DIAGNOSTIC FEATURES OF THE SOLAR CONTROLLER
The solar storage tank incorporates a solar monitor which is connected to the solar control module by a
ribbon cable. The solar monitor is located on the lower front cover and houses both a green and a red LED.
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.
The modes are:
Flashes Operational Modes
solid green
Standby mode
(remains on)
2 x green Flooding solar circuit
3 x green Pump flow control
4 x green Pump flow established
5 x green Tank at maximum temperature
no green
Call for service
(remains off)
Notes:
Warning: The removal of the lower front cover will expose 240 V wiring. Switch off the electrical
supply at the power outlet to the solar storage tank before removing the lower front cover and if
necessary disconnecting the ribbon cable from the solar control module. The lower front cover and the
ribbon cable must only be removed by a qualified person.
The ribbon cable connecting the solar monitor to the solar control module has sufficient length to enable
the removal of the lower front cover and for it to be set to one side of the opening, without disconnecting
the ribbon cable from the solar control module.
The ribbon cable can be disconnected from the solar control module if it is necessary to remove the
lower front cover completely from the work area in front of the solar storage tank.
If the ribbon cable from the solar monitor has been disconnected, reconnect it to the solar control
module prior to replacing the lower front cover.
