valves for heating lines

[ropske]

Hello,

someone already made an installation that controls valves (12VDC / 24VDC / 230VAC) of the heating lines connected to a pipe divider (collecteur)?

All my rooms have seperate lines going to my collecteur and instead of using battery powered danfoss valves, i'm thinking of controlling all with fixed powered valves directly on my heating lines.

I'm searching what valves i need to buy (i prefer 230VAC)
I have external thermometers in every rooms so i can use a Multi zone heating system

Will use the one from Egregius :p

Anyone can point me in a good direction? Thank you

Not so hard you need a relay board and motorised valve
Hard part is to :
- Get valve who fit to your manyfoild (collecteur en anglais), each 3 or 4 differents possibility.
- Get a thermostat script rock solid (got some on french forum)

Thanks for your answer deennoo

I don't know what kind of valves there exist and what brand is best.

My thermostat script is almost finished, i used the one from Egregius and adjusted it to my rooms/needs.

That's why i need to choose between danfoss/popp valves (battery powered) or the fixed valves (mounted on pipe lines at collecteur)
Personally i think the first idea would be better, but more work (relay board i can manage, but the valves ...)

The second one is the easiest

Do you have a brand of your manifoil ? You have to take motorised valve who fit :
Brand for brand

Gonna reply and bookmark this topic, interesting

Also searching for a more decent solution instead of the Danfoss valves.
Problem with them is the lack of battery status resulting in malfunctioning without notice.

My manifold is from Begetube, but the valves in it need a hex key to open/close.
If I understand it correctly you need a manifold with the small pins like on a thermostatic radiator valve. Like these:

Thanks guys

all heating pipes and manifolds are installed in a cabin that is isolated in my garage.
I will open it tomorrow to see what unit it is.

So if i understand correctly: i will need to change my manifold in a manifold that can control those pins? (these are indeed like in the radiator valves)

and then install valves on them to control this pin?
Or am i looking to difficult? :p

[deennoo]

I'm a kind of plumber you don't have to change manifoild.

Juste to know
Which brand it is, what is lenght course (the little chrome part pin, when press this close the valve, when release this is open).

Then you have to found which one is the main filet (filetage) the part where the motor is screwed

Usually it is m30x1.5 but can be m28 or else

You have choose if you want a motor or a dilation parts.
Motor make noise.


230/24/12 no matter with this but 12v/24v s a way secure for DIY solution.

You have to think about : if homeautomation is dead ? Rpi and sdcard arn't the best.

You have to choose motor valve who can be unlock quicky (quart de tour) Eberle TS+ brand to this right.

I first tought this would be something to handle during summer when the heating is not needed.
But, for some reason it's freezing -7°C here (not usual where I live), and the Danfoss LC13 valves are acting strange on that.
When the heater is stopped because temperature is reached the temperature around the valves drops so quick that the 'open window' function kicks in. This results in a closed valve for 30 minutes, even when they are set to 28°C
Of course, as a direct result of that the room doesn't heat anymore when the heater is on.
Arrrggghh, automation is fun

[ropske]

lol :p

can you actually disable the 'open window function'?
Or can you see somewhere the status of this?

these are the settings i have (see attachment)

[Egregius]

Not that I know.
And see? Not really, you feel it because it's getting cold. Then you check the valve and the settings is at 28° while it's closed.

[ropske]

You now what the override state is?
i can choose between: none / temporary / permanent
and then you also have override setback (now at 127)

[Egregius]

No, I only set temerature with my radiator function to a temp depending on difference.

[ropske]

mine are also from begetube

what is the next step i need to do?

what kind of valves i do need to buy? and there need to be a valve installed in both lines? (blue and red)? or only at 1 pipe/room?
the pictures you can see are not the pipes for heating but for my warm water.

but the pipes for heating my rooms are on the same brand of manifold (begetube)
and there 7red ones and 7blue ones

thank you

[Egregius]

You'd better look at the manifold of your heating. Aren't there screws on top of it?
Mine has caps, if I remove the cap there's a hex key to close the valve.
Next time I need to let the water out I'll try to remove one so I can search the right size with the small nipple instead of the hex key.

[deennoo]

This is what is needed, white caps are motor. White box are relay board.

That for underfloor heating.

Changing manifoild is a plumber job, you need to draw water, cut tub, fit manifoild, empty water, and made the customisation for flow rating...
