What are they? I just received my Duetto a few weeks ago and now there is already a new one from what I read... Am I missing out on something :shock:

(I have the European 220V version. PID 1.02)

Check bellabarista? New PID and SSR, new feet - the description is a bit fuzzy though. Chris Coffee has pictures of a new version without pressurestat i.e. PID control for steam and brew boiler with the new feet.

From Chris' Coffee:

PID controller also controls the steam boiler. (No pressure to fail)
Can program the offset for both boilers. (Makes for easy increase of steam boiler pressure)
The first you will probably notice is that we are having Izzo insulate the steam boiler and add additional vents both top and bottom to promote cooling inside the machine. This will help to prolong the life of the electronic components inside the machine.

And from Bellabarista:

New PID control allows better and easier control of Brew and Steam Boiler Temperature control New additional SSR relay to control to lead the temperature much quieter New smart aluminum feet

and...

1. No more pressure stat: both boiler's temperature water/steamer and brew are now controlled by a special super PID able to check 3 probes and once.
2. Two SSR relay: one for each boiler to assist the PID's accuracy in this job.
3. Boiler's priority: you may program the off set of each boiler as well as which one you want to get electrical power prior.
4. PID limit: just a security option for highest water/steamer boiler's temperature setting, so that you may not overcame °C 128 or °F 262,4, corresponding to 1,5 bar into the boiler
5. OPV rerouting: OPV water waste back into the drip tray, no more caring for the reservoir overflow when you plumb the machine to mains water.
6. Vacuum breaker valve: no more danger of steam/drops sprinkled inner the machine environment; it goes back to reservoir.
7. Boiler's hook: both boilers are now hooked to the bottom grid, no more movement during the transport.
8. Boiler's on/off switch: we kept the previous button on the machine's side to quicker easily use the Nuova Duetto economically.

Neither site has mentioned whether the PID sensitivity is still in units of 1F or more sensitive than that.

The new Duetto is shaping up to be quite a package. I guess all will be revealed in the next few weeks when the Duetto 2/Nuova Duetto is released.

I guess the good thing is that none of these changes are likely to make a big difference in the cup. I wish I had the OPV re-routing etc for convenience and durability though.

Whats the benefit to having a temperature controlled steam boiler?

And, if your electronics are properly isolated from high heat, good SSRs are somewhat more reliable than pressurestats, and cheaper to replace--as I understand it.
