the top and snapped into place. The module uses two
lines of 16 alphanumeric characters each, to display
the control variables.

Operation
The display was designed to function as both a
monitor and a programmer. The display consists of
two rows of 16alphanumeric characters. Below the
display are 4 keys:
The Back key is used to step back
through the display screens or to reply 'no' to a
question.
The Select key is used to advance
through the display screens or to respond yes to a
question.
Use this key to scroll back to the
previous screen, to decrease pre-time and post-time
timing, and scroll through the character sets when
customizing the Service Message screen.
@Use this key to scroll forward to the next
display screen, to increase pre-time and post-time
timings and to scroll through the character sets when
customizing the Service Message screen.
There are five main functional display groupings within
the module; Burner Status (Paragraph A), Burner
History (Paragraph B), Pre-time Change (Paragraph
C), Post-time Change (Paragraph D) and the Service
Message Program (Paragraph E).
A. Burner Status Mode

example, when the burner is idle, the control
will display Standby followed by the number of
minutes the burner has remained idle (up to 1
hour). The second row of characters displays
the cad cell resistance in ohms and the line
voltage. Note that if the cad cell resistance
is greater than 50,000 ohm, the screen will
display >50 kohm and if the line voltage is
between 0 and 83 volts, the screen will display
<84 volts..
As the burner cycles through PRE-TIME,
TRIAL FOR IGN (Trial for Ignition), IGN
