DISPLAY PANEL
ECO MODE
The ECO (Energy Conservation Only) Mode is the standard day to day operational and heating mode by the
heat pump. This mode allows for the Heat Pump to operate during normal operation when heating is
required. The ECO icon illuminates on the Display Panel.
The heat pump will operate when there is:
•
electricity supply to the water heater, and
•
the water heater is turned "On" at the Display Panel, and
•
the water temperature in the lower part of the water heater is greater than 11°C below the Hot Water
Temperature Set Point, and
•
the ambient temperature is between the heat pump's operating range of -7°C to 43°C.
If the heat pump operates between -7°C and 7°C for an extended period of time, the electric heating unit
may turn on to assist in the heating of the water.
The electric heating unit will operate if the ambient air temperature is outside of the heat pump's operating
range of -7°C to 43°C and heating of the water is required.
USEABLE HOT WATER QUANTITY DISPLAY
The Display Panel features a Useable Hot Water Quantity display icon. This icon indicates the quantity of
usable hot water in the water heater. The more bars illuminated, the more hot water there is available.
The display ranges from no illumination of bars, which indicates the
average temperature of the water in the water heater is below 36°C,
to the illumination of twenty five bars, which indicates the water
heater is full of hot water. The number of bars illustrate the average
water temperature in the water heater calculated from the water
temperature in both the upper part and lower part of the water
heater. It is an approximation only.
The first solid vertical bar represents an average tank temperature of 36°C. Each subsequent solid bar
represents an increase of average water temperature in the water heater by 1°C. When all 25 bars are
illuminated solid, the average tank temperature is 60°C or above. It may be above 60°C if the Hot Water
Temperature Set Point is greater than 60°C.
Whilst the water heater is heating water, the illuminated bars will fluctuate back and forth from left to right.
FAULT CODES
The Main Display Area will display a fault code in the event the water heater develops a fault. In addition, a
one off six (6) second beeping alarm will sound from the Display Panel if a fault code is displayed.
The fault code will display alternately with the average water temperature in the water heater. If there is more
than one fault code, each code will display alternately with the other fault code(s) and the average water
temperature.
The fault codes which may appear are:
•
E0, E2, E3, E4, E5, E6, E7, E8, EF – The heat pump will not operate. The electric heating unit will
operate to heat the water when heating is required, to provide hot water until a service call is made to
repair the fault.
•
EA – The heat pump and electric heating unit will not operate and there will be no heating of the water.
•
EC – The heat pump and electric heating unit will not operate. This is an over-temperature fault which
will reset when the water in the bottom two thirds of tank is replaced with cold water as hot water is
drawn off. If the fault reoccurs, a service call must be made.
If one or more of the above codes is displayed on the Display Panel, make a note of the fault code(s) and
phone Rheem Service or their nearest Accredited Service Agent / Centre to arrange for an inspection.
