Posted Thu Jan 10, 2013, 4:04pm Subject: Improve Rancilio Silvia temperature control without PID
I was wondering if I could achieve better temperature control in my Silvia without investing time and money into PID mod. Before every espresso shot, I run some water through the machine to cycle the boiler, clean old coffee grinds from portafilter and warm up the cup. Normally after light goes off, I wait for 30 seconds or so, for the machine to drop to optimal brewing temperature. I would really like to remove that 30 second wait. Can existing button thermostat be replaced with one that has lower temperature setting, so that machine is closer to optimal brewing temperature right after the light turns off?

Bimetal thermostats still have a large deadband of on to off click. You will still be cycling up and down and, IMHO, need to adjust the temperature. The flush is also useful for group temperature since the group is not directly over the boiler.
