Notes:
Power must be available at the water heater and to the heat pump for
the LEDs to glow or flash.
Time controlled power supply
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.
If there is power to the water heater and the green LED is off or the red
LED is flashing, this indicates there may be a fault condition with the water
heater. The red LED may emit up to seven flashes in each series of
flashes. Refer to
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
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 seven 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 and the red LED has gone out. If the red LED has gone
out, when heating is next required, the green LED will flash and the
heat pump will commence to operate. If the heat pump stops
operating and the red LED recommences to flash, 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.
