Information, organized.
The landscape display groups P1, P2, differential pressure and wash status so key information is easy to find.
F6 · Next-generation backwash controller
Backwashing.
Clearly in control.
Pressure, wash sequencing and local operation,
organized in one clear control panel.
Building on the original sequential-washing logic,
with a new enclosure and planned connectivity for filtration systems.

01 / Designed for the site
Clear at a glance.
Direct at a touch.
A warm-white enclosure with restrained orange accents.
Display, controls and wiring each have their place.
Controls you can feel.
Back, −, +, OK and Settings retain a familiar five-key layout, with gloved operation as a design goal.
Separate areas for maintenance.
Controls and wiring occupy separate compartments. Bottom cable exits leave room for installation, servicing and labels.
02 / Follow every step
An orderly wash sequence.
A clear view of progress.
Open, backwash, close, pause, then move to the next channel.
Progress and a countdown keep each stage visible.
Try the local-control workflow
Your pace.
Your pace.
Your control.
Choose an automatic trigger mode, or manually start and stop a wash-sequence demonstration.
Trigger a wash sequence by the selected pressure difference or time condition, balancing filter condition with scheduled cleaning.

The original device uses physical keys and does not enable touch operation. Browser buttons demonstrate the control logic here; the screen is an illustrative redesign.
03 / Planned new platform
From beside the device
to the wider site.
An ESP32-S3 controller paired with a separate in-house LoRa module is planned.
Clear paths for nearby setup, hotspot updates and local-network management.

Planned connection to a phone's 2.4 GHz Wi-Fi hotspot for firmware updates.
In-house LoRa
Local-network gateway · Web management
A gateway is planned to provide web control and OTA access.
These are development plans for the new platform. LoRa requires a compatible gateway; internet access is provided by that gateway or a phone hotspot. This connectivity-upgrade plan does not include 4G.
