NOTE: 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.
See Furnace Installation Instructions For Details Involving
Set-Up Switch Configuration and Two-Stage Furnace Operation.
