PID control kit for Rancilio Silvia w/ Steam Control

This PID controller kit has all the features of our other listing titled "PID temperature control kit for Rancilio Silvia, Deluxe" with the addition of steam temperature control. The steam temperature is controlled by the same controller that controls the brew water temperature. To the user, the operation is the same as regular machine; no extra button is needed to press for frothing. When the steam switch is turned on, the on/off temperature of the heater is controlled to 1 degree (F or C) difference as compared with original thermostat's 20C (or 40F) difference. With this tight temperature control, you might not have to surf the temperature for frothing because the heater will kick on much sooner than the original thermostat.  The on/off temperature can be adjusted by the user.

This kit will take additional 15-30 minute to install because extra steps to access the steam switch. The installation is completely reversible if you ever want to sell the machine or send it to service. No relays or diodes are needed for this feature addition. For the buyer, the only thing added are two pre-terminated wires for connecting the steam switch to the controller.
