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 

 on page 2. 

 
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.
