The timer control switch should be programmed:
to suit the hot water consumption pattern of the household,
with the end of the period to coincide with the commencement of the evening hot water usage,
to enable a boosting period of not less than the recommended continuous length of time for boosting,
and
for a period when power will be available to the timer.
It may be necessary to program a second period into the timer, such as prior to the morning hot water usage.
Check with the householder.
The recommended continuous length of time for boosting is:

The recommended boosting periods are sufficient to allow the booster heating unit to heat up the boost
volume of the solar storage tank to 60°C where the winter cold water temperatures do not fall below those
shown. This may be necessary during periods of very low solar energy gain through the solar collectors,
such as during constant rain or extremely cloudy weather, particularly in winter when the incoming cold water
temperature is lower. The period will also provide a sufficient heat up time for the electric booster to operate,
if required, to satisfy the requirements of AS 3498.
