- Environment: School Campus
- Customer wants to replace control logic on water sprinklers with total on-fly schedules and controls.
- Cannot disturb existing fields to add communication wires.
- May install external antenna on site of main building.
- Of all 8x water zones only 2x are controlled from within the main building.
- The man building already has an expanded BAS with a custom programming and graphic interface.
- The remaining 6x external control points all have no existing communication between them or the main building.
- Wireless communication is possible providing repeater zones can be established.
- Verifying 4 repeater zones are needed around the campus, all 8x zones can now be controlled.
- Main antenna cannot be installed from original placement due to too much grounded metal in surrounding structure.
- Found new place to install main antenna from main building and bridged to existing BAS.
- Using signal strength to maximize signal quality, repeater zones were established across the campus with redundancy and fall back.
- All existing logic in sprinkler zones were replaced and updated with wireless communication.
- Programmed with customers explications to handle updated graphics with multiple zone schedules with pr-programmed setups and overrides.
- All logic can be setup by customer on the fly and left unattended.
- Rain sensors were installed after to stop over watering the grass.
- Customer now has all 8x sprinkler heads that can be fully controlled by them.
- No fields were torn up and the wireless communication is 95% signal at the worst point.
- All communication is setup as a packet transmission with fallback and error checking at hardware level running at a very vast speed, Quicker then the wired controllers.
- The system is expandable when the customer needs it.
- And as a backup all controllers have overrides (HOA) by controllers.
