Rinnai RC98I Temperature Options Without a Temperature Controller, MCC-91 Temperature Controller

Temperature Controller Settings

*Re-setting the Maximum Temperature

These models 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 switch 6 to ON in the SW1 bank of 8 switches.

**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.

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.

A temperature lower than 98º F (37º C) 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.

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 switch.

In the SW1 bank of 8 switches, set switch 5 to ON to obtain 140º F (60º C) water temperature setting. Set switch 5 to OFF (default) to obtain 120º F (49º C) water temperature setting.

If a temperature controller is installed, then switch 5 has no effect on temperature settings.

Setting the Sound Volume (Voice Prompt)

MC-100VPress the “Function” button to adjust the voice prompt volume. The default sound volume is set to Medium. Each subsequent press of the ▲ or ▼ button cycles through the volume levels in the order below.
