The Hozelock Sensor Plus Controller features a daylight sensor that automatically adjusts your watering schedule to start at sunrise and sunset, with a choice of daily operating schedules. It will automatically change the start times to coincide with sunrise and sunset as the seasons change, providing the user with an autonomous controller that requires minimal maintenance. The watering schedule can be set to operate every day for hot and dry conditions and has adjustable settings to reduce watering down to every 2 days, every 3 days, every 5 days or once a week for plants that require less water. If you need to dispense water outside of the automatic schedule you can use the Water Now button to turn on the water. Press the button to select watering for a 10, 30 or 60 minute duration. Simply press again to cancel the operation for shorter periods. The Sensor Plus Automatic controller has a low battery warning light and charge status LED indicators to keep track of available power, while an onboard failure prevention safety feature detects when the battery levels have dropped to a level that could fail whilst a watering schedule is in progress, ensuring water is not wasted due to battery failure mid-task. The Sensor Plus Controller is a versatile unit that can be used with Garden Sprinklers (up to 10 Bar), low pressure micro irrigation watering (1.5 Bar) or Water Butts (0.1 Bar) due to the unique ball component. It is supplied with a choice of 21mm (1/2" BSP), 26.5mm (3/4" BSP) or 33.3mm (1" BSP) adaptors for connection to most garden taps.
