	No LEDs light up after plugging in.	No power on the junction box.	Check the overload fuse of the connection.
		Miniature fuse defective.	Check the miniature fuse on the rear of the device. If it has melted, the power connection may not be installed properly. Check the polarity of the power connection before starting another test with a new miniature fuse. Use original miniature fuses only.
		The brightness of the LEDs has been set to 0.	Increase the brightness of the LEDs in the Fronius Solar.wattpilot app.
		"Switch off LEDs after 10 s in standby" has been enabled.	Deactivate "Switch off LEDs after 10 s in standby" or press the push button on the Wattpilot.

Does the Sanden Eco® heat pump hot water system require the assistance of an electric booster element to heat water, when outside ambient temperatures are very low?

No, unlike other competitor heat pump hot water (HPHW) systems, the Sanden Eco® HPHW system does not require an electric booster element

Should I get the official Sanden Quick Connection kit 15mm or 20mm?

The Sanden Quick Connection Kit includes the tempering valve, ECV (Expansion Cold Water Valve), elbows, insulation gloves for all the elbows and valves so you have the most efficient set up - you can't buy the insulation gloves separately. Makes the plumbing install much quicker (plumber only needs to source copper + lagging for the copper). Always highly recommended to ensure the Sanden is installed to specifications

Normally a house with upto 2 bedrooms is 15mm and 3+ is 20mm.

What are RECs and STCs, what are they worth? And how many do you get with your Sanden?

What are STCs and how many do you get with your Sanden?

The purchase and installation of a Sanden Eco® Plus Hot Water Heat Pump entitles you to Small-scale Technology Certificates (STCs) – formerly known as Renewable Energy Certificates (RECs). For more information: visit www.environment.gov.au/climate-change and www.cleanenergyregulator.gov.au

The Sanden HWHP achieves the highest level of STCs of any hot water heat pump, currently available in Australia, and these are as below:

To find out which zone your postcode is in click here (note this may change so if in doubt contact the clean energy regulator for more information)

The Table below shows how many STCs are available for each Sanden model in each STC Zone

How much are STCs worth?

STCs can be priced through the Government's STC clearing house or on the open market at places like Green Energy Markets.

So say you bought a Sanden GAUS-250FQS and you lived in zone 4 and the current STC price was $35

The total discount you would receive would be: 34 STCs x $35 = $1,190.

So you would receive a discount of $1,190 off the total price of your Sanden unit (note this is an example only to illustrate how STCs are calculated the actual discount will vary depending on the current STC price).

Is water quality an important consideration for the Sanden Eco® Plus heat pump hot water system?

Yes, importantly no warranty applies to the heat pump unit and the storage tank, where the chloride level exceeds 200 mg/litre and the pH is less than 6.0. If in doubt, seek water quality information from your local council or water supplier.

How does a heat pump hot water (HPHW) system work?

The Sanden Eco® Plus heat pump hot water (HPHW) system operates like a refrigerator in reverse. It contains a fan that forces air through an evaporator that contains a refrigerant. The heat in the ambient air passes through the evaporator (note: even air below 0 º C contains heat energy) and is absorbed by a natural refrigerant, R744 (aka CO_²), which is ozone friendly and does not significantly contribute to global warming compared with most other refrigerants (older style refrigerants have thousands of times more global warming impact for the same amount of gas, when compared with CO₂).

The warm gaseous refrigerant is circulated in the system via a compressor. As it passes through the compressor, its pressure rises, as does its temperature. This hot refrigerant then passes through a heat exchanger to heat the water, which is finally pumped to the storage tank.
