HOW YOUR WATER HEATER WORKS

SOLAR MONITOR
The solar storage tank incorporates a solar monitor. 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 flashes.
The red LED will emit a series of flashes, with a 2 second interval between
flashes, only if there is a particular fault condition with the system.
The operational modes are:
Flashes Operational Modes
solid green
(remains on)
Standby mode
1 x green Flooding solar circuit
2 x green Checking solar contribution
3 x green Pump flow control
4 x green Pump flow established
5 x green Tank at maximum temperature
no green
(remains off)
Call for service
If the power supply to the water heater is on and the green LED is off or the red
LED is flashing, this indicates there is a fault with the water heater. The red
LED may emit up to five flashes in each series of flashes. Count the number of
flashes and phone your nearest Rheem Service Department or Accredited
Service Agent to arrange for an inspection.
GOING ON HOLIDAYS
It is not necessary to switch off the electrical supply at the isolating switch to
the water heater if you are going away. However, if it is necessary to switch off
the power to the water heater, refer to
