Self Diagnostic Error Codes:
The Spa Power 500 controller has extensive self 
diagnosing abilities. In the event of a problem it will 
indicate an error number according to the nature of the 
problem. These are indicated by an alarm beeper beeping 
out the error number and by either the bargraph 
simultaneously flashing the corresponding dots up to the 
error number or the digital display indicating the error 
number The error numbers and their meanings are listed 
below.
Error 1 (H2O) = PRIME FAILED
Primefailed is a special case. This is not necessarily a 
problem with the Spa Power 500 itself, but indicates that no 
water is being sensed in the heater. On the push of the 
pump mode button the pump will run for 10 seconds to try 
get water to the heater. If successful, normal operation will 
resume. If unsuccessful Error 1 will be indicated again.
Error 2 = not used.
Errors 3-8 = are fatal errors.
Operation will stop and will not continue until the controller 
is reset (switched off and on again at the main power).
Error 3 = STUCK BUTTON
This error indicates that one of the buttons in the control 
panel is stuck or has been held down for more that one 
minute. This may be caused by water getting into the 
panel or by damage to the control panel.
Error 4 = NO WATER SENSOR
This error indicates a problem with the optical water 
sensor in the heater. It may also be caused by the sensor 
being disconnected inside the unit or by damage to the 
sensor.
Error 5 = OVERTEMP
This error indicates that the digital temperature sensor in 
the heater has detected a temperature of 45°C or more. 
This is not necessarily a problem with the Spa Power 500 
itself. It might be caused by excessive pump use during 
very hot weather or by disconnection or failure of the pump 
(no water flow).
Error 6 = KLIXON TRIPPED
This error indicates that the safety electromechanical over
temperature cut out on the heater has operated. This is 
not necessarily a problem with the Spa Power 500 itself. It 
might be caused by high temperatures during shipping, 
e.g. in the back of a sealed truck, or it might be caused by 
disconnection or failure of the pump. This cut out can be 
reset by pushing the red reset rod in the controller.
Error 7 = STUCK RELAY
This error indicates a problem with the heater control 
circuitry inside the unit.
Error 8 = NO TEMP DATA
This error indicates a problem with the digital temperature 
sensor in the heater. It might be caused by the sensor 
being disconnected inside the unit or by damage to the 
sensor.
Installation:
1. The heater should be located: 
(a) on the pressure side of the pump. 
(b) before the filter on the return line and before
chlorinators and ozone injectors (if fitted).
(c) where it is accessible for maintenance and with
enough clear room to remove the control head 
from the heater body.
2. The heating system must be installed in an enclosure
rated IP24, ie. it must be totally protected against water 
from all directions.
3. All installations must comply with AS3100 and any
additional requirements of your local supply authority 
including any relevant code of practice.
4. The heater body may be plumbed so the water can be
in either direction when mounted horizontally. If 
mounted horizontally, the heater must be mounted with 
its outlet sockets to the top so the safety water 
detection circuits are effective. Please note label on 
heater head which indicates correct side up.
5. Supply cord damage
If the supply cord of the equipment is damaged, it 
must be replaced by a repair shop appointed by the 
manufacturer because special purpose tools are 
required.
