Description Regulate Flood and Drain Times with a Single Second of Accuracy. Day and Night The Flood and Drain Timer switches the pump to your aquaponic system on and off as required, allowing you to tailor to your plants exact needs. Just choose the length of each flooding time (impulse), then select the duration of the Draining time (interval), the timer is set and then will automatically repeat the set cycle. You can even choose different settings for daytime and night-time – the photocell sensor will automatically switch the unit to the right schedule each season according to your desired flood and drain cycle. Separate daytime and night-time flood and drain cycle modes 4.0 metre light sensor to automatically switch between day and night settings Plug and play interface Simple analogue control knobs for settings Great for drippers, flood & drain, aeroponics, hydroponics, aquaculture, etc. 10amp to handle decent size water pumps 3 pin UK plug and socket Moisture proof Suitable for outdoor in a protected cabinet. Suitable for commercial application Contains: 1 x timer unit with 4.0 metre light sensor and 1.3 metre power cable Ampage: 10 amp Voltage: 230v How this Unit works: This water cycle timer is designed to power the water pump to your hydroponics / watering system. Standard domestic Segmented Timers typically switch equipment on or off in 15 minute increments only. When you want to control efficiently a flood and drain cycle you're most probably going to need more control than standard timers can offer. This Water Cycle Timer allows you to select the length of the pumping cycle itself and also the length of the interval (off time) between each cycle. Pumps can be switched on for durations of between 1 second and 20 minutes, giving you plenty of flexibility to tailor feeding times exactly to your plants' needs. The interval dial decides the length of time that the pump is switched off for before it turns on again for another cycle. This gap can be set between 1 second and 16 hours, giving you plenty of scope to time your feedings as frequently or as infrequently as you need to. There are four dials in total: cycle time & interval (daytime), cycle time & interval (night-time). You can choose different settings for day and night and the controller will automatically switch itself to the correct schedule by detecting light levels with its 4.0 metre long light sensor.
