Toshiba's facility team in Bangalore had a working chiller plant — three chillers, three pumps, three valves — but no central window to watch it, no graphics to understand it, no way to control it remotely, and no staging logic to manage load automatically. EnSmart connected to their existing controller over Modbus, deployed Smart Nova above it, built live graphics, and gave the operator a single screen to monitor, control, and automatically stage the entire plant. Start to finish: one week.
Existing controller. Smart Nova on top. Stage Up, Stage Down, and full visibility — delivered in seven days.
Download the Full Case Study →Ravi is the facility manager at Toshiba's Bangalore office. The chiller plant has been running for years. Three chillers cool the building. Three pumps push chilled water through the floors. Three valves balance the flow. There is a controller sitting in the panel room that talks to all of it. But Ravi has no graphics screen, no trends, no energy report, and no way to start or stop equipment from his desk. Worse — nobody has told the plant what to do when the load changes. All three chillers run together whether the building is full or empty. Nobody stages them up when demand rises. Nobody stages them down when demand drops. The controller does not know how to do that. Every morning Ravi walks to the plant room, reads the panel, and writes numbers in a register. If something trips at night, the guard calls him. He drives in. That is the system.
The result:
Inside the full case study, you'll see:
| Year | Milestone |
|---|---|
| Day 1 | Site survey: existing controller identified, Modbus register map obtained from panel documentation, equipment list confirmed — 3 chillers, 3 pumps, 3 valves |
| Day 2 | Modbus communication established between Smart Nova and the existing controller, all registers verified live |
| Day 3–4 | Chiller plant graphics designed and built in Smart Nova — chillers, pumps, valves, piping, temperature points, status labels |
| Day 5 | Stage Up and Stage Down logic configured in Smart Nova, control write registers mapped and tested — CHW Enable, EN CHE Enable, individual equipment start/stop verified from screen |
| Day 6 | Energy report module configured, trend logging enabled, alarm thresholds set |
| Day 7 | Operator handover and training, staging logic demonstrated live, system signed off, Toshiba facility team live on Smart Nova |

They are running blind because the software layer was never part of the original project scope, or the licence lapsed, or the integrator left and nobody followed up. And most chiller plants are not running inefficiently because the equipment is bad — they are running inefficiently because nobody added staging logic above the controller. Toshiba Bangalore had a well-maintained chiller plant. The controller was doing its job. What was missing was visibility and intelligence — a screen that showed what was happening, and a brain that decided what should happen next. Smart Nova provided both in one week, above the existing controller, without replacing a single piece of hardware. That is what integration-first BMS delivery looks like in practice.
