COMMISSIONING
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 above 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 two (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)
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 six (6) flashes in each series of flashes.
Count the number of flashes and phone Rheem Service or their nearest Accredited Service Agent to arrange
for an inspection.
IN-SERIES BOOSTER
Refer to the Owner's Guide and Installation Instructions supplied with the in-series booster for the
commissioning procedure of the water heater.
If a gas water heater has been installed as an in-series booster to the solar water heater, then to complete the
installation, it is necessary to check the gas supply pressure at the inlet to the in-series gas booster, and also
the minimum test point pressure and the maximum test point pressure of the in-series gas booster. Refer to
"Gas Inlet Pressure"
on page 58 and to
GAS INLET PRESSURE
IMPORTANT - CHECK the gas supply pressure at the inlet to the water heater with the water heater and all
other gas burning appliances in the premises operating (burners alight). The minimum gas supply pressure is:
Natural Gas
If this minimum cannot be achieved, it may indicate the meter or the gas line to the water heater is undersized.
It is important to ensure that an adequate gas supply pressure is available to the water heater when other gas
burning appliances, on the same gas supply, are operating.
Refer to the "Gas Inlet Test Point Pressure" section of the Installation Instructions and Owner's Guide supplied
with the in-series gas booster.
