Controls iDM heat pumps via Modbus TCP using Navigator 2.0
Overview
This template connects to iDM heat pumps equipped with Navigator 2.0 control via Modbus TCP over Ethernet. It enables monitoring and control of heat pump operation directly from the ModbusCloud platform. No additional hardware modules are required on the heat pump side.

Use cases
Monitor heat pump supply and return temperatures on a live cloud dashboard for remote diagnostics.
Create an alert when the compressor runs continuously for longer than a defined threshold.
Log heating and hot water setpoints over time to verify correct scheduling and comfort levels.
Track coefficient of performance indicators by combining temperature and runtime data in trend charts.
Adjust operating mode or setpoint values remotely without requiring an on-site visit.
Provide end customers with a shared dashboard showing current heat pump status and energy usage.
Installation
1Connect the iDM heat pump with Navigator 2.0 control to the local Ethernet network using a standard RJ45 cable.
2Verify that Modbus TCP communication is active on the Navigator 2.0 controller and note the IP address, TCP port, and unit ID.
3Install the ModbusCloud gateway (MCG or MLP series) on the same local network and ensure it can reach the heat pump IP address.
4Import the iDM Heat Pump template in the ModbusCloud platform and assign it to the gateway.
5Configure the connection settings in the template (IP address, port, unit ID) to match the heat pump network configuration.
6Confirm that register values appear correctly on the ModbusCloud dashboard and set up any desired alerts or trend logs.
