Seng Controller to Mute

On the MC-91-2 to eliminate the beeps when keys are pressed or to turn the beeps back on, press and hold both

the up and down buons unl a beep is heard (approximately 5 seconds).

Locking the Controller

The MC-91-2 controller can be locked by pressing the Priority buon and the up buon together for 5 seconds.

A beep will sound conrming that the controller is locked. The display will alternately show “LOC”, the

temperature seng, and a diagnosc code if one has been acvated. All of the controllers in the system are

also locked.

To unlock the controller press the Priority buon and the up buon together for 5 seconds.

Temperature Opons Without a Temperature Controller

The default temperature seng for this appliance installed without a temperature controller is 120° F (49° C). If

desired, the temperature seng can be changed to 140° F (60° C) by adjustment of a switch.

Set SW 5 in DIPSW 1 to ON to obtain 140° F water temperature seng. Set SW 5 in DIPSW 1 to OFF (default) to

obtain 120° F water temperature seng. If a temperature controller is installed, then SW 5 has no eect on

temperature sengs.

Temperatures Available with a Controller

The water heater can deliver water at only one temperature seng at a me. The available temperatures are

provided below. A temperature lower than 98° F (37° 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/O” buon

for 5 seconds while the water heater is OFF.

These temperatures are suggesons only:

* Temperature sengs from 125-140°F (52-60 °C) are available by seng SW 6 in DIPSW 1 to ON. These

models have a default maximum temperature of 120° F (49° C) and an opon (SW 6 in DIPSW 1) to

increase the maximum temperature to 140 °F (60 °C).

DO NOT adjust the other switches unless specically instructed to do so.

** These sengs require the MCC-91-2 controller. When the MCC-91-2 controller is connected, these higher

temperatures are available on all controller models in the system.

If an MCC-91-2 controller is used in a residenal dwelling for a hydronic applicaon, a mixing valve must

also be installed to limit the potable hot water temperature to a safe temperature. Water temperatures

over 125°F (52°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 resulng from such misues or misapplicaon.
