My current Orbit timer has a 24vac 300mA transformer. If I need to replace the transformer can I use the transformer from my previous non-Orbit timer? The old transformer is a Class 2 24vac 20VA transformer. I will most likely have to order a replacement transformer due to my local.
I went ahead and switch out the 300mA transformer with the 20VA transformer. It powered up my timer okay, but as soon as I input the command to turn on a watering station, the fuse blew. I replaced the fuse and the same thing happened when turning on that same station. Was too much power going into the timer? Or do you think I have a wiring problem?
Orbit technical support email stated, "As long as the transformer is 24-30 volts and 300-750mA it will work." I went to my local Radio Shack to get a transformer but they do not stock them, however they said the extra powerful transformer (20VA) should not harm my system. What do you think??
