Belimo Energy Valve V4 Modbus TCP

Use cases

• Monitor heating and cooling energy totals per zone on a live cloud dashboard for your customer.
• Create an alert when delta-T drops below a threshold, indicating poor heat transfer or bypass flow.
• Log volumetric flow and thermal power over time to identify oversized or undersized distribution circuits.
• Remotely adjust Vmax and Vmin flow limits to optimize system balancing without a site visit.
• Compare supply and return temperatures across multiple Energy Valves to verify hydraulic balance.
• Track cumulative energy consumption per consumer for tenant billing or energy reporting.

Installation

1. 1Connect the Belimo Energy Valve V4 to the local network and ensure it has a valid IP address reachable by the ModbusCloud gateway.
2. 2Set the Modbus TCP unit ID on the Energy Valve V4 using the Belimo Assistant App or the device display, and note the IP address and port (default 502).
3. 3Wire the ModbusCloud gateway (MCG or MLP series) to the same network segment, ensuring it can reach the Energy Valve IP address.
4. 4In the ModbusCloud portal, add a new device connection using the Energy Valve's IP address, TCP port, and unit ID.
5. 5Import the Belimo Energy Valve V4 Modbus TCP template from the ModbusCloud template library and assign it to the device connection.
6. 6Verify that live readings for temperatures, flow, and power appear on the dashboard, and confirm that unit selection registers are set to metric or imperial as required.
