or SPA operation, and to adjust the setpoint temperature.
The LCD display window indicates the mode (OFF, SPA,

Mode Button
The MODE button is used to select POOL or SPA operation.
It also allows the user to turn the heater off electronically,
allowing the LCD to remain energized and to continue
showing the actual water temperature.
Temp Buttons
If the heater is in POOL or SPA mode, the desired water
temperature (SETPOINT) will be displayed and may be
adjusted using the UP or DOWN buttons.

Operation

In the POOL or SPA modes, the actual water temperature
is displayed along with the desired water temperature
(SETPOINT). When the water temperature is above the
setpoint, "Water Temp" will alternate with "No Demand."
When the water temperature is below the setpoint and the
heater is firing, "Water Temp" will alternate with "Heating."
To adjust the setpoint temperature, make sure the control
is in the appropriate mode (POOL or SPA) and push the
UP or DOWN buttons.
By default, the setpoint range is 50-104°F (10-40°C). See
MAX Settings on page 28 to increase the MAX setting,
if necessary.
