Possible fault condition
If the heat pump has developed a fault, the heat pump will not operate and
the red LED will flash a fault mode of a series of up to seven (7) flashes.
The green LED may also simultaneously flash or display a solid glow.
There may be a fault condition with the water heater if either:
there is power available at the water heater and the green LED is off,
and either
the water heater is not operating outside of the heat pump‟s
operating range, i.e. booster heating unit is not heating the water
(normally three red flashes or solid red glow if heating is
occurring) due to a cold ambient air temperature condition, or, or
the ambient air temperature is not below 0°C (normally solid red
glow if ambient air temperature is below 0°C).
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) –
the red LED may emit up to seven (7) flashes in each series of
flashes. The green LED may also simultaneously flash or display a
solid glow.
The fault condition which led to the red LED flashing may be cleared
after the backup heating cycle by the booster heating unit has
completed. If the red LED continues to or recommences to flash, or
recommences to flash after the heat pump next operates or attempts
to operate, a service call may be required.
Before phoning to arrange a service inspection due to the red LED
flashing, refer to “Heat Pump Is Not Operating”, “Green and Red
LEDs Are Not Illuminated On Operating Mode Monitor”, “Red LED is
Illuminated – Green LED is Off” and “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.
