Is there a leaking hot water pipe, dripping hot water tap, etc?
Even a small leak will waste a surprising quantity of hot water and energy. Replace faulty tap washers
and have your plumber rectify any leaks.
Is the booster operating too frequently?
Refer to
“Gas Booster Operating Too Frequently” on page 12.
Has there been an increase in hot water usage?
An increase in hot water usage may result in an increase in gas booster operation.
Has your gas tariff rate been increased by your energy retailer since your previous account?
Check your previous bill and compare gas rates and charges.
If you have checked all the previous troubleshooting points and still believe you need assistance,
phone Aquamax Service or their nearest Accredited Service Agent.
Solar Monitor LED Indication
A solar monitor is located on the side of the solar control unit and houses a green and a red LED (refer to
“Solar Controller Major Kit Components” diagram on page 18 for solar control unit location).
The green LED,
marked „SOLAR‟, indicates the current operational mode of the solar water heater and the
red LED, marked “ATTENTION”, indicates a fault mode.
The green LED will emit either a constant glow or a series of flashes, with
a 2 second interval between each series.
The red LED will emit a series of flashes, with a 2 second interval
between each series, only if there is a particular fault condition with the
system.

If the power supply to the solar control unit is on and the green LED is off or the red LED is flashing, this
indicates there may be a fault with the solar water heater. The red LED may emit up to six flashes in each
series of flashes.
Notes:
If the system is in standby mode with the green LED emitting either a constant glow or slow pulsing
flashes (circulator is off) and the solar storage cylinder is full of hot water, the red LED may
simultaneously emit a constant glow if solar radiation is still being received by the solar collectors. This
does not indicate a fault. The red LED will go out when the temperature in the solar collectors
decreases.
During periods of high solar radiation and the circulator activates after having been off (green LED will
emit either a rapid pulse or a series of 3 flashes), it is possible for the red LED to simultaneously emit a
rapid pulse for a period of up to ten (10) minutes. This does not indicate a fault. If the red LED continues
to emit a rapid pulse for longer than ten (10) minutes, or emits a series of flashes, count the number of
flashes and phone Aquamax or an Accredited Service Agent to arrange for an inspection.
