Rinnai Circ-Logic recirculaon technology allows users to set
recirculaon paerns that coincide with their hot water usage
paerns. Hot water is available when needed, without the expense
of circulang it during mes of inacvity. Two recirculaon modes
are available:
• Dedicated Mode - With a dedicated return line, the integrated
pump recirculates water from the tankless water heater through
the return line and back to the heater.
• Crossover Mode - In applicaons where a dedicated return line is
not available or is dicult to install, Circ-Logic technology allows
for the simple installaon of a Thermal Bypass Valve (included
with purchase) at the xture farthest away from the water heater.
Thermal Bypass Valve
• Compact Design to Save Space
• Wi-Fi Technology for Remote Monitoring and Management
• Simple Gas Conversion
