Notes:
Red LED Illuminated
Solid Red or 3 x Red Flashes (Green LED Off) – If the power supply to
the water heater is on and the green LED is off and the red LED is emitting
a solid glow or three (3) flashes, this does not necessarily mean there may
be a fault with the water heater but is indicating the water heater is
operating outside of the heat pump‟s operating range. The heat pump‟s
operating range is when the ambient air temperature is 5°C or higher.
Refer to “Heat pump operating range” in the “Save A Service Call” section
of the Owner‟s Guide and Installation Instructions supplied with the
storage tank.
1 x Red Flash (Solid Green LED) – If the green LED is emitting a solid
glow and the red LED is flashing a single flash, this does not necessarily
mean there may be a fault with the water heater. Refer to “Red and Green
LEDs Are Illuminated” in the “Save A Service Call” section of the Owner‟s
Guide and Installation Instructions supplied with the storage tank.
Other Red Flash Sequences – If the red LED emits a series of flashes
other than three (3) flashes (green LED off) or a single flash (green LED
solid glow), there may be a fault with the water heater.
Before phoning to arrange a service inspection due to the red LED flashing
or the green LED not illuminating refer to “Heat Pump Is Not Operating”,
“Green and Red LEDs Are Not Illuminated On Operating Mode Monitor”,
and “Red LED is Illuminated – Green LED is Off” in the “Save A Service
Call” section of the Owner‟s Guide and Installation Instructions supplied
with the storage tank.
Power must be available at the water heater and to the heat pump for
the LEDs to glow or flash.
If there is power to the water heater and the green LED is off or the red
LED is flashing (other than 3 x red flashes with the green LED off, or a
solid red glow, or a single red flash with a solid green LED), this indicates
there may be a fault condition with the water heater. The red LED may
emit up to seven (7) flashes in each series of flashes. Refer to “Possible
fault condition” on page 27.
Time controlled power supply (power must be available at the water
heater)
If the water heater is connected to a time controlled power supply, then
during periods of no power supply at the water heater the LEDs will be off.
This is not a fault condition, but a result of no power being available to
energise the LEDs. The green LED will recommence glowing or flashing
when power is available again at the water heater.
