Use & Care Manual

OFF - Turns heating and cooling modes
off. (The blower may still circulate air in
the FAN-ON position.)
FAN-ON - Turns the blower on for
continuous operation.
FAN-AUTO - The blower cycles on and
off with cooling or heating operation.
This furnace has a negative pressure
switch that is a safety during a call for
heat. The induced draft blower must
pull a negative pressure on the heat
exchanger to close the negative
pressure switch. The induced draft
blower must maintain at least the
negative pressure switch set point for
the furnace to operate. If the induced
draft blower fails to close or maintain
the closing of the negative pressure
switch, a “no heat call” would result.
