Temperatures Available with a Controller
The water heater can deliver water at only one temperature setting at a time. 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/Off" button
for 5 seconds while the water heater is OFF.

* Temperature settings from 125-140 °F (52-60 °C) are available by setting switch 6 to ON in the SW1 Dip
switch (tan switches). These models have a default maximum temperature of 120° F (49° C) and an option
(switch 6) to increase the maximum temperature to 140 °F (60 °C).
** These settings 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. Use of an MCC-91-2 controller in a
residential dwelling will reduce the warranty coverage to that of a commercial warranty application.
WARNING
These temperatures are suggestions only:
Alternate Temperature Settings
A different range of temperature settings is available by setting switches 2 and 3 of the SW2 dip switch (white
switches) to ON. The table below shows the settings available with the MC-91-2 and MCC-91-2 controller.

MC-91-1, MCC-91-1, MC-100V-1, and BC-100V-1 controllers are not compatible with
Alternate Temperature Settings. Alternate Temperature Settings are for commercial
applications only.
DO NOT use the MC-91-1, MCC-91-1, MC-100V-1, or BC-100V-1 controllers when dip
switches 2 and 3 (white switches) are in the ON position.
