*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 which is no coverage for these models (except when an MCC-91 is used with a Rinnai Hydronic Air Handler). See the Warranty Information for more information on the warranty.

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 (52º 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.

Suggested temperatures are

•	Kitchen	120	ºF (49º C)
•	Shower	98 - 110 ºF (37 - 43 ºC)
•	Bath Fill	102	- 110 ºF (39 - 43 ºC)

These temperatures are suggestions only.

A temperature lower than 98 ºF (37 ºC) can be obtained at the tap by mixing with cold water.

To change the temperature scale from Celsius to Fahrenheit or vice versa, press and hold the “On/Off” button for 5 seconds while the water heater is OFF.
