Work great, used with Caleffi manifolds
I bought these in 2022. They are easy to install and work great on my Caleffi manifolds. Caleffi actuators I also used on some of my manifolds, installed the same time, had caps fall off and one of them failed. I am replacing that one with Bluefin.

Verified Reply- Supplyhouse.com TeamSupply House has no installers or technicians on staff to advise on proper installation. Bluefin is one of our overseas manufacturers from China and they provide little information in regards to installation besides the Product Overview below. Please contact a local electrician if you have further questions. https://s3.amazonaws.com/s3.supplyhouse.com/product_files/Bluefin-HMACT4-Product-Overview.pdf

Q: Is it possible to wire in two of these actuators together for a single zone? I will have two runs of 1/2 inch pex in each zone.
