Tankless water heater must have water connections on the
bottom, and be constructed with NSF 61 listed materials. Direct
heating element to be non-ferrous, cartridge style, designed for
eld replacement. Tankless water heater to utilize a dual PID
algorithm, actively managing power application to real-time system
demand. Integrated ow meter capable of volumes in excess of
30 GPM drives predictive control algorithm. Water heater must be
protected by redundant safeties. Redundant safeties to include
thermo mechanical safety switches, infrared element monitoring
via thermo optical sensors, and dual temperature monitoring via
master control board. Tankless water heater user interface must
have the following capabilities:
• Selectable display including Celsius/Fahrenheit, inlet
temperature, outlet temperature, ow rate, and setpoint
temperature.
• Capable of displaying ow rate in gallons per minute or liters
per minute.
• Diagnostic features to include error and fault code display.
• Control board must maintain error/fault history of 9 events.
• Capable of factory coded temperature setting (max. and min.)
• Capable of rmware upgrades via USB port
• Capable of BMS integration - contact factory
• Compliant with ANSI Z358.1 tepid water without additional
mixing or purge features (inlet temperatures must not exceed
100°F when selecting an EE or EFD option)
