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. ![2024-12-04 15_17_40-Präsentation1 - PowerPoint](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/1/e/1e3ce4fdfd5e75c2afd9f9fe929b904fb7d7dad4.jpeg) Is this the correct idea? ---

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 ![1000038397](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/9/a/9a273eee21bc073f6764ef9489212e80049c7aee.jpeg) ---

> [@widameista](#): > > i’m not switching 220v, im only interrupting the line 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. ---

ok, so with a shelly+1 it could look like that? ![2024-12-04 16_15_11-Präsentation1 - PowerPoint](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/6/3/63b80602cbced807ffcc04d26fe56fa84648b145.jpeg) - some flows to control the valve when switch is on/off ---

> [@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. ---

Ah, we learn every day 😉 The connector (24) can be used to connect an external sensor. It is not a switch output. > ![1000038403](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/c/8/c89208af30e91d5910f73b21bfba65d575ca70e1.jpeg) I don’t understand (yet) with which connector the valve is connected at the moment; Is it connected as ‘17’ ? Is that the valve? ![1000038406](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/f/e/feb8cbf198a062cf28f7f2b09cfc519c310da531.jpeg) ---

Yes 17 is the valve. > **[Thermischer Stellantrieb 230 V, alpinweiß | TSA 230 NC WW](https://www.jung-group.com/de-DE/p/Thermischer-Stellantrieb-230-V-alpinweiss/TSA-230-NC-WW)** > > Bestimmungsgemäßer GebrauchThermischer Stellantrieb zur Betätigung von Heizungsventilen für eine EinzelraumregelungFür Regler und Thermostate mit schaltendem Ausgang, Zweipunktregelung oder Pulsweitenmodulation (PWM) ProdukteigenschaftenStromlos...

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: ![1000038432](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/c/6/c68cf752838fc0808dec3abf9240d7e16ea28d19.jpeg) ---

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: ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/0/4/04fa7495289dd50c7ae6cecc02ed645c95ba924a.png) thank you
