What are the Status Error Codes and Remedy for my Fronius Wattpilot EV Charger?

Status codes and remedy on Fronius Wattpilot EV Charger

Due to phase, voltage and switching function checks of the Fronius Wattpilot, a charging operation may be rejected.

The status codes are displayed via the LED status indicator (see LED status indicator on page 17) directly on the Wattpilot and in the app under "Status".

Status Codes	Issue	Cause	Remedy
1	Fault current detected (LEDs light up pink, the LEDs at the top flash red)	The residual current device has detected an error.	The charging equipment in the vehicle may be defective. Have the charging equipment checked by a specialist.
1		The residual current device has detected an error.	Disconnect and reconnect the charging cable.
3	At least one phase of the power supply is missing (the LEDs light up blue, the LEDs at the top flash red)	The device is only being supplied with 2 phases.	Make sure that phase 2 and phase 3 are connected correctly. Option: a supply via phase 1 only is possible.
8	Grounding fault detected (the LEDs light up green and yellow, the LEDs at the top flash red)	Grounding fault detected.	Check that the connection is properly grounded.
10	Relay fault detected	The relay has not switched.	Disconnect the power supply to the device for 5 seconds.
11	Backup power mode detected	53 Hz mains current detected.	Observe the instructions in the Operating Instructions.
12	Type 2 plug locking failed	The plug locking system does not work.	Remove possible foreign parts in the plug housing.
12	Type 2 plug locking failed	Type 2 plug not fully inserted.	Insert the type 2 plug into the device as far as it will go until you hear a click.
13	Type 2 plug unlocking failed	The electric vehicle is plugged in.	Unplug the electric vehicle.
		"Always locked" under "Cable release" in the Solar.wattpilot app is activated.	Deactivate "Always locked" under "Cable release" in the Solar.wattpilot app.
		Release jammed.	Insert the type 2 plug into the device as far as it will go until you hear a click. If the problem has still not been fixed: Press the push button on the device. If the problem has still not been fixed: Activate and save "Always locked" in the Solar.wattpilot app, then activate and save "Standard mode" under "Cable release".
100	Internal communication error (all LEDs flash red)	Device is not sending data.	Disconnect and reconnect device.
			Perform a firmware update.
			Return device.

Why does the Sanden Eco® Plus use CO2 as its working gas? Isn’t CO2 a greenhouse gas and therefore harmful to the environment?
Why does the Sanden use CO2 as its working gas, what is the benefit?
- There is far less environmental impact (i.e. No ozone layer depletion and minimal global warming) than other commonly used refrigerants, should the system leak.
- There is a much higher efficiency, thereby allowing more heat to be transferred to the water, for less energy used (i.e. Excellent thermodynamic ability).
Isn't CO2 a greenhouse gas and therefor bad for the environment?

While it is true that Carbon Dioxide (CO₂) is a greenhouse gas it has a Global Warming Potential (GWP) of 1. Whereas refrigerant gases in other heat pumps can have GWP of over 10,000, which means if they leak to the atmosphere they contribute 10,000 times more to global warming compared with the refrigerant gases used in a Sanden Eco Plus.

The table below shows the GWP for some common refrigerant gases (note: GWP must include a time interval over which the greenhouse gases act, in this case 100 years)

Our system utilizes less than 1 kg of R744 (CO²) as a refrigerant contained in a closed system at the factory. The installer does not need to charge the heat pump on site.

Sanden Eco Hot Water Tank Size Options? Which tank size should I choose?

The Sanden Eco Plus hot heat pump hot water system is available in the following five sizes with our sizing guide below:

Tank size/shape	Tank Code	System	No. of People	No. of Bathrooms	Dwelling type	Off-peak & Continuous tariffs?	Tank Diameter (mm)	Tank Height (mm)
160L SS	SAN-160SAQA	GAUS-160FQTS	1	1	Bedsits	Continuous only	621	970
250L SS	SAN-250SAQA	GAUS-250FQTS	1-3	1-2	Residential	Both	621	1428
300L Tall SS	SAN-300SAQA	GAUS-300FQTS	2-6	1-3	Residential	Both	580	1891
315L SS	SAN-315SAQA	GAUS-315FQTS	2-6	1-3	Residential	Both	621	1748
315L VE	SAN-315VE	GAUS-315FQTV	2-6	1-3	Residential	Both	638	1626

*SS = Stainless Steel // VE = Vitreous Enamel

The same Sanden Heat Pump condenser unit is used in combination with different tanks sizes. So which tank size you would like?

When considering tank sizes - we need to consider a few factors - number of people, number of bathrooms, the heat recovery rate.

If you're using an existing hot water system for comparison - here are some comments/thoughts:

If you have an existing gas storage hot water system (e.g. 130L / 170L) - these are much smaller in capacity but they will reheat several times a day. Therefore the Sanden tank size will be larger than an existing gas storage replacement with the Sanden re-heat typically only required once per day - a good opportunity to maximise rooftop solar PV production or to utilise an off peak tariff.

If you have an existing electric storage hot water system (e.g. 400L 3.6kW unit) - these electric storage 3.6kW units recover heat at a slower rate (60L/hr) compared to a Sanden heat pump (approx. 80L/hr). Therefore a 400L electric storage hot water system would equate to a 300L/315L Sanden system in this example.

Based on our years providing the Sanden Eco heat pump hot water system - here are our tank recommendations for different scenarios (SS - Stainless Steel // VE - Vitreous Enamel):

160L SS: Only recommended for 1 person bedsits. This tank size is rarely chosen and due to its small tank size must be run in Continuous only mode (no blockout timer can be set up).

250L SS: Typically 1-3 person household with 1 bathroom. Height just under 1.5m with tank diameter 621mm.

300L SS: The Tall Slim - the most popular and best recommended tank choice. Recommended for 2-6 people. Tank diameter 580mm and tank height just under 1.9m. If no height restrictions apply, this is the recommended tank for majority of situations and considered best value for money across the tank sizes.

315L SS: The largest tank size with an additional 15L delivered hot water (5% more) compared to the 300L Tall Slim tank. Tank diameter 621mm with tank height 1.74m - this is recommended if the 300L tall slim tank is too tall for your application.

315L VE: Tank diameter 638mm with tank height 1.63m with 315L delivered hot water. This VE tank is specified for poor water quality areas - you can identify if you are in a poor water quality area via the Sanden website -> https://www.sanden-hot-water.com.au/check-water-quality/

There is a red LED flashing on the display panel should I be worried?

The flashing red dot (LED) indicates the Sanden is currently in 'sleep mode', it is perfectly normal and nothing to worry about.
