The SpaPOWER 500A Mk2 automatically controls the pump & heater to filter the water &

maintain it at the desired temperature as set by the user (see below). The user can leave the

system to look after the spa & know it will be at the correct temperature whenever he or she

wants to use it.

Adjusting Set temperature

The SpaPOWER 500A Mk2 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.

Sensed temperature

The sensed temperature (in the heater) can be

checked if necessary by pressing the Up & Down

buttons simultaneously. The display flashes while

showing the sensed temperature.
Heating mode Selection

In addition to the temperature setting the user can select the preferred heating mode. The two

available heating modes are....
1. Demand Heating (displayed as Ht.d). This is the default setting in which the pump & heater

will come on automatically whenever the temperature drops slightly below the set point.

2. Filtration Only Heating (displayed as Ht.F). In this mode the pump & heater will come on

automatically no more than once per hour to filter & heat the water. This mode is provided as

an option for those who prefer to limit the natural cycling of the system.

To select the heating mode first press the Pump & Down buttons simultaneously to display the

current heating mode, then press & hold the Up or Down buttons to change modes.
