Bösch MOZART/KLIMT-RW60 Heating & Cooling

Use cases

• Monitor supply and backflow temperatures, outdoor temperature, and COP values on a live cloud dashboard.
• Create alerts when a fault state is detected on the heat pump to reduce response time for service calls.
• Track compressor, fan, and pump operating hours to plan preventive maintenance intervals.
• Adjust PV mode target temperatures for heating and hot water remotely when PV surplus conditions change.
• Log thermal and electrical power over time to calculate seasonal performance factors for energy reporting.
• Compare COP values across heating, cooling, and hot water modes to optimize system configuration.

Installation

1. 1Locate the Interface-Module on the RW60 controller; its position varies depending on the specific MOZART or KLIMT model.
2. 2For Modbus RTU, connect the RS-485 A and B lines plus GND from the ModbusCloud gateway to the Interface-Module terminals.
3. 3For Modbus TCP, connect the RW60 controller to the local Ethernet network using a standard network cable and ensure the gateway can reach the heat pump IP address.
4. 4Contact Bösch service to activate the Modbus RTU or Modbus TCP protocol on the RW60 controller before commissioning.
5. 5Set the Modbus RTU baud rate on the ModbusCloud gateway to 38400 and configure the correct slave address as assigned to the heat pump.
6. 6Import the Bösch MOZART/KLIMT-RW60 template in the ModbusCloud platform and verify that all data points are reading correctly.
