Rocket Cellini Delta Unit/Low Steam Pressure
Hey y’all, I have this older Rocket Cellini that I bought used years ago. It’s a fantastic machine and has served me well but recently I realized that I don’t really know what this little Delta PID unit does in the bottom right of the picture. If I set the SV number higher,my group head temperature raises to above 205 to 210° and my steam pressure increases on the left side. Does anybody have experience with setting these properly or is there another adjustment I’m missing on the actual machine to increase the steam pressure but keep the group head at a specific set value. I know this is a single boiler machine so the two are connected but wondering if this unit can be used to dial in the machine a bit more. Is there an OPV that needs to be adjusted or something else I’m missing?
