Key Features
DZR Low-Lead Brass Body
Dezincification-resistant low-lead brass body, compliant with NSF/ANSI/CAN 372 and certified by ICC-ES under file PMG-1360 for lead content in drinking water system components. Sizes 2-1/2" and 3" use AISI 316 stainless steel balls with galvanized carbon steel slip-on flanges.
Programmable Thermal Disinfection
Scheduled high-temperature disinfection cycles help manage Legionella risk in domestic hot water systems, with logged cycle verification.
Integral RS485 Modbus Communication
The controller carries an RS485 serial output running Modbus RTU, addressable on a multipoint bus for setpoint control, alarm reporting and disinfection cycle logging. BACnet connectivity is not integral; it requires the Caleffi 755052 Modbus-to-BACnet gateway, sold separately. Contact Caleffi for the LEGIOMIX register map.
