Silvia PID Installation Guide
Part C
Version 96-2.04
visual indication of the action of the PID. When Silvia is very near the chosen set point,
the controller will apply power for only a small fraction of each second.
Because of the sophisticated PID algorithm built into the digital controller, you should
see very little "overshoot" in the temperature as it reaches the set point. Once the set
point has been reached and the system stabilized, the controller will typically keep the
temperature within a range of +/- 1 degree from the set point (although small, temporary
deviations are of no concern).
Under some circumstances, particularly after a shot has been pulled and Silvia is heating
back up, you will see the temperature overshoot its mark by 1 or 2 degrees. This is
normal and is no cause for concern. It will stabilize back to the set point within 2-3
minutes.
Changing the Set Point
You may change the current set point at any time using the arrow buttons on the front of
the Watlow Series 96 controller. Simply press the "up" arrow to increase the set point
temperature, and the "down" arrow to reduce it.
For complete operating and programming instructions, please refer to the manufacturer's
users' manual that is included on your CD.
Steaming with your PID'd Silvia (no steam package)
Your new controller will only control the unit in "brew" mode unless you have also
installed the steam control package (see below). When you switch to steam mode, Silvia
will bypass your new controller and steaming temperatures will be controlled by the
original steam thermostat – exactly as they were before you did this installation.
But your new controller, since it will continue to display the actual boiler temperature,
can still be very useful while in steam mode.
