DESCRIPTION
Displays the default DC drive voltage provided to
the blower at each of the Air/Fuel Valve positions
show in the left-hand column. 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%)
