Dip Switch Settings
Switches 1 and 2 −− Blower Off Delay −− The blower−on
delay of 45 seconds is not adjustable. The blower−off delay
(time that the blower operates after the heating demand
has been satisfied) can be adjusted by moving switches 1
and 2 on the integrated control board. The unit is shipped
from the factory with a blower−off delay of 90 seconds. The
blower off delay affects comfort and is adjustable to satisfy
individual applications. Adjust the blower off delay to
achieve a supply air temperature between 90° and 110°F at
the exact moment that the blower is de−energized. Longer
off delay settings provide lower supply air temperatures;
shorter settings provide higher supply air temperatu-
res.The table below provides the blower off timings that will
result from different switch settings.

Switch 3 −− Second Stage Delay (Used with Single−
Stage Thermostat Only) −− This switch is used to deter-
mine the second stage on delay when a single−stage ther-
mostat is being used. The switch is factory−set in the ON
position, which provides a 10−minute delay before second−
stage heat is initiated. If the switch is toggled to the OFF
position, it will provide a 15−minute delay before second−
stage heat is initiated. This switch is only activated when
the thermostat selector jumper is positioned for SINGLE−
stage thermostat use.
Switch 4 −− Not used in G60UHV application.
Switches 5 and 6 −− Cooling Mode Blower Speed −−
Switches 5 and 6 are used to select cooling blower motor
speed. The unit is shipped from the factory with the dip
switches positioned for high speed (4) indoor blower motor
operation during the cooling mode. The table below pro-
vides the cooling mode blower speeds that will result from
different switch settings. Refer to blower data tables at the
front of this manual for corresponding cfm values.

Switches 7 and 8 −− Blower Speed Adjustment −−
Switches 7 and 8 are used to select blower speed adjust-
ment settings. The unit is shipped from the factory with the
dip switches positioned for NORMAL (no) adjustment. The
dip switches may be positioned to adjust the blower speed
by +10% or −10% to better suit the application. The table
below provides blower speed adjustments that will result
from different switch settings. Refer to blower data tables at
the front of this manual for corresponding cfm values.

Switches 9 and 10 −− Cooling Mode Blower Speed
Ramping −− Switches 9 and 10 are used to select cooling
mode blower speed ramping options. Blower speed ramp-
ing may be used to enhance dehumidification perfor-
mance. The switches are factory set at option A which has
the greatest effect on blower motor performance. The table
below provides the cooling mode blower speed ramping
options that will result from different switch settings. The
cooling mode blower speed ramping options are detailed
on Page 14. See unit nameplate for manufacturing date.
