• Shower 98º - 110º F (37º - 43º C)
• Bath Fill 102º - 110º F (39º - 43º C)
These temperatures are suggestions only.
A temperature lower than 98º F (37º C) can be
obtained at the tap by mixing with cold water.

Fahrenheit or vice versa, press and hold the “On/Off”
button for 5 seconds while the water heater is OFF.
Temperature Options Without a Temperature Controller
The default temperature setting for this appliance installed without a temperature controller is 120º F (49º C). If
desired, the temperature setting can be changed to 140º F (60º C) by adjustment of a dip switch.
In the SW1 bank of 8 dip switches, set dip switch 5 to ON to obtain 140º F (60º C) water temperature setting. Set
dip switch 5 to OFF (default) to obtain 120º F (49º C) water temperature setting.
If a temperature controller is installed, then dip switch 5 has no effect on temperature settings.
WARNING
DO NOT adjust the other dip
switches unless specifically
instructed to do so.

The MCC-91 controller is intended for commercial and hydronic
applications only. If an MCC-91 controller is used in a residential
dwelling for a hydronics application, a mixing valve must also be
installed to limit the potable hot water temperature to a safe
temperature. Water temperatures over 125º F (51º C) can cause severe
burns or scalding. Refer to the Danger Alert on water temperatures.
Rinnai shall not, in any event, be liable for damages resulting from such
misuse or misapplication.
** MCC-91 Temperature Controller
These settings require the MCC-91 controller. When the MCC-91
controller is connected, these higher temperatures are available on all
controller models in the system. Use of an MCC-91 controller in a
residential dwelling will reduce the warranty coverage to that of a
commercial warranty application.
* Re-setting the Maximum Temperature
These units have a default maximum temperature of 120º F (49º C) and
an option to increase the maximum temperature to 140 ºF (60 ºC).
Temperature settings from 125-140 ºF (52-60 ºC) are available by
setting dip switch 6 to ON in the SW1 bank of 8 dip switches.
