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/Off" bu on
for 5 seconds while the water heater is OFF.

* Temperature se ngs from 125‐140 °F (52‐60 °C) are available by se ng 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 op on
(switch 6) to increase the maximum temperature to 140 °F (60 °C).
** 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. Use of an MCC‐91‐2 controller in a
residen al dwelling will reduce the warranty coverage to that of a commercial warranty applica on.
WARNING
These temperatures are sugges ons only:
Alternate Temperature Se ngs
A different range of temperature se ngs is available by se ng switches 2 and 3 of the SW2 dip switch (white
switches) to ON. The table below shows the se ngs 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 compa ble with
Alternate Temperature Se ngs. Alternate Temperature Se ngs are for commercial
applica ons 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 posi on.
