Notes
SW1-4 FAN SPEED SELECT – This
dipswitch is used to select the continu-
ous fan speed when the furnace is con-
figured with a non-communicating ther-
mostat.
“OFF”
½ HP MOTORS = Approx. 600 CFM
1 HP MOTORS = Approx. 1000 CFM
“ON”
½ HP MOTORS = Approx. 1200 CFM
1 HP MOTORS = Approx. 2000 CFM
SW1-3 HEAT RISE ADJUST – This dip-
switch is used to select desired temper-
ature rise in the heating mode. The
heat rise wi
ll always be closer to the tar-
get if the supply air sensor is properly
installed (see sub-section in this section
titled “SA SENSOR” below).
“OFF” will yield the maximum heat rise.
(Target heat rise is 65°F but this value
may vary slightly between low and high
fire. Temp. rise will always be closer to
the target if the “SA SENSOR” is prop-
erly installed.)
“ON” will increase the airflow to yield the
minimum heat rise. (Target heat rise is
55°F but this value may vary slightly
between low and high fire. Temp. rise
will always be closer to the target if the
“SA SENSOR” is properly installed.)
SW1-5 AND SW1-6 – COOLING
AND HEAT-PUMP AIRFLOW
ADJUSTMENT – These dipswitches
are used to adjust the cooling and
heat-pump airflow for non-communi-
cating systems slightly based on the
user’s preference.
SW1-5 = “OFF”, SW1-6
= “OFF” –
No adjustment.
SW1-5 = “ON”, SW1-6 = “OFF” –
+10% adjustment.
SW1-5 = “OFF”, SW1-6 = “ON” – -
