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.
Possible fault condition
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
 the water heater has not operated outside of the heat pump‟s
operating range.
Before phoning to arrange a service inspection due to the green LED
being off, refer to “Heat Pump Is Not Operating” in the “Save A
Service Call” section of the Owner‟s Guide and Installation
Instructions supplied with the heat pump storage tank.
or
 the red LED is flashing – the red LED may emit up to nine flashes in
each series of flashes
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. When heating is next required the red LED will
recommence to flash the fault code for thirty (30) seconds and then
extinguish. If the red LED then recommences to flash or
recommences to flash after the heat pump next operates, 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” in the “Save A Service
Call” section of the Owner‟s Guide and Installation Instructions
supplied with the heat pump storage tank.
