Product Information
Electronic Mixing Valve 6000 Series 520 Series
The electronic mixing valve is a complete package with advanced mixing control and a self-cleaning feature. It comes with automatic daily ball rotation to scrape away any scale or debris, ensuring smooth operation. The valve has full functionality without the need for a laptop. It offers thermal disinfection programs to control Legionella in the recirculation circuit. All configuration, set points, temperatures, run status, alarms, and data logging functions are available at the user interface. The valve meets the requirements of NSF/ANSI 372-2011 and complies with ASSE 1017, CSA B125.3, UPC, IPC, and Low Lead Laws, and is listed by ICC-ES for use in accordance with the U.S. and Canadian plumbing codes. It also meets the requirements of CSA Z317.1 Special Requirements For Plumbing Installations In Health Care Facilities.
Product Usage Instructions
- Install the electronic mixing valve according to the manufacturer’s instructions.
- Connect the valve to a power source of 24 VAC floating control.
- Adjust the valve’s maximum operating pressure setting temperature range to ensure stable operation and accurate temperature control.
- Connect the relay contacts for flush valves, 2nd thermostat (aquastat), alarm (unsuccessful disinfection cycle), and recirculation pump (disinfection).
- Use the thermal disinfection programs to control Legionella in the recirculation circuit.
- Use calendar-based programs for scheduling.
- Monitor the valve’s configuration, set points, temperatures, run status, alarms, and data logging functions at the user interface without the need for a laptop.
- Replace the valve if it fails to operate properly.
PRODUCT FEATURES
- Market’s highest rated flow capacity: DZR low-lead brass body, full-port ball valve, ¾” to 3” connections, 2.2 to 537 GPM flow rates.
- Full functionality without a laptop: All configuration, set points, temperatures, run status, alarms, and data logging functions are available at the user interface without the need for a laptop.
- Union pipe fittings: ¾” through 2” models have all-union connections for easy maintenance and service without piping modifications.
- Self-cleaning: Automatic daily ball rotation to scrape away any scale or debris, ensuring smooth operation.
- Thermal disinfection programs: Calender-based programs for scheduling thermal disinfection to control Legionella in a recirculation circuit.
- BAS-ready: Integral MODBUS® is standard. Optional MODBUS-BACnetTM gateway for remote access to building automation integration.
Advanced Mixing Control
LEGIOMIX® is an advanced electronic mixing valve with digital control of
temperature for commercial domestic hot water systems. The daily exercise
function keeps the ball valve free of scale build-up to ensure smooth
operation. Rated highest in the market for flow capacity, this twice-
recognized AHR Innovation Awards product also has an industry-exclusive,
calendar-based scheduling program for automatic circuit thermal disinfection.
