- There are several parameters that can be adjusted for the speci fi c application. The
adjustable parameters are as follows.
- APP
a. Determine the functionality of the inputs by specifying which type of burner the control
is being used on.
b. vA-A is for VA series burners that use an intermittent pilot.
c. vA-B is for VA series burners that use an interrupted pilot.
d. noX is for Midco Low-NOx series burners.
- tLo and thi
a. Use these parameters to adjust the minimum and maximum temperature set point that
a user can set while outside of programming mode. NOTE : These parameters only
have an e ff ect on the operation of the burner when the burner is operated by a
temperature control.
- FLo and Fhi
a. Use these parameters to adjust the minimum and maximum speed that the
combustion blower can achieve (displayed as a percentage of the maximum capacity
of the blower).
b. Adjusting FLo will change the speed of the combustion air blower during ignition and
when in run mode at 2.0V DC. This e ff ectively changes the minimum fi ring rate. The
default setting is 10% of maximum fan speed.
c. Adjusting Fhi will change the speed of the combustion air blower while in run mode
with a 10.0V DC input signal. This e ff ectively changes the maximum fi ring rate of the
burner. The default setting is 100% of maximum fan speed.
- inPt
a. This parameter is used to specify which type of input is used to control the modulation
of the burner.
b. dC is for using a 2-10V DC input signal sent from an external temperature controller.
c. rE is used when one connects a discharge temperature sensor as well as an external
thermostat. The SCEBM-2 still modulates the burner based on the discharge
temperature and the temperature set point, but in this mode the temperature set point
is set from an external device.
d. tS is the setting used when one connects a discharge temperature sensor directly
to the SCEBM-2 module. The SCEBM-2 then modulates the burner based on the
discharge temperature and the temperature set point.
- ovEr
a. Enables or disables the manual override function. When enabled, the user can adjust
the combustion fan speed manually using the up and down arrows. The input signal
from the external temperature controller or the discharge temperature sensor will be
overridden.
-
Pid
a. This parameter is used to adjust how aggressively the SCEBM-2 module tracks
the discharge temperature. NOTE : This parameter only has an e ff ect on the operation
of the burner when the burner is operated by a temperature control.
- oFS
a. This parameter is used to adjust the discharge air sensor. NOTE : This
parameter only has an e ff ect on the operation of the burner when the burner is
operated by a temperature control.
- ForC
a. This parameter is used to choose whether the SCEBM-2 module displays the
temperature in degrees Fahrenheit or degrees Celsius. NOTE : This parameter only
has an e ff ect if there is a temperature discharge sensor hooked up to the SCEBM-2.
- PASS
a. This parameter enables or disables the password. If the password is enabled, one
must enter it in order to access the program menu.
- vEr
a. The installed version of the software.
