Underhill’s WaterDex is an innovative,
palm-sized remote that adjusts sprinkler runtimes without reprogramming
the irrigation controller. It includes a mini-transmitter with a
200-foot line-of-sight range and micro-receiver that hardwires into the
irrigation controller. By dialing up or down on the WaterDex
transmitter, you can immediately increase or decrease sprinkler runtimes
for any zone in your system – without affecting the programming cycle.
