Alter the red display using the up/down buttons
to show the new required set point, press exit or
let the unit time out to return to the basic display
which should be the new set point figure.
To enter a new parameter
The parameters dictate the way in which the burner
firing rate alters in response to changes in the
pressure/temperature of the boiler.
A major factor that determines the need to change
the parameters is if the burner is fitted to a steam
or hot water boiler. The table on Page C.18
indicates the parameter and its setting for steam
and hot water boilers. It must be emphasised that
it is only an indication and any departure from
these settings should be made in small increments,
with time given to see how the burner is reacting
to the changed parameter.
Press and hold the PGM button down until the
green set point figure changes to an AL, the larger
upper figures show the value. Use the up/down
buttons to set the new value, press the PGM button
to enter the value and change to the next screen.
To cancel an entry press exit. Scroll through the
screens, (PGM button) modifying any value found
to be in error (up/down buttons). At the last screen
the PGM button will return the controller to the
original operating display.
At any point in the procedure the original
operating display can be obtained by letting the
unit time out, the value in the display at the time
out will be accepted.
A value can only be altered within the permitted
range of that parameter. All other parametrs must
remain as supplied.
Note: The detector range parameters SCL & SCH
are given as °C for Hot Water (temperature) and
bar for Steam (pressure).
