Hi, there! Thank you for taking interest in our Irritrol RD600-EXT-R 6-station outdoor controller. This controller can't directly be connected to the supply line but comes with a 24-volt 30-amp pluggable transformer which converts the 110-120V-volt power to the recommended power for the controller. If this 24-volt station controller is directly connected to a 110-120-volt power supply, then chances are that it will explode and ruin your controller. You can, however, hardwire the transformer to the power supply to which will, in turn, will feed the controller with the recommended voltage. It is recommended that for hardwiring a transformer, it must be done by qualified personnel. Please take a look at page 15 of this specification sheet for further details. You can also take a look at the Rainbird SST-600out outdoor controller which includes a transformer inside of the weather box. Here is an FAQ for additional details.

Thanks for asking us about the Rain Dial Sprinkler timer. Clicking the dial one click left of top center will let you choose the current day of the week, and then you can pick the days of the week you want it to run by rotating through the days of the week and setting it to "on" or "off" on the days of your choosing.The day you set your timer to start skipping days will be the first day of the skipping Cycle. So if you did not want to water your landscaping until Sunday, you would set it to skip 3 days starting on Thursday. Hope this helps. Thank you and we hope to see you again here at
