The different modules are 20/30 outputs.
The outputs can operate a 12V DC latch solenoids or 24V AC solenoids, depending if it is a DC or AC version.
It includes a robust and accurate embedded differential pressure sensor, which can survive a pressure of up to 18 bars. Optionally an external mechanical DP sensor can be used. The FILTRON 20-30 also allows connecting an external pressure sensor (Also called Presostat), and thus preventing the controller from performing unnecessary backflush cycles when there is no irrigation. The backflush process can be triggered by time, by DP or both. The controller has a big customized LCD screen which shows all the backflush parameters, actual status, actual DP value and backflush statistics.
Programming is done easily in two ways:
- Standard - Using the LCD screen and the 4 keys.
- Optional - With the Bluebits smartphone App. The App communicates with the controller using a BLE (Bluetooth low energy) transmitter. This allows programing the FILTRON 20-30 from up to 10 meters away.
The standard power option for the DC version is 4 X “D” type alkaline batteries (Which can be purchased anywhere). The DC version can also be powered by a 12V DC power supply or a small solar panel and a small rechargeable battery. The standard power option for the AC version is the internal 110V AC / 220V AC to 24V AC transformer. The controller has an external manual backflush button, to quickly start / stop a backflush process without even opening the box. If there is a problem of continuous backflush cycles, the controller will detect it and switch to backflush by time only. The controller also alerts in case of a low battery situation.
