Help me understand UFH actuators… (idealy 0-10v proportiona)

[ringi]

(I am thinking of using them with a radiator based system with lots of zones, so will not have the thermal mass of the floor to even out the response.)

I know that there are 3 types, 240v, 12v (or 24v) and 0-10v proportional.

Firstly I have seen that at least some actuators take 3 minutes to open when they are powered. How does such a slow response allow a TPI thermostat to work, or any thermostat to keep the temperature constant in a room?

How do I control a proportional actuator, it seems that standard thermostats don’t support them?

Given a choose I would like a fully wired system, as I don't trust wireless to remain pain free and the building is at a stage where putting wires in is easy.

Depends on the controller. Decent ones learn the actions and respond accordingly.

You don't.


You're over thinking things.
