- Irritrol RainDial External Key
In addition to the numerous upgrades built into this popular, long-standing controller, the optional CLIMATE LOGIC® Wireless Weather Sensing System makes the Rain Dial-R a "smart" controller on the cutting edge of water management. When governed by Climate Logic, the Rain Dial-R will automatically water more on warm or hot days and less on cooler days. Applying the right amount of water to maintain a healthy landscape, the Rain Dial-R and weather-based Climate Logic Weather System seriously reduce overwatering and its expense.
