Digital Temperature Interlock
Calibration
The temperature controller is preset by the factory to
turn the fans on at 95°F. This is controlled by the set
point on the temperature controller. The temperature set
point may have to be adjusted slightly depending on
both ambient and cooking conditions. The adjustment is
made through the buttons on the temperature controller.
The controller is capable of monitoring two separate
sensors. If more than one sensor is utilized with a single
controller, two set points can be adjusted. To adjust,
follow these instructions:
1. If setting set point 1 (St1), press
Set
. The display
shows St1 and then the current value of St1.
If setting set point 2 (St2), press
Set
twice, slowly.
The display shows St2 and then the current value of
St2.
2. Press the
S
or
T
to change the set point.
3. Press
Set
to confirm the new value of either St1 or
St2.
4. Check system operation before making additional
adjustments.
Factory Selected Parameters
The factory will pre-program the controllers to be
properly integrated into the control panel. Except for
the set points, the other parameters should never need
adjusting. However, there are three different types of
parameters that are accessible on the controller. Access
differs depending on the type: set point; frequently used
parameters (P); and configuration parameters (c, d, F).
Setting type P parameters
Type P parameters (frequents) are indicated by a code
beginning with the letter P, followed by one or two
numbers.
1. Hold the
Prg
mute
button, after 3 seconds the displays
shows the firmware revision code (e.g. r2.1) is
shown, after 5 seconds (in the event of alarms, first
the buzzer is muted) the code of the first type P
modifiable parameter, P1.
2. Press
S
or
T
until reaching the desired parameter.
3. Press
Set
to display the associated value.
4. Increase or decrease the value using
S
or
T
respectively, until reaching the desired value.
5. Press
Set
to
temporarily
save the new value and
return to the display of the parameter code.
6. Repeat operations from 4 to 5 to set other
parameters.
7. To
permanently
save the new values of the
parameters, press
Prg
mute
for 5 seconds, thus exiting
the parameter setting procedure.
Setting type c, d, F parameters
Type c, d or F (configuration) parameters are indicated
by a code beginning with letters c, d, F respectively,
followed by one or two numbers.
1. Press
Prg
mute
and
Set
together for more than 5
seconds. The display shows the number 0.
2. Press
S
or
T
until displaying the password: 77
3. Confirm by pressing
Set
4. If the value entered is correct, the first modifiable
parameter c0 will be shown, otherwise the standard
display will resume.
5. Press
S
or
T
until reaching the parameter to be
modified.
6. Press
Set
to display the associated value.
7. Increase or decrease the value using
S
or
T
respectively, until reaching the desired value.
8. Press
Set
to
temporarily
save the new value and
return to the display of the parameter code.
9. Repeat operations from 5 to 8 to set other
parameters.
10. To
permanently
save the new values of the
parameters, press
Prg
mute
for 5 seconds, thus exiting
the parameter setting procedure.

NOTE
The controller is pre-programed at the factory to
operate with the digital temperature interlock
components. No further parameter changes should
be necessary.
