Hi All,
I have been a reader of the firum and most times I have found the answers to any questions that I have had, so thanks to all the members who post some brilliant stuff here.
I have a generic question. I am trying to understand how th heating system at my home works so I gathered information by looking at whats installed. I think I have now fair enough idea whats installed. When I look at the wiring diagram (see attached RTS1) for the room thermostat it shows 3 L and N. Can any one please tell me what 3 stands for and similarly on the cylinder thermostat HTS3 what do number 1 and 2 mean. Is this a standard notation that I can find somewhere. Thanks you.
