Digital Controller Operation

The preprogrammed digital controller is mounted through the bezel on the enclosure door. The digital
controller will be powered but the bottom display will read OFF until water is flowing through the heater.
The bottom display will then display the setpoint temperature (See Digital Controller Operation section for
more information).
Refer to table and drawings below for instructions to change the desired set
point temperature of the controller.
