Control 

 

Note

: 

Relays P6-P9 must be set to ON/OFF Mode

See section 10.3 Enable and Configure a  
Relay

 

Each of the P6 to P9 and R1-R5 Outputs can be 
configured for PID (Proportional-Integral-Difference) 

control. PID control can also be used on 4-20mA 
outputs. 
We highly recommend Timed Cycling or Time 
Modulate for control over PID because these 
methods are highly functional and simple to set 
up/understand. In most water treating applications, a 
full PID setup does not noticeably increase the 
control regulation of the process but is difficult to set 
up/tune. However, using only the proportional setting 
of the PID setup and leaving the others settings at 
default is easy and effective. 
If Relay outputs 1 to 5 are configured for PID control, 
they are implemented by continuously modifying the 
pump relay ON & OFF times.  
 
 
1.  To set and adjust the PID settings, press MENU 
2.  Scroll to the I/O Setup selection and press OK 
3.  Scroll to select the desired output (6:Chlorine 

Pump) and press OK 

4.  Scroll to Special Control and press OK 
5.  Scroll to PID Control and press F1 
6.  Use Up/Down and Left/Right Arrow keys to Edit 

Kp Proportional value then press F2 

7.  Use Up/Down and Left/Right Arrow keys to Edit 

Integral Rate value then press F2 

8.  Use Up/Down and Left/Right Arrow keys to Edit 

Difference Rate value then press F2 

9.  Use Up/Down and Left/Right Arrow keys to Edit 

Relay Period value (if P6-P9 is set to pulse 
output skip this step) then press F2

SPECIAL CONTROL TIP:  

When using Timed Cycling, Time 
Modulate or PID control, best results for 
tuning the loop are achieved if you only 
change one variable at a time and wait for 
two or three cycles to observe the effect 
of this change. This would include 
changing the stroke % of the pump and 
any setting in the special control program.
