Features and Benefits
- Patented full program display on the industry’s largest screen – One screen shows zones with run times, watering days, number of start times and special features such as seasonal adjust, zone grouping and restore program.
- Flow sensor and weather station capable – Connect up to two hard wired flow meters and three additional meters attached to decoders out in the field. K-Rain® Weather Station connects directly to the controller and has the ability to modify run times.
- Rain sensor and rain/freeze sensor ready – Allows automated operation to be controlled by sensor.
- Advanced diagnostics – Provides an interactive fault log to track completed repairs. The display shows on which line a fault occurred as well as the outgoing and incoming signal strength to each decoder to better locate a problem. Ability to display real-time current draw on the mainscreen at all times.
- Full keyboard – Makes naming zones, programs and overall programming simple and intuitive.
- Self-regulating decoders – The decoder will regulate the voltage sent to the coil to minimize the current drawn by each coil – making it more efficient and able to open more solenoids than traditional systems.
- Station delay/overlap and pump pressurization – Permits additional time or dual operation for issues like: well recovery, slow closing valves and water hammer, as well as the ability to set a pump pressurization time for each of 5 separate pump start locations.
- Dual transformer design – Time spent programming an entire system is safe and secure. Separates the midbox and your program from the 2-wire lines.
- Independent wire paths – Two independent separate wire paths in case of lightning strike (2 routes per line or 4 total) allows you to easily eliminate half the system from your trouble shooting. It also means that if there is an issue, half of the system will still be able to function.
