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 on changing the desired set point temperature of the
controller.
