DIGITAL THERMOSTAT CONTROLS

Notice to owner- Thermostat operation

Your heater is equipped with a microprocessor controlled thermostat that controls the pool or spa temperature by measuring the temperature of the water coming back through the heater. It will then monitor the water temperature and turn the heater back on when it senses that the water temperature is falling below the set point. It is normal to experience small fluctuations in the return water temperature during the operation of the heater. The thermostat is calibrated with a very close tolerance to ensure accuracy of the set temperature. Thus, slight fluctuations in water temperature may cause your heater to cycle on and off frequently. This phenomenon is not a problem. It will not harm the heater nor interfere with its function to precisely control the temperature of the pool or spa.

THERMOSTAT CONTROL OPERATION

The pool heater thermostat on the upper front panel of the heater controls the pool/spa water temperature. This control center contains a mode button, up and down temperature adjustment buttons, and a LCD display.

Mode Button

The MODE button functions as a means to turn the heater off or on in either the pool or spa temperature setting. The LCD display indicates the mode the heater is in and the actual water temperature.

Temp Buttons

If the mode is in POOL or SPA, the desired pool or spa temperature will also be displayed and may be changed using the UP or DOWN buttons. A manual toggle switch is also provided right below the MODE button to allow the heater to be turned off.

Operation

In the POOL or SPA modes, the actual water temperature is displayed along with the desired pool or spa temperature. If the heater is firing, a flame icon will be visible.

To adjust the desired pool or spa temperature setting, make sure the control is in the appropriate mode (POOL or SPA) and push the UP or DOWN buttons to get the desired set point temperature.

Set Points

The electronic thermostat cannot be set above selected maximum set points. The maximum default set points are factory set at 104°F for both pool and spa. These can be changed to a higher or lower value to suit your needs, but can never be set above 107°F.

Program Mode Button

To adjust the set point, press the Mode button until the display reads OFF. Remove the four screws holding the control cover on. Swing control panel down so the back side of the board is visible (see page 27). Locate the Program Mode button as show in figure 9481.

Hold this button and use the Mode button to select “Set” on the digital display. You can release the button once “Set” appears. Using the “Up” and “Down” buttons will change the Maximum Temperature Setting. The control can be set for a maximum of 107°F. A separate value can be set for either Pool or Spa by using the Mode button to select Pool or Spa and using the “Up” and “Down” arrows to select the desired Max temp for each. Once this is done reassemble the control panel.

Fahrenheit vs Centigrade

The digital display is capable of displaying Centigrade as well as Fahrenheit temperatures. To change the display follow the instruction above to access the Program Mode Button. Hold this button and use the Mode button to select “F/C” on the digital display. The
