Unit installation

SOLAR CONTROLLER AND SOLAR MONITOR

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 from three to six flashes in each series of flashes. A constant

glow or pulsing of the red LED does not necessarily mean there is a fault with

the system.

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 tank 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 (the green LED will emit either a rapid pulse or a series of three

flashes), such as during start up if the solar collectors have not been covered,

it is possible the red LED may simultaneously emit a rapid pulse for a period

of up to ten (10) minutes.

This does not indicate a fault. Refer to “Commissioning” on page 14 for the

possible green and red LED 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.

COMMISSIONING

Refer to the installation instructions supplied with the solar storage tank for the

complete commissioning procedure.

When the electrical supply is switched on to the solar control unit at start up:

 If there is no solar gain, the circulator will not activate and the green LED will

emit a slow pulse.

The slow pulse indicates the circulator is not activated and the power to the

solar control unit has been on for less than 48 hours.

 If there is solar gain, the circulator activates and the green LED will emit a

series of three (3) flashes.

The three (3) flashes indicate the circulator is operating and power to the solar

control unit has been on for less than 48 hours.
