Hello, I would like to equip our underfloor heating system with actuators and wireless receivers so that the temperature in the rooms can be controlled using wireless room thermostats. First, a basic question: does the heating manifold also need to be equipped with flow meters for this purpose? Our existing one does not have these meters. A second question: when replacing the actuators, can the old ones simply be removed and the new ones screwed on, or will water leak during this process? Thanks and best regards, Ashley

You need the R478 or R478M electric actuator from Giacomini.
Is there also an option for an adapter on which you can then screw other electric actuators with M30x1.5 threads? Thanks!

You can basically forget about the plastic stuff because it doesn’t last long, like the blue caps. Use the metal ones instead.

As long as it says they fit Giacomini manifolds, then they will fit.
