120 VAC Input 25.5 VAC Output 4 Stations Indoor Modular 10.7" x 4.4" x 7.7" ESP-SMTe Series Smart Modular Control System | RBLESP4SMTEI

Key Features

• Instant rainfall shut-off and usable measurement - A smart controller should be smart enough to account for rainfall, In fact, most smart controllers simply suspend irrigation when it rains, without accurately measuring rainfall, by comparison, the ESP-SM
• The proven accuracy of weather-based scheduling - In designing the ESP-SMTe, we've simply reduced the cost and complexity of the weather-based control systems we began pioneering for golf courses over 25 years ago, drawing on the industry-leading precisio
• Expandable modular design - The Rain Bird ESP-SMTe can grow with landscape, easily expanding from 4 stations up to 22 stations with the addition of optional hot-swappable expansion modules
• Zone-specific water calculations - Different plants have different watering requirements, that's why the ESP-SMTe customizes each zone's irrigation schedule, it factors in location, soil type, landscape slope, plant type/density, sun exposure, sprinkler t
• Rain Bird recommends that the maximum irrigation zone cycle time be less than the time required for runoff to begin and that there be adequate soak time before the next irrigation cycle of that same zone begins again
• Surge Protection: primary input side has (2) built-in MOV's (metal oxide varistor) to protect circuitry, output side has(2) built-in MOV's for each valve station
• Power back-up: Lithium coin-cell battery maintains time and date while non-volatile memory maintains the schedule
• Multi-valve station capacity: Up to two 24 VAC, 7 VA solenoid valves per station plus a master valve
• English/Spanish button easily switches the display text between languages
• Weather sensor sends rainfall and temperature data to the controller
