Resolving non-working thermal valve actuator

[Gast]

Hi,

I bought quite a few of these to use as valves in my house:

http://shop.loxone.com/enuk/valve-actuator-230.html

As far as I understand these actuators are digital outputs that control the heating. My electrician installed them. I connected them to the Q output on the intelligent room controller, however, they are off as far as I can see in the loxone config liveview, but the actuator is open and the room is heating non-stop.

These actuators click in place but nowhere I can see how to remove them. I don't want to force them out. I need to find where the problem is so starting by removing them would be nice.
Any suggestions on how to debug what's wrong? Is there any tool or way to find out if there's a signal from the miniserver arriving on the actuator?

Asking my electrician is not a good suggestion as he's on holidays for 2 weeks and only comes back afterwards to finish a few other things. I have some rooms at 27 degrees celsius so obviously if I can sort this out myself earlier rather than later it would be great.

Kind regards,

Paulo Matos

Firstly the square on the side is the release button, you may have to press the body in slightly to take the tension off the spring.
These actuators are usually designed to press in the valve pin when off, so is the threaded ring on the manifold ring fully screwed on? If not then the actuator can't press in the pin enough to cut off the flow.

It's very likely to be a mechanical issue rather than config or electrical. Are these on radiators or a manifold? If ufh then why didn't you get the ufh companies actuators which would definitely work and should be around £12-15 each.
Some manifolds are the other way, press to enable flow, not very likely but worth checking the manifold description

If liveview says they are off, then they probably are. Assuming your loxone relays switch 240v to the actuator, them remove the 240v supply to the relays and if nothing changes then it's mechanical rather then electrical or loxone related

Thanks Duncan,

I will give that a try and report back.

Thermal valves usually have a "before-first-run-open" features, means, they are open as long they never where switched on (to heat before a controller is connected). After they first get powered, they move to normal operation (close).
So they might have never get powered.

In Loxone Config, put one away from the IRC and to a push button block, and turn it on. After 10 minutes, turn it off, wait another 5 minutes and double-check, if it has closed.

If not, they possibly get no power, or it is a problem with the valve (or valve adapter).
