Figure 7-2_Parameters Min-Max Adjustment Screen
Once adjustments to the parameters are complete, the values
can be sent by pressing the Download button in the top
section of the screen (FIG. 7-2). This will transfer the
new parameters into the SMART SYSTEM. While the
programming is taking place the appliance control will force
a Post Purge Cycle through the combustion system as a reset
function. If a call for heat was enabled, programming will
force the system to Post Purge and then automatically restart
the Ignition Cycle.
Changeable parameters
For the tables of adjustable parameters, each value adjustment
will display a “Minimum” and “Maximum” value for the
input of this field and will not allow entries beyond this range.
For descriptions of each of the adjustable parameters, please
reference the appliance’s Service Manual.
Storing parameters
Once you have customized the parameters for a particular
heater, the new settings can be stored on your PC. This will
allow you to restore these settings should you have to replace
the SMART SYSTEM control, or allow you to load these
settings into another heater at a later date.
The settings are stored as a data file. To save a file, click
the Save button at the top of the screen (FIG. 7-2) to select
a SAVE AS location and File Name for the parameter file
(.param). Click Save to store the file in a desired location.
Loading stored parameters from the PC
To retrieve a set of previously stored parameters, click on
the Load button at the top of the screen (FIG. 7-2). Once
the intended parameter file (.param) is selected, click Open
to load this file into the PC software. The file can now be
modified and/or loaded into new controls.
Restoring defaults
This program has the capability of restoring factory defaults.
To restore defaults, click on the Restore Defaults button
(FIG. 7-2). The SMART SYSTEM 938 PC program will then
communicate with the control and update the control with
the appropriate file. Please note that this process will change
all the custom boiler settings to their factory defaults.
