The Easy Set Logic indoor/outdoor sprinkler timer/controller is the logical timer of choice for residential sprinkler systems with up to 12 zones/stations. This timer is engineered for installation in an indoor or outdoor location. It has a locking door with two keys and the display is mounted on a swing panel which allows you to easily access the wiring. It can power a pump start relay and one valve solenoid at the same time. The A, B and C program slots allow you to set up to three unique watering schedules tailored to different types of zones in the yard. Each program has space for four different start times which allows you to create cycle and soak windows that encourage water infiltration into the soil. The Easy Set Logic sprinkler timer will automatically “stack” overlapping runtimes from different programs so that only one solenoid is running at any given time. The manual run feature allows you to run one zone, select zones, or all zones for a specified length of time, which is very convenient for zone testing or supplemental watering. It has a rain delay feature at the timer which allows you to skip watering of zones for a configurable time when Mother Nature is taking care of the watering, and a relay switch for adding an automatic rain and freeze sensor (sold separately). Installation is as simple as mounting the timer on the wall, putting the common wire (typically white wire) in the C terminal and the individual zone wires in each of the numbered station terminals, plugging in the power cord, and setting the schedules. Push wire terminals allow for tool-less insertion and removal of the wires. The recommended standard sprinkler wire for this timer is 18-guage thickness with 5 or 7 strands/wires.
