CAUTION If using a 24 Vac transformer, use an isolated transformer. If sharing the transformer with your
controller or another device, be sure to connect all of the devices with the proper polarity, since most controllers
are earth grounded. Failure to do so could cause a ground loop that could damage the devices.
