9.2.Span Adjust Screen
Using the up and down keys a factory technician can adjust the span calibration from -99
to +99. Span calibration should be adjusted with an input of approx 375 degrees to the
meat thermocouple input. The M: 375 is the value the control thinks it is seeing on the
meat input. The -4 is the amount we are adding or subtracting from the reading to make
it read correctly.

10.CONTROLLER INDICATORS
(From top to bottom)
1. Power – energized when power is applied, is not energized in monitor mode
(internal 9V battery power).
2. Power Draft – energized when the fan is on.
3. Ramp – Energized when the ramp is set to on.
4. In Range – Blinking when the control and handheld are within communicating
3. Ramp – Energized when the ramp is set to on.
4. In Range – Blinking when the control and handheld are within communicating
range and no interference is present.
5. Out of Range – Blinking when the control and handheld are out of range or
significant interference is present.
6. Error – Energized when an error is present such as the meat and pit temperature
errors.
11.CONTROLLER BASE STATION IN MONITOR MODE
The ProCom 4 is a stand-alone temperature monitor and will run on it’s own internal 9
volt battery.
In order to use the ProCom 4 as a controller, 12 VDC power must be plugged in to the
Base Station. This supplies power to the Power Draft Fan.
When 12 VDC power is plugged in, it overrides the 9 volt battery.
Note: The 9volt battery is for monitor mode only and will NOT run the Power Draft Fan
and all control parameters will become inactive.

13.DEFINITION OF TERMS
Offset – This value is added internally to the pit setpoint. Say your pit setpoint is 225
and you find that the actual pit temperature never gets over 220, you should add 5
degrees to the offset value (if it was 10 make it 15). This will make the actual pit
temperature climb another 5 degrees and agree with your setpoint. The default value of
10 degrees will work well with most pits.
Proportional Band – This value is the band of temperature over which the power draft
fan will pulse. Say your internal pit setpoint is 225 (215 + 10 deg offset). Below 200 the
