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
If the model name on the side of the water heater ends with
“-UC” (ex. “REU-VA2535WD-UC”), then 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.
Units with model names ending in
“-US” have a default maximum temperature of 140 ºF (60 ºC).
