Integrated Control DIP Switch Settings A96DF2E units
are equipped with a two-stage integrated control. This
control manages ignition timing, heating mode fan off de-
lays and indoor blower speeds based on selections made
using the control dip switches and jumpers. The control
includes an internal watchguard feature which automati-
cally resets the ignition control when it has been locked
out. After one hour of continuous thermostat demand for
heat, the watchguard will break and remake thermostat
demand to the furnace and automatically reset the control
to relight the furnace.
Heating Operation DIP Switch Settings
Switch 1 -- Thermostat Selection -- This unit may be
used with either a single-stage or two-stage thermostat.
The thermostat selection is made using a DIP switch
which must be properly positioned for the particular ap-
plication. The DIP switch is factory-positioned for use with
a twostage thermostat. If a single-stage thermostat is to
be used, the DIP switch must be repositioned.
a- Select "OFF" for two-stage heating operation controlled
by a two-stage heating thermostat (factory setting);
b - Select "ON" for two-stage heating operation controlled
by a single-stage heating thermostat. This setting
provides a timed delay before second-stage heat
is initiated.
Switch 2 -- Second Stage Delay (Used with Single-
Stage Thermostat Only) -- This switch is used to de-
termine the second stage on delay when a single-stage
thermostat is being used. The switch is factory-set in the
OFF position, which provides a 7-minute delay before
secondstage heat is initiated. If the switch is toggled to
the ON position, it will provide a 12-minute delay before
secondstage heat is initiated. This switch is only activated
when the thermostat selector jumper is positioned for
SINGLEstage thermostat use.
Indoor Blower Operation DIP Switch Settings
Switches 3 and 4 -- Heating Mode Blower-Off Delay --
The blower-on delay of 30 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 3 and 4 on the integrated control. 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 be-
tween 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 temperatures. Table 12 provides the blower off
timings that will result from different switch settings.
