For All Systems
Setting Hot Water Temperature
Operation ScreenDisplay Description
• Hot water temperatures shown are approximate and may differ from the actual temperature at the fixture
depending on external factors such as the season and length of piping in the system.
• When low temperatures are set (for washing dishes, etc.), if the incoming water temperature is already quite
high, it may be difficult to ensure the outgoing water temperature is as per the setting.
• Please check the temperature displayed before using any hot water.
Be especially careful using hot water after the set temperature has been changed.
• When the hot water temperature is adjusted using thermostat controlled water mixing valves, set the
temperature on the remote controller approximately 20°F (10°C) higher than the required temperature to
ensure the appropriate fixture temperature.
If xtures incorporate mixing valves, set the temperature higher than usual.
*
For applications that occasionally require a higher temperature setting, locate the remote controller in a convenient location.
* Consult local codes for minimum operating temperatures.
Note : An error code will be displayed when this water heater detects scale build-up in the heat exchanger.
The error code may be more frequently displayed when the unit is set to a high temperature. (125°F or higher)
Noritz recommends that water temperature is set as low as possible to prevent scale build-up in the heat exchanger.
