Ale Posted May 21 Share Posted May 21 There is no information about if I can use the internal Rele as a "Dry Contact Rele) with some special wiring to contect directly to a Radiant Boiler Heating! If not, which reles (like 1 PM plus) has this capacities ! Thanks! Quote Link to comment Share on other sites More sharing options...
Members thgoebel Posted May 21 Members Share Posted May 21 Sorry - the internal relay of the Wall Display has a fixed connection to the live terminal (L). Hence, the relay cannot be wired like a dry contact. Shelly plus 1 has this capability. And Shelly Mini 1 - in the case the switched circuit is operated with the same phase.

Ale Posted May 21 Author Share Posted May 21 Ok, clear! ... I guess 1 Plus PM (which is used as example in the uses cases for for heating boilers in this page) also? How is the diagram connection in this case? Thank you very much for your help! Quote Link to comment Share on other sites More sharing options...
Members thgoebel Posted May 22 Members Share Posted May 22 A second sorry: The Shelly plus 1PM (or the old Shelly 1PM) are NOT equipped with relays having dry contacts! Please refer to my enumeration in post #2. 1 1 Quote Link to comment Share on other sites More sharing options...
