Finally a suitable timer for my circulation pump

I have long searched for a suitable timer switch for my heating system (hot water circulation pipe) with many switching times and found here.
20 A and opening day are possible. Genial!
Every hour (except during the night-time reduction) run the pump only for 5 minutes and you have saved a lot of electricity costs.
Operation and programming of the switching points is not a problem even without instructions.

Conclusion after almost 1.5 years Duration:
The thing runs and runs and runs .... just great.
Only to complain about is the accuracy of the clock ... there already about 3-4 min come together until the next summer / winter changeover.
Since no precision timer from me is required, which is only half as bad.

5.5.2012 supplement:
-------------------
Is still running without any problems! Simple Top !!!
But soon's warranty end ...'m curious ;-)

Update 6.1.2013:
----------------
I'm still very pleased with the Zeitschaltuhr.Keine problems or failures ...

I do not know why some people here to head over to a faulty battery / battery-changing break ... When the clock should sometimes require a longer battery life in case of power failure, I would in my case (switch for circulation pump my heating system) rather worry about that my heater stops running during a power outage and we sit in the cold. :-)))

On the subject of use without instructions:
Although the keys are labeled on "English": rumspielen After 1-2min, everyone understands the principle of programming the switching points ... because no one needs to study for.

Update 06/01/2014:
----------------
It runs and runs and runs ... the only drawback is just as already mentioned the Gangenauigkeit the clock ... but in summer / winter changeover, it will halt corrected.
