BOOSTER CONTROL
The isolating switch installed in the electrical meter box for the solar storage tank should be left switched on.
Leaving the isolating switch switched on will also provide a sufficient period of time each day for the booster
heating unit to operate, if required, to satisfy the requirements of AS 3498.
Timer Control Switch
A suitably rated timer control switch can be installed and will help maximise energy savings with an
electrically boosted solar water heater connected to a continuous, time of use or extended Off-Peak
(overnight and day) electricity supply.
Electricity Supply to the Solar Controls and Timer
An active from a continuous circuit on the switchboard is required to operate the solar controls. This active
will need to be looped prior to the timer with the looped active wire bypassing the timer and connecting
directly to the active terminal marked A1 (marked "Controller" on the wiring diagram) on the terminal block of
the solar storage tank. This is a requirement if the booster heating unit is connected to either a continuous or
an extended Off-Peak / extended time controlled (overnight and day) electricity supply and a timer control
switch is installed.
This supply must remain uninterrupted to allow the solar controls to operate and solar gain to be achieved
and must not be switched by the timer control switch. This active will also operate the timer.
Continuous or Time of Use Supply to the Booster Heating Unit
A second active wire, switched by the timer, must be connected to the active terminal marked A2 (marked
"Booster" on the wiring diagram) on the terminal block of the solar storage tank.
The wire bridging the two active terminals marked A1 and A2 (marked "Controller" and "Booster" respectively
on the wiring diagram) on the terminal block is not required and must be removed if a timer control switch is
installed.
Refer to the continuous power supply wiring connection diagram
connection wiring diagram
Extended Off-Peak Supply to the Booster Heating Unit
The active from the extended Off-Peak circuit must be switched by the timer and connected to the active
terminal marked A2 (marked "Booster" on the wiring diagram) on the terminal block of the solar storage tank.
A double pole isolating switch is required to be installed at the switchboard to simultaneously isolate both
circuits.
The wire bridging the two active terminals marked A1 and A2 (marked "Controller" and "Booster" respectively
on the wiring diagram) on the terminal block is not required and must be removed if the booster heating unit
is connected to an Extended Off-Peak power supply.
