Hoval District Heating

Use cases

• Monitor outdoor temperature, flow temperatures and hot water temperatures on a live dashboard for each building.
• Adjust room setpoints for heating circuits HK1 to HK3 remotely without visiting the site.
• Track cumulative thermal energy consumption over time to verify billing or efficiency targets.
• Create an alert when the primary valve position deviates from expected range for more than 15 minutes.
• Compare flow and return temperatures across multiple Hoval district heating stations in a portfolio view.
• Switch heating circuit operating modes remotely to adapt to seasonal or occupancy changes.

Installation

1. 1Install the Hoval Connect Modbus Gateway (article 6049501) and connect it to the Hoval TTE system via the internal CAN bus.
2. 2Configure the Hoval Connect Gateway for Modbus TCP (Ethernet) or Modbus RTU (RS-485), noting the IP address or slave address.
3. 3Wire the ModbusCloud gateway (MCG or MLP series) to the same network segment for Modbus TCP, or connect via RS-485 for Modbus RTU.
4. 4In the ModbusCloud portal, add a new device and select the Hoval District Heating template from the template library.
5. 5Enter the Modbus TCP IP address and port, or the RTU slave address and serial parameters matching the Hoval Connect Gateway configuration.
6. 6Verify that live values for outdoor temperature and flow temperatures appear on the dashboard before completing the installation.
