Perfect for use on large commercial, industrial and residential sites, SiteMaster controls up to 99 zones. User-friendly, this innovative controller offers advanced diagnostics along with easy setup and operation.Along with the ability to run up to 99 zones, the SiteMaster has an extra large 5″ X 3″ display screen with a full keyboard for easy naming and displays watering days, number of start times, number of stations and specialized programming.

• Patented full program display on the industry’s largest screen, providing comprehensive information about zones, run times, watering days, start times, and special features such as seasonal adjust, zone grouping, and program restoration.
• Capable of connecting flow sensors and weather stations: Supports up to two hardwired flow meters and three additional meters connected to decoders in the field. The K-Rain® Weather Station directly connects to the controller, allowing modification of run times based on weather conditions.
• Rain sensor and rain/freeze sensor ready: Enables automated operation to be controlled by sensors, providing enhanced water conservation.
• Advanced diagnostics: Offers an interactive fault log to track completed repairs, displaying the specific line where a fault occurred and the signal strength to each decoder for efficient troubleshooting. Real-time current draw can be viewed on the main screen.
• Full keyboard: Simplifies naming of zones, programs, and overall programming, ensuring an intuitive user experience.

• Station Run Times: Adjustable from 1 second to 9 hours, 59 minutes, and 59 seconds. Supports programs A, B, C, D, E, and F.
• Start Times: Up to 6 start times per program.
• Watering Schedule: Versatile scheduling options including a 7-day calendar (any day of the week), odd or even days, and interval watering up to 31 days.
• Operating Temperature: Suitable for operation in temperatures ranging from 0°F to 140°F (-18°C to 60°C), ensuring reliable performance in various environments.
• Zone Capacity: Supports up to 99 zones, with zone groups limited to 6 zones and 1 master valve/pump start per primary line. Additional zones (A and B) can be added, allowing for a total of 12 zones.
• Pump Start Requirements: Directly wired pump starts require a K-Rain 1520 or 1510 mini coil power relay. Remote pump start relays on the 2-wire path require a K-Rain 3410 Optical Pump Start Relay in conjunction with a K-Rain 1520 or 1510 mini coil power relay.
• Electrical Specifications: Two options for transformers – a 2-Wire transformer with input of 120/240V and max output of 27 VAC 100VA 3.7 AMP, and a Midbox Transformer with input of 120/240V and max output of 24 VAC 40VA 1.71 AMP. The controller is powered by a 2032 Coin Cell battery (included) and can also use a 9V alkaline battery (optional, not included).
• Dimensions: The controller has a height of 11.91″ (30.25 cm), a width of 15.45″ (39.24 cm), and a depth of 6.43″ (16.33 cm), providing a compact and space-saving design.
