Hi
The original Sirai 2 pole pressurestat in my Cellini Classic has failed after 4 years.
I cannot find an exact replacement (Sirai P203T01) here in Canada.
I am wondering if I can use the newer model Sirai 2608 which is a three pole pressurestat.
The Cellini Classic has two wires leading to the pressurestat.

Yes. Should work fine. You just end up with an unused contact. Provided it will fit inside your case.

The Cellini Classic has two wires leading to the pressurestat.
If the existing Sirai only has a grand total of two wires (one in, one out), then simply move those two wires to the second set of contacts which have never been used.

BUT, that, by itself, may not be your problem. As far as I know, all Sirai pstats are rebuildable, at least the diaphragm section.
Skål,

Love the thermometer by the way :)

Yes, it will work. I did the same for a Giotto Professional. It is a much larger pStat than original, but if rotated 90 degrees it works without a problem.
