THERMOSTAT OPERATION - DIGITAL BOARD
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 entering the heater. It monitors the water temperature and turns the
heater on when it senses that the water temperature is below the set point. It is normal to experience small fluc-
tuations 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 temper-
ature 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 temperature of the pool or spa.
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 lat-
est 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.
