I had long been looking for a replacement remote control my garage door. The original manufacturer WECLA there is probably no longer for 15 years. The drive (24 V DC) itself is still mechanically sound. It would have been too cumbersome to replace the entire drive and certainly more expensive. I just had to make a small change (separating an interconnect and soldering a wire jumper) because I needed two potential-free relay contacts. The reconstruction was finished in about 10 minutes. The installation was carried out in parallel to an existing button. Since the Torantieb works with new remote control properly. The remote control even has a greater range than the original. Conclusion: full purchase recommendation, technically sound, safe and cost-effective
