation.
Electric Heating
Airflow The range is 1560 to 2150 CFM. Default is dependent on unit capacity with an incremental adjustment of 5 CFM.
Equipment Name A unique name can be assigned to this component. Name can be up to 29 characters. Name can consist of letters, numbers, special characters and spaces.
Heating Indoor Blower OFF Delay (Electric Heat only -Blower runs at continuous air CFM setting during delay timing period).
Heating Indoor
Blower Off Delay
The range is 0 - 10 seconds. Default is 10 seconds with an incremental adjustment of 1 second.
Heating Indoor
The range is 0 - 5 seconds. Default is 0 seconds with an incremental adjustment of 1 second.
Blower On Delay
High Cooling Range of operation of the indoor blower during high cooling operation.
Airflow
The range is 1560 to 2150 CFM. Default is based on cooling demand with an incremental adjustments of 25 CFM.
Range of operation of the indoor blower during high heat pump operation.
High HP Airflow Information below is example only and exact air flow range is dependent on equipment tonnage. Use your example and add adjustment increments of +/-25 CFM
Example: The range is 800 -1100 CFM. Default setting is depending on unit tonnage. Can be incrementally adjusted by 25 CFM.
HP Indoor Blower Heat Pump Indoor Blower OFF Delay (Heat Pump only - Blower runs at continuous air CFM setting during delay timing period).
Off Delay
The range is 0 - 60 seconds. Default is 45 seconds with an incremental adjustment of 5 seconds.
HP Indoor Blower
The range is 0 - 30 seconds. Default is 0 seconds with an incremental adjustment of 5 seconds.
On Delay
Range of operation of the indoor blower during low cooling operation.
Low Cooling
Airflow The range is 450.0 to 2150 CFM. Default is based on cooling demand with an incremental adjustments of 25 CFM.
Range of operation of the indoor blower during low heat pump operation.
Low HP Airflow Information below is example only and exact air flow range is dependent on equipment tonnage. Use your example and add adjustment increments of +/-25 CFM.
Example: The range is 450 - 600 CFM. Default setting is depending on unit tonnage. Can be incrementally adjusted by 25 CFM.
Reset Air Handler Any installer modifications under the air handler tab will be reset back to the factory defaults if the reset air handler option is used.
