Fibaro Smart Implant to open or close a 220v circuit

[widameista]

Szenario:
in my bath i have a typical thermostat which controls a valve in my cellar.
Technically the thermostat is switching an 220v output on/off, this opens/closes the valve.

I would like to let everything as is, but want to be able to completly deactivate the activation of the valve.

My idea was to use a smart implant and connect the 220v line (brown) to out1.

Is this the correct idea?

@widameista

Is this the correct idea?

“Maximum voltage on outputs 30V DC / 20V AC”

So no, that’s not the correct idea. Also, the implant switches between the inputs (IN1/IN2) and the outputs (OUT1/OUT2).</s<

i’m not switching 220v, im only interrupting the line. i could also interrupt the blue line

[widameista]

i know, this is forbidden in germany

any other way to achieve what i want? i do have shelly1 and shelly+1 and some fibaro switches as well…
I’m just struggling with the fact, that the input i get is already switched and not constant…

Yes you really do switch 220V
Interrupting 220V = switching 220V

When the max. Voltages Robert mentioned are exceeded, implant will probably die.

To switch the 220V line, you’ll better use a switch which can handle 220V
For example Fibaro Smart Module FGS 214

I guess I don’t know what the difference is between “switching” and “interrupting” I’m quoting the manual that states the maximum voltages on the outputs, but feel free to try out putting 220V on them.

[widameista]

ok, so with a shelly+1 it could look like that?

• some flows to control the valve when switch is on/off

[Peter_Kawa]

@widameista

shelly+1

Yes, this one can switch 220VAC.

I do have some questions though
What switch is used with the thermostat ? Is it a “dry contact”, or does it output 230V?

What thermostat is it btw?
I don’t know of thermostats powered by 220V, but that could be me.

[widameista]

It’s a jung tr ud 231

[Peter_Kawa]

Ah, we learn every day

The connector (24) can be used to connect an external sensor.
It is not a switch output.

I don’t understand (yet) with which connector the valve is connected at the moment;

Is it connected as ‘17’ ? Is that the valve?

[widameista]

Yes 17 is the valve.

Fun fact: normally JUNG instructions are very accurate but in this case 17 is not explained.

[Peter_Kawa]

I see.
I’m still unsure how it works.
The symbols are not clear to me.

Just being careful, because it’s about 220V.
So,
L = live
N = neutral
But what does the arrow stand for:

[widameista]

i guess the arrow stands for “switched output”, actually it’s what it does.
I realized my target with a shelly 1 according to this picture:

thank you
