"Hi this is my first post on the forum. \n\nI found this device when preparing my van after the winter. We only got it last year but do not know its precise purpose. I assume that its to do with the Gaslow system we have installed but i have no documentation or information. Have had a look on the web but not found anything. Can anyone give me some information perhaps?\n\nThanks for your help."
