Connect the hood to the bathroom through the switch correctly, consider the errors and schemes

Lack of standard extraction in the toilet or bathroom is characteristic of the huge number of apartments. And in order to improve provetrivaemost such premises, many use forced draft. In this article I will talk about the basic rules and mistakes when installing the hood in the toilet or bathroom.

How to check the hood

Before proceeding to install the fan, make sure that the air flow in the exhaust shaft is present. To do this, take a conventional spark, ignite it and bring to the grid if the flame will deviate towards the hood, the air current is present, if not, the extractor is faulty.

Alternatively you can take an ordinary sheet of paper and close their hood, and then release the paper and if it falls, the air current is absent.

If you find that the ventilation system is not working, you should file a complaint with your the management company and, if working, but not enough, it is possible to put an exhaust fan, which we loans.

Options extraction connection

So, first let's find out what options are possible at all:

1. Connecting the product through a motion sensor or sensor door opening.

2. Connection through the humidity sensor.

3. Connecting directly through the light bulb.

4. Connecting via a switch.

This is all possible connectivity options, let's start with the wrong options.

It does not need to be connected

In the first three methods described above have a number of disadvantages that you may encounter, such as:

Let's consider the case of a defined humidity sensors or monitoring air quality.

Agree, when you take a bath, the indoor humidity is very high and in this case, hood will operate without interruption, and it is not very convenient, because you will feel a constant draft.

Just inconvenient sensor to open the door, imagine that you have installed such a device in my closet, in the majority of the time limit for sensor operation is 5 minutes, and if you linger in the toilet? Open and close the door? In my opinion it is not very convenient, especially if you will be away.

Mounting conventional motion sensor inside the bathroom (like any other switch) is disabled, as it is a switching device, and according to the SAE:

Extraction socket directly through the lamp holder it is the least expensive, but it too is not correct, since the hood will operate smoothly while the light will illuminate. And if the toilet is still somehow acceptable (although once you turn off the light the fan stops and the room not ventilate properly), the connection in the bath is unacceptably due to the formation of drafts during reception bath.

So, it turns out the only true and correct connection is drawing through the switch, we consider it in detail.

drawing connection through switch circuits consider

As we consider the extraction fan with built-in timer, for example, a model of how ERA.

This hood allows you to switch between the two modes by rearranging jumpers.

When working in wc (jumper in the upper position) hood will switch on as soon as the light is turned on and run for some time after switching off the lighting.

If the jumper is installed in the lower-position (bathroom), the extractor switched on only after when the light is turned off (provided that it is burnt through at least 1.5 minutes).

Just such a connection can be realized through a double switch: where one key will be responsible for lighting, and the second for turning on and off the fan

In this case, wiring diagram is as follows:

Important. Note that the extract is fed to such two phases, one directly, bypassing the switch through the second switch, and the working zero. If you have a three-core cable is wired, then this extract should pave chetryrehzhilny wire: L1, L2, N, PE.

conclusion

So, we looked at how not to and how to connect the hood to the bathroom and toilet. If the article was useful to you, then put his finger up and thank you for your attention!
