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 water heater.
The red LED may emit up to six flashes in each series of flashes.
Note: During periods of high solar radiation and if the circulator activates after
having been off, such as during start up, it is possible the red LED may emit a
rapid pulse for a period of up to ten (10) minutes. This does not indicate a fault.
Refer to
"Commissioning"
flashing sequence during start up procedure.
If the red LED continues to emit a rapid pulse for longer than ten (10) minutes,
or emits a series of flashes, then count the number of flashes and phone your
nearest Service Department or Accredited Service Agent to arrange for an
inspection.
