In this article, we largely focus on the electrical installation of external blinds. We summarize the differences between the wiring of blinds and screen roller shutters in the conclusion<\/a>.<\/p>\n <\/section>\n\n\n

\n \n

The way the motor is controlled is crucial for the wiring<\/h2>\n <\/section>\n\n\n
\n \n

There are three basic types of motor wiring in terms of preparation:<\/p>\n <\/section>\n\n\n

\n \n
    \n
  1. \u201cConventional motor\u201d controlled by a button on the wall.<\/strong> The motor has its own cable with two wires (blue \u201cphase wire\u201d and yellow-green \u201cground wire\u201d) and 2\u2011phase cores. When one half of the button is pressed and held, current flows into one core, the motor turns upwards and pulls the blind. The other half of the button lets current into the other core and turns the motor in the opposite direction. That\u2019s all the motor can do.<\/li>\n\n\n\n
  2. \u201cConventional motor\u201d with relay.<\/strong> Thanks to the relay, there is no need to hold the button the whole time until the roller blinds are in the end position. Simply hold the button for about 2 seconds and the motor will drive the blind to the end position. Thanks to the relay, you can also connect sensors and central controls to the motor. You can get a relay for a basic motor for an extra cost comparable to that of a \u201csmart motor\u201d.<\/li>\n\n\n\n
  3. \u201cSmart motor\u201d for remote control.<\/strong> It\u2019s even easier to prepare for wiring, because you don\u2019t have to prepare the boxes for the buttons or the buttons themselves at all. The cable is run through straight into the motor. It also provides greater user convenience because you can control it with a remote from anywhere, with your phone, or with preset modes within a smart home. Beforehand, you have to be aware that manufacturers supply <\/strong>them with their own remote control buttons<\/strong>, which are often designer-made and won\u2019t combine with other switches (from a light, for example) in the box.<\/li>\n<\/ol>\n <\/section>\n\n\n
    \n \n

    \u201cFor the first and third options, you can use the same supply cable as for the lights \u2013 <\/em><\/em>CYKY 3C \u00d7 1.5<\/strong>.<\/em> Only if you want to add sensors to the external blinds connected to a conventional motor and feed them from the switchboard for the buttons do you have to go for a 5C \u00d7 1.5 cable,\u201d<\/em> says Jan Musil.<\/p>\n <\/section>\n\n\n

    Running cables from the power supply to the window<\/h2>\n <\/section>\n\n\n
    \n \n

    So that you don\u2019t have to run a cable from the switchboard to each window, you can create junctions<\/strong> and run electricity from one source to all the blinds.<\/p>\n <\/section>\n\n\n

    \n \n

    If you have a \u201cconventional\u201d motor, the button automatically becomes a junction. The KPR 68 box<\/strong> (with extended depth) is ideal for hole sawing. If you are renovating and do not want to chisel into the wall, you can use a wall-mount box on the plaster. With \u201csmart\u201d motors without buttons, the junctions are created only at the blind.<\/p>\n <\/section>\n\n\n

    \n \n

    From the junctions, or buttons, you run the cable further to the motor. In this connection, you need to replace the CYKY 3C \u00d7 1.5 cable with CYSY 4C \u00d7 0.75 soft cable<\/strong>.<\/p>\n <\/section>\n\n\n

    It doesn\u2019t matter which way the supply cable to the motor runs, it depends on the electrician and the possibilities of the building.<\/p>\n <\/section>\n\n\n
