The following keystrokes initiate the auto-tune function: 
 
1)

 

Press and hold the Enter key until the Status Menu changes to the 
Temperature Input menu. 

2)

 

Press and hold the Enter key again until the Temperature Input menu 
changes to the Parameter Input menu. 

3)

 

Press  the  Enter  key  three  times.    The  display  should  read 
AUTOTUNE off. 

4)

 

Press the Up key to change off to on. 

5)

 

Press and hold the Enter key until the parameter input menu 
returns to the Status Display. 

6)

 

Press the Start key once.  The left most display character will show 
the letter A until the auto tune is complete.  The ThermoCube will 
then begin controlling at the set point temperature.

For  users  well  versed  in  PID  theory,  Solid  State  Cooling  Systems 
recommends  the  closed-loop  “Ziegler  Nichols”  method  for  manually 
tuning the controller.  The method consists of three steps: 
 
1)

 

Turn  off  both  the  integral  and  derivative  terms  for  heating  and 
cooling by setting I1, I2, D1, and D2 to zero.   

2)

 

Set proportional band to 50 °C.  Begin controlling the process at the 
desired set-point temperature.  Look for a small-sustained oscillation 
in the coolant temperature.  Observe the status menu operating mode 
character  and  note  if  system  is  heating  (+)  or  cooling  (-).    If  no 
oscillation  occurs,  lower  the  proportional  band  in  50%  increments 
until a small oscillation occurs.  Write down this proportional band 
setting (P) 

3)

 

Measure the “Natural Frequency” (t) of the system in seconds.  This 
is the time required for the temperature oscillation to cycle from one 
maximum temperature to the next maximum temperature. 

 
Now set the controller input parameters as follows: 
 
P1 HEAT = 2*P if system was heating in step 2. 
P1 HEAT = 4*P if system was cooling in step 2. 
I1 HEAT = 1.2*t 
D1 HEAT = t/8 
P2 COOL = P if system was heating in step 2. 
P2 COOL = 2*P if system was cooling in step 2. 
I2 COOL = 1.2*t 
D2 COOL = t/8
