PRINCIPLE OF CONTROL
CONTROL OPERATION :
The digital electronic thermostat control on the Heatstar unit is intended to automatically maintain the required
pool water temperature.
The thermostat measures the actual condition of the pool water as it is pumped through the Heatstar unit by the
pool filtration pump and automatically switches
‘ON or ‘OFF’ heating accordingly.
The control operates on a simple
‘ON’ or ‘OFF’ principle.
Heating, for example, will either be
‘ON’, if the pool water temperature is colder than the control setting, or ‘OFF,
if the pool water temperature is warm enough.
The control setting simply tells the Heatstar unit what temperature you consider to be
‘warm enough’.
The heat output available from the Heatstar is a fixed quantity and setting a higher pool water temperature will
not serve to increase the amount of heat produced from the Heatstar unit at all.
The control is intended to be completely automatic and, once correctly set, it should not require any further
adjustment at all.
The temperature control normally displays the actual current temperature of the pool water.
To set the desired pool water temperature :
AQUARIUS MODELS 1,2,3 & 4 :
On the digital thermostat, press and hold the left hand button (with both up and down arrows), which will then
display the set point temperature.
To increase the set temperature, whilst still pressing the left hand button, press the button by the
‘up arrow’.
To decrease the set temperature, whilst still pressing the left hand button, press the button by the
‘down arrow’.
When the left hand button is released, the new set temperature is fixed and the thermostat reverts to displaying
the actual current pool water temperature.
The product will now continue to heat the pool water until your desired set temperature is achieved, when it will
automatically switch off.
If the pool water temperature drops below your desired set temperature, the heat pump will automatically switch
back on again.
‘PLUS’ VERSIONS :
These versions also incorporate a direct electric resistance booster heater.
Press and release button
‘L1’ to display the temperature set point for heat pump operation. To increase or
decrease the set point, simply use the up or down arrow buttons.
Press and release button
‘L2’ to display the temperature set point for booster operation. To increase or decrease
the set point, simply use the up or down arrow buttons.
To achieve proper stage control, L2 would normally be set 2C below the setting for L1.
AQUARIUS MODELS 6,8 & 16 :
These models have twin heat pump circuits, which can be controlled independently.
Press and release button
‘L1’ to display the temperature set point for heat pump circuit 1 operation. To increase
