Awesome timer-switch...

  1. Of course, german. What is your equivalent in the States?

    Has solved many of my customers' problems. For instance, timer controlled
    lightning in shops (at night) and at my holiday house, in Vori I installed
    an automatic watering system with this very timer and a 3/4" and a 1/2"
    solenoid water valves (and two plug-in relays).

    I've never seen anything quite like it here. Looks like a piece of
    industrial control gear, not like what you'd find in a residence.
     
  3. It's a generic timer, you can use it for whatever you like. For the
    automatic watering system I had to improvise, because the summers are very
    hot here, and the lawn needs watering twice a day, and we don't go there for
    months, and I can't ask the neighbour to do the watering. The solenoid
    valves come up to 2 1/2" IIRC and they're italian.
     
  4. This reminds me of the old joke, in heaven the cooks are french, the lovers
    italian, the policemen english, the engineers german, and everything is run
    by the swiss.
    In hell the cooks are english, the lovers swiss, the policemen german, the
    engineers french, and everything is run bu the italians.

    Well whatever the case, I've never seen anything like it in the US.

    By CB I assume you mean circuit breaker? That depends on the manufacture
    of the panel here, there are 3 or 4 different standards.

    Such DIN rail mount timer/controllers are fairly common. Here's a data sheet for
    an Australian made unit http://www.aicpl.com.au/brochures/rm4tmr.pdf for
    operation from 12V - 48V dc and a range of common ac voltages from 24V - 240V.

    For a dedicated application such as an irrigation controller I think it would be
    far cheaper and more practical to use something like one of the range of
    Irritrol units http://www.toro.com.au/irrigation/irritrol_category.cfm?cat=8
     
  7. Indeed, they are. They're cheap, too. Mine cost 40 euros the single channel
    model, and 43 euros the dual channel, with invoice and wholesale discount.
    I've got one of those,
    http://www.gardena.com/opencms/open...t=PK410&scat=PK41005&prod=4078500182508&bls=0
    But it works only on a 9 V cell (needs a fresh one every year), the previous
    one we had needed servicing every winter, and it's embedded, sealed
    construction meaning I can't service it myself. And a 9V alkaline goes for
    5-6 euros here, meaning that the system with the timer has covered its
    initial expense (and no service as for now, since 2004).The other one (the
    gardena) has been very reliable up tillnow, knock on wood.
