DESCRIPT ION OF USE
Turn ON to retrieve up to 7 stored status codes for
OFF troubleshooting assistance when R thermostat lead is
disconnected.
When SW1 -2 is OFF allows two-stage operation with a single
stage thermostat. Turn ON when using two- stage thermostat to
OFF
allow Low Heat operation when R to W/W1 closes and High Heat
operation when R to W/W1 and W2 close.
Turn ON to increase Low Heat airflow by 1 8 percent. This
OFF compensates for increased return air temperature caused with
bypass humidifier.
Turn ON to decrease low heat airflow by approximately 7 percent
ON
and high heat by approximately 1 0 percent for maximum comfort
Turn ON for 400 CFM per ton, Turn OFF for 350 CFM per ton.
OFF
See also SW2.
Turn ON to initiate Component Self Test for troubleshooting
OFF assistance when R thermostat lead is disconnected. Turn OFF
when Self Test is completed.
Blower Off Delay time – adjustable 90 seconds to 1 80 seconds.
See table in Adjustments section or refer to unit wiring diagram.
Allows for selection of furnace Main (OFF) or Secondary (ON)
OFF when Twinned furnace setup is required. See kit instructions for
further directions on installation and setup.
Allows additional CFM per ton selections when used with SW 1 -5
325 CFM per ton (nominal) when SW 2-2 ON and SW 1 -5 OFF
350 CFM per ton (nominal) when SW 2-2 OFF and SW 1 -5 OFF
OFF
370 CFM per ton (nominal) when SW2-2 ON and SW 1 -5 ON
400 CFM per ton (nominal) when SW 2-2 OFF and SW 1 -5 ON
See Air Delivery Tables for model specific CFM vs. static
pressure
The AC setup switches select desired cooling or high stage
OFF cooling (two stage units) airflow. See Cooling Air Delivery Tables
for specific switch settings.
The CF setup switches select desired Continuous Fan Airflow
The CF switch position is the low cooling airflow selection for two
stage cooling units.
OFF
The CFM values are shown in the Air Delivery Tables below for
SW 2 settings. SW 2-3, 4, 5 cannot be set for airflow higher than
SW 2-6, 7, 8. See Continuous Fan Air Flow Table for specific
switch settings.
