It's not always as simple as previously described ..

Very positive for a quick installation (there were indeed already called 10 minutes) is a deep flush-mounted box.

Furthermore, it is decisive whether the shutters were already operated with an electronic timer or by mechanical paddle shifts.

Had previously been an electronic circuit, so you can replace them relatively quickly through the items assessed here. The arrangement of the connections and the depth of the component you need in accordance with long cables. This length should be present rule ID.

Something different is when previously operated the shutters with so-called. Paddle shifts. In this type of circuit, the (current) fiber cable is split to the UP and DOWN rockers and passed each on the operating the rocker to the shutter motor. It is the neutral wire is not required and therefore may not (immediately) available.

For this switch you also need a neutral conductor.

At the time switch the conductor cable, the neutral conductor and the two ports for up and down are connected. Thus, one needs behind the device also place in the UP box for these 4 cable.

After connecting the cable 4 is pressed, the device in the -vorher eingebauten- holding frame. Here, raced up and down or left and right plastic prongs against each other. (A good idea installation)

The line programming the clock has already been described in previous reviews. This is relatively fast.

The display is relatively small for programming. The best you can see the numbers and symbols when you directly from the front (ie at the same level) looks at the display.

Setting the time and the UP and DOWN times then goes relatively quickly.

For the rich features of this device, I rate this timer as inexpensive.
