Silvia PID Installation Guide
Part A
Version 2.04
A short discussion of thermocouple placement: it is theoretically possible to locate your
thermocouple just about anywhere on the surface of the boiler. We recommend,
however, that you closely follow these instructions and mount the thermocouple where
shown. We have measured temperatures at each of the three screws that fasten the two
factory thermostats on the top of the boiler and consistently found as much as 10F
variation from screw to screw. The screw we recommend for use (the one on the far left
as you face the machine) is always the hottest of the three. Normally, the rightmost
screw, closest to the large brass fitting for the cold water supply, is the coolest.
If you attempt to compare your installation to another PID installation that you might
read about on the internet, be sure you know where the other installation's thermocouple
is located. Otherwise, you will not be able to directly compare readings, due to the 10F
variation described above.
Locate once again the brew thermostat (red dot). Now locate the left most screw that
secures the mounting clamp for this original brew thermostat.
Loosen this screw, taking care not to drop into the neverland of the brew group. A pair of
needle nose pliers is helpful here.
