By pressing the Select key, the Pool Target is shown and the text TARGET on the display. This is the pool temperature set point.

By pressing the Select key again, the Boiler Inlet Temperature is shown, indicated by the text Boil In. This is the temperature of the water going into the pool heater. Note that it is different than the temperature of the water coming from the pool.

By pressing the Select key again, the Boiler Outlet Temperature is shown, indicated by the text Boil Out. This is the temperature of the water coming out of the pool heater, before it is mixed with the water from the pool.

By pressing the key Select again, the Boiler Rise is shown, indicated by the text Boil ΔT. This is the difference between the inlet and outlet temperatures at the pool heater.

If the pool supply sensor has been installed and connected, by pressing the Select key, the Pool Supply Temperature is shown, indicated by the text SUP. This will show the actual temperature of the water returning to the pool.

If in the Advance mode (rear dip switch set to “0” position), the Boiler On hours will be displayed, indicated by the text BOIL ON in the display. This is the total number of hours the pool heater has been heating the pool. To clear the Boiler On hours press the Up and Down Arrow keys simultaneously. For a detailed explanation of the advance settings, see Appendix B on page 59 of this manual.

By pressing the Select key again, the display returns to the Pool Temperature display.

The default display shows the Pool Target temperature indicated by the arrow pointing to the text POOL on the overlay, and the text TARGET on the display. This is the temperature of the water from the pool at which the pool heater will turn off. The default is 85°F/27°C.

By pressing the Select key again, the Pool Differential temperature is shown, indicated by the arrow pointing to the text POOL on the overlay, and the text DIFF on the display. This is the number of degrees below the Pool Target temperature that the pool temperature must drop before the pool heater will turn on. The default is 4°F/2°C.

By pressing the Select key again, the Temperature Units will be displayed, indicated by the text °F or °C. This is the units in which the temperatures are shown. The default is °F.

By pressing the Select key again, the Pool Target will be shown once more. To return to the View mode, simply stop pressing any buttons for 25 seconds.

Note: The control values programmed into memory will not be lost because of a power failure.
