The RD600, RD900, and RD1200 modules are all described in the same user manual. Is your controller not working the way you expect? The Irritrol RainDial manuals are good, but if the controller is failing, the user manual won’t help. As they fail, the RainDial controller often behaves erratic and becomes intermittent as it begins to fail. If you think your controller may be failing, repairing them is our business; if the manuals and programming tips mentioned below don’t help solve your problem, we would appreciate your business repairing the controller.

Most of the Irritrol Rain Dial controllers operate in the same way. Newer controllers have some additional features but the basic user interface has not changed in years. They’re easy to understand, easy to use, and a large selection dial makes for a friendly user interface. They are excellent timers compared to the competition.
