Hoval Energy Management

Use cases

• Monitor outdoor temperature, flow temperatures, and COP of Hoval heat pumps on a live cloud dashboard.
• Trigger Smart Grid mode to shift heat pump operation into periods of PV surplus production.
• Create alerts when DHW or buffer tank temperatures drop below expected thresholds for more than 15 minutes.
• Track thermal and electrical energy totals over time to calculate seasonal performance factors.
• Adjust room temperature setpoint offsets for up to three heating circuits based on energy tariff schedules.
• Log operating hours and switching cycles to plan preventive maintenance intervals for heat pump compressors.

Installation

1. 1Connect the Hoval Modbus TCP Gateway to your local network, or wire the Hoval Modbus RTU Gateway to the RS485 port on your ModbusCloud gateway (MCG or MLP series).
2. 2Enable the Modbus interface on the Hoval TopTronic E controller and configure the correct Modbus slave address.
3. 3For Modbus RTU, set the baud rate, parity, and stop bits on both the Hoval gateway and the ModbusCloud gateway to matching values.
4. 4Import the Hoval Energy Management template in the ModbusCloud platform and assign it to your gateway.
5. 5Verify that live readings such as outdoor temperature and heat pump status appear correctly on the ModbusCloud dashboard.
6. 6Test the Smart Grid trigger and confirm that the heat pump acknowledges the switch-on recommendation.
