single stage thermostat. Turn ON when using
Ewo-stage thermostat to allow Low Heat operation
Nhen R to W/Wf closes and High Heat operation
Nhen R to W/W1 and W2 close.
I'urn ON to increase Low Heat airflow by 18
3ercent. This compensates for increased return ail
Eemperature caused with bypass humidifier. This
€lso increases the low heat inducer speed 15
3ercent.
I'urn ON to decrease low heat airflow by 7 percent.
end high heat airflow 10 percent for maximum
comfort.
I'urn ON for 400 CFM per ton, Turn OFF for 350
_FM per ton. See also SW4.
I'urn ON to initiate Component Self Test for
:roubleshooting assistance when R thermostat
ead is disconnected. Turn OFF when Self Test is
,'ompleted.
