Novelan Heating & Cooling WPRnet 2.1 SHI

Use cases

• Monitor real-time power consumption and room temperature of a Novelan heat pump on a live cloud dashboard.
• Create alerts when DHW status indicates the hot water tank has not reached setpoint within a defined time window.
• Block heating or cooling circuits remotely during grid curtailment events or high electricity tariff periods.
• Limit compressor electrical input power via the PC limit register to align with PV surplus availability.
• Track long-term energy consumption and compare heating versus cooling runtimes across multiple customer sites.
• Adjust heating mode and level remotely for seasonal changeover without an on-site visit.

Installation

1. 1Activate the Smart Home Interface in the alpha innotec controller menu, following the manufacturer manual (83055400pUK, part 2, pages 45 to 47).
2. 2Connect the ModbusCloud gateway (MCG or MLP series) to the same local network as the Novelan heat pump controller.
3. 3Verify that the heat pump has a valid IP address and that the gateway can reach it on the Modbus TCP default port (502).
4. 4Import the Novelan WPRnet 2.1 SHI template from the ModbusCloud template library and assign the correct IP address of the heat pump.
5. 5Confirm communication by checking that live values such as RBE Temperature and Power Consumption appear on the ModbusCloud dashboard.
6. 6Configure any desired control outputs, alerts, or scheduling rules within your ModbusCloud project.
