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 touch the
UP or DOWN keys.
By default, the setpoint range is 50-104°F (10-40°C). See
"Program Menu" on page 31 to increase the MAX
setting, if necessary.

The first screen displayed is the Flame Strength indicator,
which indicates the flame current using a numerical display.
A signal of less than 1.0 μA indicates a weak flame signal
and may require service. Refer to "Troubleshooting" on
page 47 for possible causes and corrections.

order. Run time hours at the moment of the fault are
displayed at the end of line one. The second line of the
display shows the fault message. If there are no faults in
the history buffer, the second line reads "All Faults Clear."
