So my heat only boiler has two low-voltage terminals for the frost stat. If left open the boiler will turn on so if there is no frost stat present a link needs to be put in to join the terminals. But I want to put in a frost stat .....
I've been scratching my head wondering how am I going to connect up a regular Drayton frost and pipe stat. I think I've figured it out but is this the normal way of doing it ? It seems complicated even though I have managed to do it without extra relays etc.
Please see attached I hope its self-explanatory. It should say "Boiler Connections" and I've only shown the 2 relevant ones. For the boiler to turn on, I think both stats need to be calling for heat which is the same for regular S-Plan systems I think...
Note that my existing Drayton Frost Stat doesn't give access to the "satisfied" terminal so I plan to buy another which does. The pipestat does give access to all 3 terminals (Common, Satisfied, Call) so I think I can reuse that.
