Table 1 lists default settings for the SV of the controller. Based on the discussions from forums, 
the generally accepted setting for Silvia PID has been around 228-229 ºF for sensors mounted on 
the top of boiler.

 

The values in table 1 have been adjusted for the RTD sensor. We found the 

temperature in the thermowell is about 2 

º

C (3.5 

º

F) lower than that on the top of the boiler after 

the machine is equilibrated for 45 minutes or longer. Since SV can be easily changed, it will up 
to the user to decide what the best temperature is for the espresso.  

 
Recommend PID Parameters with PT100M sensor

For the current model of SYL-1512, you can try the following setting. 
SouF=1.0, P=3.0, I=100, D=40 
SouF=1.0, P=3.3, I=183, D=45 
SouF=1.0, P=4.0, I=200, D=50 
Please note that these numbers only apply to RTD sensor. They are independent with the 
temperature display unit. Either F or C will work.
