Displays the default DC drive voltage provided to the blower
at each Air/Fuel Valve position (Items 1 – 6). This drive
voltage adjusts the rotational speed of the blower to maximize
combustion efficiency.
Permits selection of the Air/Fuel Valve position (% open) to be
set from 0 to 100%.
Permits the DC drive voltage to the blower to be monitored.
Permits the Standby Voltage to be set from 0 to 4.00 Volts.
Permits the combustion oxygen level to be displayed (0% to
25%)
