CONNECTIONS – ELECTRICAL 

 

The power supply to the water heater must not be switched on until the water heater is filled with water. 

 
All electrical work and permanent wiring must be carried out by a qualified person and in accordance with the 
edition of the Wiring Rules AS/NZS 3000 in force in the state or territory at the time of installation, and all local 
codes and regulatory authority requirements. 
 
The power consumption of the water heater is:

Maximum load during anti-freeze cycle 

 

1234 Watts

The water heater will only operate on a sine wave at 50 Hz. Devices generating a square wave cannot be used 
to supply power to the water heater. 
 

SOLAR CONTROL UNIT 

The  solar  control  unit,  supplied  with a  1.8  metre  power  cord,  requires  a  switched  240  V  AC  50  Hz  general 
purpose  outlet (GPO) to be located  within 1.2 metres of the  installation. The GPO must have a continuous 
power supply. The GPO is required to be weatherproof if installed outdoors. 
 
The anti-freeze heating unit is supplied with power from the power outlet via the solar control unit. A flexible 
20 mm conduit is  provided for the electrical cable from the solar control unit to  the solar storage tank. The 
conduit is connected to the solar control unit and the solar storage tank with 20 mm terminators. 
 
The power outlet to the solar storage tank must be switched on for the solar control unit to operate and solar 
gain to be achieved and for the anti-freeze heating unit to operate and offer additional freeze protection. 
 
The anti-freeze heating unit is rated at 1200 watts. 
 

 Warning:

 If at any stage the heating unit requires replacement, the replacement heating unit

’s rating must 

not  exceed  1200  watts.  Fitting  a  heating  unit  with  a  power  rating  greater  than  1200  watts  will  damage  the 
differential controller in the solar control unit. 
 
The solar control unit automatically controls the flow rate through the collector circuit. This is achieved via the 
hot  and  cold  sensors  and  differential  controller  programming  providing  control  over  the  operation  of  the 
circulator. There is no provision for nor is adjustment to the solar control unit required. 
 

THERMOSTAT SETTING 

The  temperature  setting  on  the  thermostat  connected  to  the  anti-freeze  heating  unit  does  not  need  to  be 
adjusted as this thermostat does not provide temperature control. Its primary function is to provide an energy 
cut-out  in  the  event  the  solar  controller  fails  to  turn  off  power  to  the  anti-freeze  heating  unit.  Temperature 
control for the freeze protection function is provided by the differential controller in the solar control unit.
