Yesterday I heard/noticed the steam boiler pstat on one our Lineas acting weird. Instead of it's normal .3-.4bar deadband it was constantly toggling .1bar on/off, and of course much more frequently. Fiddled with it's adjust and it raised/lowered pressure fine, but kept .1bar toggle. Then suddenly today about 24hrs after noticing the behavior it would back to normal deadband swing. Talked with my goto for help tech and he's never seen this. Anyone ever seen this behavior on a Sarai or any other pstat for that matter?
To be on the safe side I do have a replacement ordered.
