Connecting Timer Bathroom Fan: Wiring Diagram, Switch Box, and 3-Wire Cable Configuration

Hello. I have a problem with connecting the time fan, I will present in the pictures everything how it looks for me and I am asking for help.
This is the fan I bought:


Here is the diagram in the manual

;

Previously, I had a regular on / off switch connected to the light bulb in the bathroom connected to the contact with two brown wires like this:


Now I let go of a new three-wire cable from this box where there is an on / off switch for the bathroom:



And this is what all the wires in this box with the on / off switch look like:



I have all electrics connected in boxes in sockets, including 3 yellow wires, as you can see, because they are probably from the socket in the bathroom and from the second switch in the bathroom. please help, how should I connect this fan.

Connect the phase and zero to 2 wires and with the third wire you only trigger the timer switch from the bulb switch.

Buddy, if you could, I am asking you exactly which cable to which.

Hello
Buddy, who did this installation to you Electricians, are the wires connected like this now?
It is very simple, but if you don't understand, take someone you know because it may end badly for you. Regards

The electrician has been doing an electrician with a very long internship, thank you for worrying about me, but with the connection, if I find out how to do it, I will not have a problem. I will add that in this socket there are 3 wires, each of them 3zyly yellow, brown and blue. Yellow connected together, blue also and two brown ones for the switch and the 3 connected with the brown one which goes to the switch

Hello So yes, the wire you added connect Yes blue to blue yellow green to brown after the switch (bulb) and brown to brown in front of the switch where the phase is. On the other hand, the fan according to the photo. Regards

On 2 cables, you need to have normal power supply, as in a socket, and connect the 3rd cable to the light switch so that when the light is turned on, the phase appears on this cable.

Blue connect with the three blue ones that are already connected together? Yellow green to brown, or attach it with the brown one that comes in contact? And the brown one to the other brown one for contact?

Hello
Yes, only brown where there is always Phase in the switch.
Regards

I have already checked, I know where it is, tomorrow I will try to install it there and let you know how it went as the conference went, thank you very much for your help.

If everything is well connected, the blue cables are zero and there is no electricity in them.

Well, there is no electricity, so what will it be possible to connect this cable from the fan to them? Blue 0 and the yellow ones?

Do you know why Laskowik did not have light in his cabaret?
Because it had only pluses, and not a single minus
I understand that when you connect a light bulb to just any 2 cables, it always shines in your home?
You need 3 things on this cable
- 0
- PHASE
-RELEASE
I am writing this for the third time, maybe you will finally read it.

Hello
Do as we write to you and don't write anything else yet
Regards

All right good gentlemen take it easy I only asked because I know that this is more or less the case that not every cable has a plus But I like to ask to know more sometimes

Gentlemen, do not forget that the yellow-green wire is reserved only as a protective conductor.
Protective conductor (PE) - an electric conductor for protection against electric shock. It can be a grounding conductor (connecting the main grounding terminal with the grounding electrode) or equipotential bonding (ensuring equalization of electrical potentials of various live parts). Two-color insulation - yellow-green (always).

That's right. So all the deliberations directing the interested person to adapt this cable as the Control cable are rather at odds with standards and safety ...
It turns out that the electrician, when laying the installation, did not take into account that perhaps an additional wire would be needed ... Standard for Polish electricians ... Especially those with long experience.

Thank you for your help, I connected it as my colleague bajer1 wrote and everything works fine

Hello, I would like to dig out the thread in order not to create a new one, because the topic is very similar.
I have a fan with a time-clock function installed in the bathroom, I know the principle of operation and everything is connected correctly.
Plus to plus, zero to zero, the bell switch is on the second plus (the one that gives the impulse). Everything works as it should, after firing the fan, it works as long as the timer is set.
The question is (because there are no comments about it in the manual), can I replace the bell switch with a standard two-pole switch and will it not have a negative impact on the electronics in the fan?
The effect I would like to achieve: I turn on the fan, it starts because it gets a pulse, but the switch stays on. As a result, the fan does not turn off until the current in the 'impulse' wire is cut off. After being turned off with the switch, the fan works from that moment on as long as the timer is set. Is my reasoning correct? Will it work like that and not hurt the electronics? On the contrary, will the fan be damaged by the 'continuous' current on the 'impulse' wire?

Hello, I also have a dilemma and a question like a colleague above, can you install an ordinary switch? And we will not damage the fan or electronics? It is due to aesthetics. Please answer urgently

Hello
The voltage on the trip lead should not damage the electronics at all times.
On this wire, the voltage activates the fan power supply system, a relay or dependent triac, which the manufacturer used after the voltage disappears, the time to switch off is counted down, if the voltage does not disappear, the system will never disconnect the fan.
