NEMA 1 Digital Controller Operation
The pre-programmed digital controller is mounted through the bezel on the enclosure door/cover. The
digital controller will be powered but the display will read OFF until water is flowing through the heater. The
display will then display the setpoint temperature (See appropriate Digital Controller Operation section for
more information).
Refer to table and drawings below for instructions on changing the desired set point temperature of the
controller.
