Folks
I have to rewire the controls for a large central heating system. I have most of the challenge covered but one thing is puzzling me. Fitted to the pipework are two Teddington pressure differential switches. One set at 15Psi with a diff of 10 and the other at 45 Psi with a diff of 30. I presume that these switches allow for safe operation but can anyone confirm this.
Thanks
Mark
