To ensure your Heat Pump integrates smoothly into the HEMS system, please follow the steps below:
Step 1 – Confirm connection methods and interface parameters
The enjoyelec HEMS Controller supports Modbus-RTU communication with Dimplex L1 12TU Heat Pump model. A standard RS485 connection is required to link the two devices.
Please refer to the Dimplex L1 12TU Heat Pump User Manual to identify the exact location of the RS485 interface, verify the factory default parameters, and understand how to modify them if necessary.
Step 2 – Connect the heat pump to the HEMS Controller
Connect the RS485 cable to the corresponding interface on the HEMS Controller based on the heat pump’s port definitions.
(Note: Detailed interface parameters and wiring examples for the HEMS Controller can be found in the examples below or in the specific HEMS User Manual.)
Step 3 – Configure interface parameters in the enjoyelec app
After completing the physical wiring, power on both devices. Open the enjoyelec app to bind the device and enter the communication parameters that match your actual setup.
(For step-by-step app instructions, please refer to the enjoyelec User Manual.)
Once configured, the Dimplex L1 12TU Heat Pump will be fully integrated into the HEMS, enabling you to monitor real-time data and control the device remotely via the app.
Detailed Example: Integrating Model Dimplex L1 12TU
Step 1 – Identification and Verification
NOTE: For the Dimplex L1 12TU model, HEMS controller is connected via the PCO5+ controller of Dimplex. PCO5+ controller requires additional purchase of BMS RS485 serial card, model PCOS004850.
- RS485 serial card installation
1. Remove the "BMS card" placement cover with a screwdriver.
2. Remove the pre-punctured plastic; you get the hole which corresponds to the tree-pole terminal out.
3. Insert the optional card into the corresponding connector, taking care that the card is firmly placed on both plastic supports on the controller case.
4. Close the cover using the screwdriver, making the outside card terminal fit with the punched hole made on the cover.
The communication interface is located on the BMS RS485 serial card. The communication interface on the terminal marked as "+" is RS485A and terminal marked as "–" is RS485B, show in the diagram below:
- Default Baud Rate: 9600
- Default Modbus Address: 2
Step 2 – Physical Wiring
Ensure that the RS485 port parameters on both the heat pump and the HEMS Controller match. For a default baud rate of 9600, refer to the diagram for the corresponding port on the controller:
- Pay close attention to the A and B cable color coding to ensure the wiring sequence on the Controller side matches the Heat pump side perfectly.
- If a different baud rate is required, please refer to the HEMS Controller manual or use the enjoyelec app to adjust the controller's port settings.
- The RS485 interface of Controller Air2 is "A1&B1" or "A2&B2". The Controller Lite is "A1&B1". Show in the diagram below:
Step 3 – App Configuration
With the physical connection established:
1. Select Device: In the enjoyelec app, choose the correct device type, brand (Dimplex), and model.
2. Set Protocol: Define the communication protocol, physical port number, and matching parameters (Baud rate/Address).
3. Establish Connection: Once saved, the Controller will pair with the heat pump. You can then begin data collection and active energy management.
