For ease of use in normal applications, the CN9000A has been
pre-set with factory or Default settings (or Parameters). Section 3.5
discusses how to change these Default settings.
These pre-set Parameters enable the instrument to operate in the
PID Control Mode, with a single set point and slow cycle relay
output. This configuration should give good results where the
heater is adequately rated and the control sensor is located
reasonably close to it.
Default Settings (for SP1 only) are:
Proportional Time (Cycle Rate) = 20 seconds
Proportional Band (Gain) = 2.5% of Default full scale
Derivative Time (Rate) = 25 seconds
Integral Time (Reset) = 350 seconds
To use the controller with the Default settings requires only that the
correct Option number of the sensor. selected from Table 3-3,
Sensor Default Setpoint Range Table, be keyed into the
instrument. Also, check that the instrument is set to either °C or °F,
as required. (Refer to Function .22 in Table 3-4).
Also check that the desired control temperature is within
the Setpoint Default range. Refer to Section 3.4.2.

Selecting Sensor and Adjusting Setpoint
To operate unit:
Apply power. All LED segments will be briefly illuminated during
the self-check routine, then the display will request sensor
selection (from Table 3-3), i.e., the desired Option number for
Function .16, and will not respond to any further instructions until
this selection is made.
