The FT1 & LCD 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 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 with the red & white Dipswitches. This allows factory pre- programing, without even powering the controller, additionally it helps preventing users from changing the values defined by the installer.

The standard power option for this controller is 4 X “C” type alkaline batteries (Which can be purchased anywhere).  It can also be powered by a 12V DC power supply or a small solar panel and a small rechargeable battery. 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. The output can operate a 12V DC latch solenoid.
