Setup and Operation

Connections

1.  Connect the thermocouple and heater power cord to the ITC2 rear panel. 

NOTE:  Take care to verify the polarity of the thermocouple input, as described below.

2.  Plug the power cord into the ITC2 and into a properly grounded outlet

3.  Turn the power switch to “On”.

On initial power up, the controller will go through a boot sequence in which the ther-
mocouple is checked for proper connection.  If the red temperature display shows “

nnnn

”, 

the thermocouple is not connected properly.  Turn the power off and fix the connection 
before proceeding.

When a proper connection is detected, the controller starts controlling at the setpoint 
indicated in the green LED readout.  The ITC2 leaves the factory with a setpoint of 20.0,  
so there will probably be no power applied to the heater until the setpoint is increased.

Adjusting the Temperature Setpoint

Use the up and down arrows on the controller (

Figure 3

) to select the desired  

temperature setpoint.

Verifying Thermocouple Polarity

To verify the correct polarity of the thermocouple input, increase the set point and verify 
that the temperature increases.  If the temperature in the readout is decreasing, the  
thermocouple is not polarized correctly.  Correct before proceeding.

Running Autotune

As mentioned previously, the controller utilizes a PID algorithm for configuring the best 
scheme according to the mass, power applied, and heat loss.  We recommend using the 
autotune feature to establish these values.  To learn more, refer to 

“Appendix A:  Operation 

Terms and Principles”

 on page 6.  All other functions of the controller have been factory set 

for optimum performance; it is recommended that these settings remain unchanged.

Autotune has two modes: Fast, for the shortest execution time, and Full, for maximum 
temperature stability. 

Initiating the Autotune Sequence:  Fast Mode

1.  Press hold the P key for five seconds.  “

Atun

” will appear in the upper red LED and “

oFF

” 

will appear in the lower green LED

2.  Momentarily press the down arrow.  When “

FASt

” appears in the lower green LED, press 

the P key again to select the fast mode.

3.  Press the P key eight more times.  At this point, the TUNE LED illuminates, the setpoint 

and actual temperatures are displayed, and the fast autotune sequence begins.

4.  Use the up and down arrows on the controller (

Figure 3

) to adust the temperature 

setpoint to the desired reading.  This can be done before the autotune sequence is 
completed.
