user to select the mode of operation, adjust the set-
point temperature, configure the heater controls and
access diagnostic information. The LCD display win-
dow indicates the mode (OFF, SPA, POOL, MANUAL,

play to remain energized and to continue showing the
actual water temperature.
POOL and SPA Modes
If the heater is in POOL or SPA mode, the mode, day
of week and time are displayed on the top line of the
display. The current water temperature, desired water
temperature (SETPOINT), and current status are
shown alternating on the lower line of the display. The
temperature SETPOINT can be adjusted using the UP
or DOWN buttons.
In POOL and SPA modes, the heater will operate to
maintain the desired water setpoint temperature, turn-
ing the heater on when the temperature falls below the
setpoint and turning the heater off when setpoint tem-
perature is reached. Filter pump, motorized valve,
auxiliary outputs and heating operation will operate
according to INSTALLER SETUP MODE settings (See
page 36).
MANUAL OVERRIDE
MANUAL OVERRIDE mode allows manual operation
of controller functions for up to 24 hours. The user
