Immature and prone to failure!

I want's brief: not recommended!
As these actuators on the noted arrived I was thrilled, because it gets the usual local control. Unfortunately, I got fairly quickly to the actuators problems.
- That the frame is flabby and too fat is been already mentioned several times here.
- The connections are quite unfavorable and burden the terminals by the connected cables when installed quite strong.
- The construction is not sufficiently protected against Störmpulse. Ie that the glitches in the actuator to bring the engines the microprocessor to crash. One way the actuator is missing trigger a reset automatically or manually, at least.
Electric motors produce after all faults, just off the a /. Even with filters in the supply lines for shutters motor ranging pulses partially pending at these actuators to crash. I have now again been replaced two of these actuators by the older variant UP. These are much more fail-safe, more of these actuators have been running for 2 years with no problems. As nice as it is with the operator on the actuator, but for motors good for this crap here. Selbt isolating relay may bring no improvement.
One must ensure that the cables are routed shutters as far away from the actuator!
Because of all the trouble, VA. the exchange and the whole Umprogrammiererei there's only one star. If I automate my apartment then have to walk that can not always reset the actuators at the fuse box on the fuses ...
