COMMISSIONING
Notes:
There is no 2 x red flash indicator or fault mode code.
Power must be available at the water heater and to the heat pump for
the LEDs to glow or flash.
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.
Heat pump operating range (power must be available to the heat
pump)
The heat pump‟s operating range is between an ambient air temperature
of a minimum of 3°C to 5°C and a maximum of 45°C to 55°C. The heat
pump will not operate when the ambient air temperature is outside the
heat pump‟s operating range.
If heating is required, the water heater will commence heating with the
booster heating unit in booster heating mode (long green flash) instead.
The water will be heated to 70°C during these periods.
At the completion of this heating cycle by the booster heating unit (long
green flash), the thermostat controlling the booster heating unit opens
circuit cutting power to the heat pump causing the green LED to go out.
This is not a fault condition, but a result of the power being cut to the heat
pump by the thermostat.
Refer to "Heat pump operating range" in the "Save A Service Call" section
of the Owner‟s Guide and Installation Instructions supplied with the heat
pump storage tank for further explanation.
