3.1 Running Principle
The Thermodynamic Solar System ECO is an equipment based on the principle of compression
refrigeration - Carnot's principle - which we call the Thermodynamic Solar Systems: Solar Panel and
a Heat Pump. The solar panel, which is the main component, placed outside ensures the capture of
energy on:
a) Direct and diffuse solar radiation;
b) Outdoor air, by natural convection;
c) The effect of the wind;
d) Rain water.
The temperature difference caused by the mentioned external agents, guarantees that the R134a
(ecological refrigerant) evaporates inside the solar panel.
The absence of glass on the panel allows to increase the thermal exchanges by convection.
After passing through the panel, the R134a is aspirated by the compressor, which raises its
temperature and pressure, which in turn is transmitted to the water circuit through a condenser
external to the tank.
Before the R134a returns to the solar panel, a choke must occur, that is, through a thermostatic
expansion valve the pressure is reduced and the fluid reaches its liquid state again, thus completing
the cycle.
This facility with which we combine technology with a law of nature (change of state of a fluid),
demonstrates the veracity and potential of ECO.

3.5 Safety and Control Devices
3.5.1 Low Pressure Switch
In case of running outside the range of pressures recommended and defined by the supplier, the
equipment will switch off and indicate error in the electronic panel.
3.5.2 Safety Thermostat
The safety thermostat is set by the supplier to ensure that the water temperature in the storage water
heater does not exceed the standard value. If the temperature exceeds this value, the thermostat
switches off the backup electrical heater. Switching on is done manually by qualified staff, after
analysing the reasons for the switch off.
3.5.3 Temperature Probe
The purpose of the temperature probe is to measure the temperature values of water in the storage
water heater in order to control the system.
3.5.4 Protection Against Corrosion (if applicable)
Besides being resistant to corrosion (stainless steel), the storage water heater has in addition a
magnesium anode that should be checked periodically according to information by the installer.
3.5.5 Dielectric Joint (enamelled boilers)
If the boiler is made of enamelled steel, the equipment contains two dielectric bushings. These
bushings prevent electrons from exchanging between the water inlet and outlet tubes and the water
heater itself. In this way, another protection against corrosion is created, which could be verified
especially in these points.
Thus, the bushings (A) must be tightened on the inlet (B) and water outlet (B) connections of the tank,
before placing the respective tubing (C).

6.5.3 PV Mode
The PV function offers the possibility to raise the water temperature when an alternative electrical
energy source is available (solar photovoltaic, wind or other), increasing the efficiency of the heat
pump and making the alternative electrical energy source more profitable.
To do this, simply connect a cable from the inverter to the equipment control board. The cable
connection on the control board must be made at the 5V / P2 terminals. Note that this is a dry contact
(no voltage), applying a voltage to this contact can cause irreversible damage to the controller.
When the K1 contact closes, the PV function is activated and all active heat sources (Heat Pump +
Electrical Heater) are adjusted to new operating parameters. The compressor will assume the
parameters P01PV / H01PV and the electrical heaters the parameters P02PV / H02PV.
Note: when contact K1 opens, the equipment assumes the operating mode previously adopted.
Contact K1 can also be used to take advantage of bi-hourly rates. To do this, simply connect a timer
to the 5V / P2 terminals instead of the inverter.

12.2 Magnesium Anode (if applicable)
This equipment has a magnesium anode that together with the building material of the tank
will provide an
effective protection against corrosion.
The internal shielding of the tank will ensure an effective protection against corrosion
contributing to a water quality within the parameters considered normal. However, the
characteristics of the water change according to the installation. (See Chapter 4.5 and
warranty)
In your living area, the quality of the water can be aggressive to your equipment. So together
with the equipment there is a magnesium anode that wears over time, thus protecting your
equipment.
The wear of the anode always depends on the characteristics of the water you use. Thus,
checking the condition of the anode is very important, particularly in the first years of the
installation. To check the condition of your anode, follow these steps:
•
Unplug the appliance from the power supply
•
Shut off water supply
•
Remove pressure (for example, open a hot water tap)
•
Unscrew the anode with a suitable tool
•
Check the level of wear of the anode and replace it, if necessary
•
If the diameter of the anode is less than 15mm, it will need to be replaced
The extension of the deposit's anti-corrosion guarantee is conditioned to the sending
of documentary proof of the annual replacement of the magnesium anode.
12.3 Filter of Reduction Valve
To periodically clean the filter of the reduction valve, you should:
a) Shut off the water supply;
b) Turn anti-clockwise until you remove tension from the spring;
c) Remove the handle;
d) Remove filter and clean.
12.4 Safety Thermostat
The safety thermostat is disarmed whenever there is an anomaly in the system, so,
whenever you want to rearm it, find out what happened for it to have acted.
If you do not find out what happened and it is still disarmed, contact after-sales service to
have your case resolved.
If everything is in order and you want to reset the thermostat, proceed as follows:
Remove the bonnet by loosening the four screws present;
• Unscrew the cover (1);
• Press button (2) to reset the thermostat;
•
Retighten the cover (1) and replace the bonnet, tightening the four screws again.
