Pressure Switch Campini

I had a Mater pressurestat that was failing in my Rocket Appartamento so I ordered this Campini pressurestat with the RC filter (also sold on this site). I took off a star because at first install, the pressure was sitting a bit on the high end between 1.3 - 1.5 bars so I had to peel off the red wax material and adjust until it was dialed in between 1.1 - 1.3 bars. I don't know why they had sealed off the adjustment screw with a wax but that was a little bit annoying to deal with. Also turning counter-clockwise increases the pressure while turning clockwise decreases the pressure which felt a bit unintuitive for me. Otherwise, it's been installed on my machine for several days now with no issues so far.
