PID Tuning
Each installation has different conditions of operation (ambient temperature, water
temperature, different fluid loop length, etc.), therefore the factory PID settings do not
always provide optimum control at the required temperature setpoint.
Use the instructions outlined below and adjust the PID settings to the values shown at
below.
To get to the menus press and hold the Up or Down button. 1.
Once in Program Mode use the Up and Down buttons to move between 2.
menu headings.
When PID is displayed, press I/O. 3.
Once inside a menu, use the Up and Down buttons to adjust the value of 4.
parameters. The I/O button accepts the value displayed and steps down to
the next parameter in the menu.
After the last parameter has been stepped through, you are returned to the 5.
Operational Mode.
The following pages contain the basics of how to go from the values at right and tune
the unit for your specific application. In most cases it is sufficient to calculate a new
Integral Time (It) and enter that into the controller.
