Integrated Control DIP Switch Settings
EL296DFE units are equipped with a two-stage integrat-
ed control. This control manages ignition timing, heating
mode fan off delays and indoor blower speeds based on
selections made using the control dip switches and jump-
ers. The control includes an internal watchguard feature
which automatically 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 appli-
cation. The DIP switch is factory-positioned for use with a
two stage 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 SIN-
GLEstage thermostat use.
Indoor Blower Operation DIP Switch Settings Switch-
es 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 de-
lay to achieve a supply air temperature between 90° and
110°F at the exact moment that the blower is de-ener-
gized. 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.
