The CCR2+ optimizes thermal disinfection in hot water systems with temperature registration and monitoring. It can be used independently for temperature registration. Thermal disinfection is effective for bacteria pasteurisation (Legionella pnemophila). Optimizing this process reduces energy consumption and disinfection time, lowering bacterial contamination risks. Disinfection temperatures range from 50 °C to 78 °C; time is adjusted based on Brundrett recommendations and cannot be altered beyond set limits.The CCR2+ features LED status indicators, a built-in Web-Server App, Wi-Fi, LAN port, and memory for temperature data storage. Users can adjust the storage rate and export data to Excel. It controls multiple risers with thermoactuators and PT1000 sensors. One unit manages 20 risers and an S0 sensor for disinfection initiation. Additional features include alarm output, pump protection, and system expansion. Power supply is ~24 V (DC), 50 Hz. Installation is on a standard DIN relay.
