DIGITAL THERMOSTAT CONTROLS

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 tem- perature 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 narrow 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 is not a problem. It will not harm the heater nor interfere with the thermostat’s ability to precisely control the tem- perature of the pool or spa.

THERMOSTAT CONTROL OPERATION

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

Mode Button

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

Temp Buttons

If the heater is in POOL or SPA mode, the desired water temperature (SETPOINT) 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 temper- ature is displayed along with the desired water temper- ature (SETPOINT). If the heater is firing, a flame icon will be visible.

To adjust the setpoint temperature, make sure the con- trol is in the appropriate mode (POOL or SPA) and push the UP or DOWN buttons.

Fault History File

To access the Fault History File, press the Mode but- ton until the display reads OFF. Press both the “UP” and “DOWN” buttons at the same time (5-7 seconds) until the display changes and shows a fault code. The latest fault code will be displayed first. By pressing the “UP” or “DOWN” buttons, a series of faults will be dis- played from the last (highest number) to the first (low- est number). If the buttons are not touched after 5-7 seconds, the display will return to its normal operation.
