On the next page is an illustration of the program profile and
a table of the parameters entered.
Basic Ramp and Dwell Parameters:
1.

then press and release the 'SET/ENT' button twice to
enter this new value and to advance to the "StC" display. If
the value for "SSP" is correct and does not need to be

to enter this value and to advance to the "tMI" display. If
the value for "SPl" is correct and will not be changed, press

with the arrow buttons. Press and release the 'SET/ENT'
button twice to enter this value and to advance to the next
display.
6.
The next parameter, "tM2", represents the second time
period used to maintain or dwell at the target setpoint

Additional Program Parameters"
10.
The next parameter displayed is "tM4". Select a lower
display value of "oFF" with the ‘arrow’ buttons, then press
and release the 'SET/ENT' button twice to enter this value
change and advance to the next display. ·

The next display shows "EVl" in the upper display. The
lower value should always be "0" (zero). Press and release
the 'SET/ENT' button once to go to the next display.
12.
"ALl" should always have a lower value of "9". Press and
release the 'SET/ENT' button once to advance to the next.
13.
The next parameter, "AI", is used to select the high
temperature alarm trip setpoint. Use the ‘arrow’ buttons to
select a value 10°C (or 20°F) HIGHER than the highest
target setpoint to be used. Select the High Temperature
Alarm value with the arrow buttons then press and release
the ‘SET/ENT’ button twice to enter this new value and to
advance to the "HYl" display. If the value for "AI" is correct
and not changed, press and release the 'SET/ENT' button
once to advance to the "HYl" display.
14.
"HYl" is used to select the amount of temperature change
below the high temperature alarm setpoint where the alarm
relay will reset. This value is usually "I". Select "I" with the
arrow buttons and press the 'SET/ENT' button six times to
enter the correct value and advance to the "JC" display. Or
if the value is correct, press the 'SET/ENT' button five times
to advance to the "JC" display.
15.
For the parameter displayed as "JC", select "I" with the
arrow buttons, then press and release the 'SET/ENT' button
twice to display "WTZ". Selecting the value of"I" will cause
the program to hold the setpoint at this last segment. A
value of "0" would cause the program to reset and stop
running the program and stop the power to the heaters. A
value of "2" will cause the program to repeat 'continuously'.
