45 minutesModerateModbus TCP/RTU

What You Need

Ethernet cable or RS-485 adapter

Flowstate edge node

Customer provides:

1
Locate controller
Find the chiller's embedded controller or BMS interface point. Most industrial chillers have Modbus RTU (RS-485) or Modbus TCP.
2
Connect gateway
If Modbus RTU: connect a Modbus-to-TCP gateway (or use the edge node's RS-485 port). If already TCP: connect via Ethernet.

1
Map registers
Key registers: supply water temp, return water temp, compressor status, refrigerant pressure, power consumption, fault codes.
2
Set polling interval
10-30 second polling is typical for HVAC. Faster for energy optimization use cases.

1
Compare with local display
Verify supply and return temperatures match the chiller's built-in display. Check compressor on/off state matches reality.
