Hi all, I had an interesting issue last week. One of my clients was having some issues with his lights and fans behaving strange. I investigated and found that the switch that was supposed to switch on some lights was switching a fan in another room. A DLT was supposed to switch lights and have a label with ?Lights? on it was switching the same fan as above and was displaying the fan speed. When I opened the units in toolkit, the programming was setup to switch the lights, not the fan. I resaved the programming and they switched the correct lights again. The DLT needed a full reset and reload of the program to get the labels sorted. We found an exploded frog in the main switch board that touched one of the phases and ground. Frog is now removed and the electrician is replacing the breaker. I got a picture of the frog, looks cool. Anyone has seen a problem like this before? Cheers, Roeland
