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.
If used with an extended Off-Peak (overnight and day) electricity supply, the timer switch should:

be operated by a continuous power supply on its own circuit from the switchboard with the booster heating
unit operated by the Off-Peak power supply. A double pole isolating switch is required to be installed at
the switchboard to simultaneously isolate both circuits.
or

be of a type which has an internal rechargeable battery to keep time when the power supply is not available
to the timer.
Refer to
“Booster Control”
on page 8 for information on programming the timer.
