Call for heat enable with smart pumps

hot_rod

If you zone with TRVs for example you need to call on a boiler or control when the pump starts to rev up.
Nathan up in Alaska found this adjustable induction relays that can be used for that call. Run the pump power thru the relay, it senses current and closes a contact.

We have added a function to Gen 2 relays to allow that as well as a set of dry contacts tied to zone one, for two temperature operations, etc. These functions, and a bunch others, were all requests from installers looking for wiring solutions.

I can use that right now for a recent install where I have 7 Danfoss TRV's and a Grundfos Alpha. Thanks.
