Locking furnace into 
"low fire" may help 
prevent over 
conditioning in the 
heating mode. This will 
allow the furnace to 
stage between low and 
high fire. Before using 
this feature read 
furnace Installation 
Instructions for two-
stage operation. 
Connect "W2" from the 
Comfort Zone Center 
to "W2" on the furnace 
control board.
