CONGRATULATIONS
Congratulations on choosing the latest SpaPOWER 500A Mk2 control system. This
controller makes use of the latest technology, including innovative optical & digital sensor
designs. The user friendly touchpad & reliable components provide you with the best
value controller in its class.
TEMPERATURE CONTROL
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.
