    Hi, I would like to ask for help with the connection of the fox shutter module.

    So far it looks like this. In the module:
    1 on the left is the wire from the shutter that raises it up.
    The 2 on the left is the wire from the shutter that lowers it.
    3 on the left is the N from the power supply. (all the N from the blinds clipped together with the N from the power supply, I added an extra wire to the cube and connected it to the module).
    The 4 on the left is the L from the power supply.
    Is this ok?

    The question is how to connect the wall switch now?
    If I connect the up/down control to the switch and then to the control unit in S1 and S2 (5th and 6th input from the left), what then? In the wall switch there is then one place left with the description L.

    I have uploaded a diagram and a real photo below.

    Added after 5 [hours] 21 [minutes]:

    ---- Update ----

    So far I've done the configuration via the app and it works remotely, but I still don't have the connector connected.

    Generally there is voltage on S1 and on S2 (5th and 6th from the left) all the time. Is a diagram like the one below OK? Is this how it should be connected?

    1 left - from motor, direction down
    2 left - from motor, direction up
    3 left - extra cable from the cube (all N from the blinds connected in the cube together with N from the power supply, I added an extra wire to the cube and connected it to the module)
    4 left - L from power supply
    5 from left (S2) - additional wire going in the down direction in the connector
    6 left (S1) - additional wire going in up direction in the connector
    There should be an L from the power supply (branched wire in the wago) connected to the connector in the L field?

    In this configuration there is still voltage on the switch in each of the 3 inputs. Surely it is only when the button is pressed that a particular circuit closes and the shutter goes up/down? Previously, the voltage on the switch was still on the L input, and only appeared on the directional input when the wall button was pressed. This probably blocked both directions from being accidentally pressed? Although the switch itself has a mechanical interlock, it is not possible to press both directions at the same time.

    I would appreciate an explanation. Thanks!

    The control is N, so it's drawn (red) not to L but to N (blue wire)

    Only then will the current go to the whole cube with the N connected together. There is still current on S1 and S2 in the module. When I connect S1 and S2 respectively in the directions to the connector, there is already a constant current on the directions on the connector. If I connect a new cable to the L on the connector and connect the other side of the cable to the N block, every time I press the connector the current is transferred to the N block. Is this OK?

    Checked with a neon lamp?
    If yes then it is fine.

    Yes, I checked with a tester. It doesn't matter what the module does or doesn't do, current is still applied to S1 and S2.
    From the L field in the connector, it doesn't matter if I connect to the N field in the module or the N collecting block?

    I just didn't want to blow up the blinds, and wanted to learn something at the same time :D .
    I wired as you wrote, but a strange thing happened with the switch. So far (without the module) when I pressed the down button it would travel down until I held the button. I let go of the button it would stop. That is, I was only applying current when I held down the wall button.
    Now, if I briefly (click it) press the down button, it goes all the way down without holding the button. To stop it e.g. in the middle of the window I have to click again. On the other hand, if I hold the button down for longer than a click, e.g. two/three seconds, it only moves for the time I hold the button down. What is the problem?

    This is a property of the controller itself (its software) nothing you can do about it.
    It works in a similar way to a car's el. window - you just have to get used to the way it is operated.

    Ok, so I didn't mess anything up that the switch got new functionality :D .
    As long as it is cool because if I want to lower a blind halfway from a wall button, I don't have to hold the button down, just click briefly and wait until it reaches the desired position and then click briefly again and it stops. When controlling the tilt of the slats, this is a bit of a nuisance. Turning the slats from horizontal to vertical takes about 1.3 seconds. When I want to tilt them halfway I have to be like a ninja, click quickly and click again so that they only turn slightly :D .

    I wanted to get back to the subject of this controller, it's all about directions.
    I control the blind "in the short term", i.e. I add a directional wire to the L of the power supply. I add the brown wire going down, I add the black wire going up. I plug the wires into the control unit in this configuration (brown wire going down in the control unit, black wire going up in the control unit) and it turns out that it works the other way round. What is the issue here? Could it be to do with the controller controlling the blind via N and therefore the directions are swapped? I have several control units for all the windows and it is generally the same in all of them so it is unlikely to be a manufacturing fault.

    Hello, I am writing because I have a problem with this controller. I have an installation in a new building made in such a way that all the wires go to the distribution board from the buttons and from the blinds (there were supposed to be blinds controlled by SUPLA SRW-02M, but there are blinds by F$F FOX Shutter). When connected according to the diagram, all blinds work correctly when controlled from the application. However, when I connect the buttons, the 4 shutters which are relatively close to the switchgear work correctly and the other relays go crazy as if they were constantly getting open/closed signals. It is unlikely that 5 wires are faulty. I've lost my mind and I don't know where to look for a solution, maybe the distance affects the operation of this relay because it is designed to work in a box where there is only a piece of space to the button. Please help and regards.

    Hello

    A fairly common and well-known problem. In SUPLI as well as many other solutions you will probably have the same. The installation is usually laid in the wall in such a way that the phase, neutral and control conductor are run with one 3-core cable. As a result, the capacitance between these wires is already at the level of several nF, which causes current leakage. Due to the size of the back-up devices and the limited potential for loss power, the inputs are implemented as voltage inputs. This makes the inputs very sensitive to such situations. The easiest way is to add a capacitor in parallel for the mains voltage between the input and the L or N signal, depending on which level the input is triggered from. A similar situation often occurs with led bulbs and buttons in a staircase configuration. There, too, it is sometimes necessary to add such a capacitor in parallel to the bulb to neutralise its glow. Use a mains voltage capacitor of a dozen or so nF (in the range of about 20 - 150 nF) and you will forget about the problem.

Topic summary

✨ The discussion revolves around connecting a FOX Shutter module to a wall switch, focusing on the correct wiring and functionality. The user describes their current wiring setup, including connections for shutter control and power supply. They seek clarification on how to connect the wall switch, particularly regarding the L connection. Responses indicate that the neutral (N) can be sourced from various points without issue, and the switch's behavior is influenced by the module's software, which allows for one-click operation for full travel of the blinds. However, issues arise with unintended functionality, such as the blinds moving continuously with a single click. Additional concerns about wiring distances and potential current leakage due to capacitance in the installation are also discussed, with suggestions for using capacitors to mitigate these effects.

FAQ

TL;DR: Long switch runs add several nF capacitance that can ghost‑trigger inputs; "Use a mains‑rated capacitor (20–150 nF)" to stop it. This FAQ explains how to wire the wall switch, why S1/S2 show voltage at idle, and how to fix direction/auto‑run quirks. [Elektroda, Drako1988, post #20456351]

Why it matters: It helps homeowners and installers wire FOX Shutter switches correctly and eliminate false triggers or reversed directions.

Quick Facts

How do I wire a wall switch to the FOX Shutters S1/S2?

Connect the switch common to Neutral. Connect the two switch outputs to S1 and S2. Do not feed Live to the switch common. The controller reads Neutral applied to S1 or S2 as a command. After wiring, test Up and Down from the wall switch. [Elektroda, starob, post #19822639]

Which FOX Shutter terminals go to motor and power?

Terminals 1–2 connect to the motor’s two direction leads. Terminal 3 is Neutral. Terminal 4 is Live. Terminal 5 is S2, and 6 is S1. Up/Down assignment depends on which motor lead you place on 1 versus 2. [Elektroda, kannill112, post #19821557]

Why do S1 and S2 show voltage even when nothing is pressed?

The inputs are high‑impedance voltage inputs. A neon probe can glow on S1 and S2 even at rest. That indicates sensing current, not an active command. Use a multimeter if you need a quantitative reading. Operation remains normal. [Elektroda, starob, post #19822781]

Can I take Neutral from the module or from the neutral bus?

Yes. You can feed the switch common with Neutral from the module’s N terminal or the neutral block. “N no matter where you get it from.” Ensure it’s the same circuit as the module supply and tighten terminations. [Elektroda, starob, post #19823102]

Is it normal that a short tap runs the blind fully while a long press only moves while held?

Yes. A short tap triggers auto‑run, and a long press moves while you hold it. “This is a property of the controller itself (its software).” There is no user setting to change this in the unit. Practice your tap timing. [Elektroda, starob, post #19823456]

How do I stop mid‑way or tilt slats precisely from the wall switch?

Start with a short tap, then short‑tap again to stop at your position. For slats, note a full tilt takes about 1.3 seconds. Use quick double‑taps to land between positions more precisely. [Elektroda, kannill112, post #19823489]

My Up/Down are reversed after wiring. How do I fix it?

Swap the two direction conductors. Either interchange S1 and S2 at the inputs, or swap the two motor leads on terminals 1 and 2. This will align the wall switch arrows with the actual movement. [Elektroda, kannill112, post #19865050]

Why do my far‑away blinds misbehave once I connect the buttons?

Long parallel runs of phase, neutral, and control wires create several‑nF capacitances. Leakage through that capacitance feeds the sensitive voltage inputs and causes ghost triggers. The result is chatter or spontaneous open/close indications. [Elektroda, Drako1988, post #20456351]

How do I fix long‑cable false triggers on S1/S2?

Add a small mains‑rated capacitor to each input. 1. Identify the input reference (L or N) for your device. 2. Choose about 20–150 nF. 3. Wire the capacitor from each S input to its reference (e.g., S1–N, S2–N), ideally near the controller. “Use a mains voltage capacitor … and you will forget about the problem.” [Elektroda, Drako1988, post #20456351]

Why does my wall switch show voltage on all three terminals?

High‑impedance sensing makes a neon tester glow on the common and both travelers, even at rest. That is expected and not a fault. The shutter only moves when you actually close a switch contact. Use a proper meter for measurements. [Elektroda, starob, post #19822781]

Can I use the FOX Shutter app before wiring the local switch?

Yes. You can configure the controller and operate the blind remotely first. Users often confirm app control works, then connect the wall switch afterward for local control. [Elektroda, kannill112, post #19821557]

Why doesnt wiring the switch common to Live work on FOX Shutter?

This controller’s S inputs detect Neutral, not Live. If you feed the switch common with Live, the inputs appear constantly hot and behave incorrectly. Move the switch common to Neutral and connect travelers to S1 and S2. [Elektroda, starob, post #19822639]

Will a mechanical interlock prevent pressing both directions?

Yes. A shutter switch with a mechanical interlock physically blocks pressing Up and Down together. Using such a switch reduces user error and protects the motor. [Elektroda, kannill112, post #19821557]

What should I use to verify signals on S1/S2 during troubleshooting?

A neon tester will glow at S1/S2 due to sensing currents, even when idle. That glow alone does not indicate an actual command. If you see the glow, the motor will still stay put until you press. [Elektroda, starob, post #19822781]
