Pid Controller Advanced Settings - Chris Coffee Service Silvano Owner's Manual

PID Controller Advanced Settings

 These instructions will allow the user to change the temperature from Fahrenheit to
Celsius as well as other advanced settings. It is not recommended to change the
advanced settings unless the user has a thorough understanding of how a PID
controller operates.
 To change the advanced settings, with the machine turned off hold down both arrow
keys and then turn the main power switch on. When
display then release the arrow keys.
 Press the up arrow key to select and change the existing setting.
 After changing a setting you must wait a few seconds for the display to revert back
and then you can press the down arrow key to cycle to the next setting.
 To save the new settings turn the machine off and then back on again.
Fahrenheit Or Celsius Mode
Proportional Value
Integral Value
Derivative Value
Offset (temperature between boiler and group)
 The PID calculation algorithm involves three separate constant parameters, the
proportional, integral, and derivative values. These values can be interpreted in
terms of time: P depends on the present error, I on the accumulation of past errors,
and D is a prediction of future errors based on the current rate of change. These 3
settings work together to determine when and how to apply power to the heating
element.
 The PID controller allows for a more precise temperature control than a traditional
thermostat or pressure stat controlled system. It also enables you to quickly and
easily change the brew temperature to match your personal tastes.
 The offset is the difference between the temperature drop from when the water
leaves the coffee boiler and then hits the coffee. This setting has been calibrated
using a Scace device and should not be changed.
