Aux/Air LED
The Aux/Air indicator LED will appear on the touchpad whenever the Aux/Air button is pushed and
conversly will disapear when the button is pushed again. Note: If the spa does not have a load connected
to the controller the LED will still operate as described above.
2. TEMPERATURE CONTROL
The Spa Power controller automatically controls the pump and heater to filter the water and maintain it at the
desired temperature set by the user (see below). The user can leave the system to look after the spa and
know it will be at the correct temperature when ever he or she wants to use it.
2.1 Adjusting Set Temperature
The Spa Power controller gives the user direct control of the pool temperature from the poolside control
panel. Holding down the Up or Down button will adjust the temperature set point as shown on the digital
readout. There is a slight delay before the buttons operate to reduce the risk of accidental adjustment. The
pool temperature will be maintained very close to the set temperature.

Default Display
The display normally shows the temperature set point, unless the optional in pool temperature sensor is fitted
in which case the sensed water temperature is displayed. In either case the temperature set point will be
displayed while being adjusted as describe dabove.
2.2 Non-Default Display Value
The non-default display value (either sensed water temperature
or temperature set point) can be checked if necessary by
pressing the Up &Down buttons simultaneously.
2.3 Heating Mode Selection (24hr circ pump not fitted)
In addition to the temperature setting the user can select the preferred heating mode. The two available
heating modesare...
1. Demand Heating (displayed as Ht.d).This is the default setting in which the pump and heater will come on
automaticallywheneverthetemperaturedropsslightlybelowthesetpoint.
2. FiltrationOnlyHeating(displayedasHt.F).In this mode the pump and heater will come on automatically no
more than once per hour to filter and heat the water. This mode is provided as an option for those who
prefer to limit the natural cycling of the system.
