After the initial start-up sequence ends, the actual water tem-
perature is displayed. If water temperature is below 38° C (fac-
tory setting) and the spa is set in skimming/heating mode "F1-
F3", the heater will come on. The heater goes off when water
temperature has reached 38° C.
N.B.: it is normal for the heater to turn on after the spa is first
filled because tap water is often very cold.

press button (+). To lower it, press ( – ).
N.B.: The first press of either WARMER ( + ) or COOLER ( - )
button displays the set temperature.
