TECHNICAL INFORMATION

3.1. Operating Principle

1. The evaporator captures the thermal energy from the air through the refrigerant.
2. The compressor compresses the refrigerant, increasing its temperature and pressure.
3. The collected energy is transferred to water in the condenser. The accumulated water in- creases its temperature reaching up to 55 ºC.
4. The refrigerant circulates to the expansion valve, where its pressure decreases to achieve the optimum conditions before entry into the evaporator.

INSTALLATION STEPS

Before starting the installation, check the availability of all the necessary components and tools:

• Drill
• Screwdriver
• Hydraulic installation components
• Electric installation components

Once it has been checked that it is available all the necessary components and tools, the installer should follow the next steps:

1. Placing the unit
2. Hydraulic installation
3. Air connections
4. Electric installation
5. Commissioning

PLACING INDOL-UV4 UNIT

The place where the system will be installed should allow an easy access to make maintenance work or inspection.
Air outlet of the unit is around 5-IO degrees below inlet temperature, so in case that the exhaust air would not be ducted, the room temperature will be considerably reduced.
Beside these factors, it is important to consider the following indications regards the installation site:
The system has been designed and manufactured for it indoors utilization. Install the system in a dry, frost-free room at a minimum temperature of 5 °C.
Installer must install the supplied silent blocks to avoid the transmission of vibration.
The wall where the system will be installed has to bear the weight of the system full of water.

WALL INSTALLATION

The device is designed for wall-mounting installation, therefore is supplied two brackets in the back. The installer has to fix coach screws M10x80, lock washer M10 and screw anchors 12×60.
In addition, there are two holes on each side to adjust and regulate the silent blocks supplied to the wall.

AIR CONNECTION

Indol-UV4 unit has two air connections located at the top cover of the system.
There are different installations possibilities:

Since the temperature of the exhaust air is lower than the intake air flow, the user can recover this cold air to refresh a room. In this case, it is recommended to install a double duct, one to the room and other to outdoors. Using a gate, the user can stop the air  flow conducting it to outdoors when cooling isn’t needed.

IMPORTANT:

• Do not use flexible duct! Only smooth PVC pipe is allowed.
• Do not use anti-insect grid.

When the inlet and outlet ducting is needed, use only rigid smooth PVC be.
The pressure drop in the whole air circuit (pipes and accessories) must be lower than the static pressure of the system, 50 Pa. In the following table is shown the allowed total pipe length (intake + exhaust). The equivalent length of any accessory installed in the  circuit must be subtract to the maximum allowed pipe length:

SUCTION FILTER
The system includes in the air intake a filter for the protection of all the elements of the refrigeration circuit.
This filter should be checked every 6 months to verify that is has not been clogged. To do this, remove the filter from the suction duck and check if the channels allow air passage, Otherwise, wash it with water or replace with a new one.
If you notice_that the system does no heat up, check_the condition of the_filter.A_clogged filter gffects the life-cycle performance_and_hot water production_of the_system.

10.2. INSTALLATION. Switching on

After full installation of the water heater (power and water pipes connected) and after the water heater tank is full of water, power can be turn ON.

| 1. After filling the tank of water, connect the mains plug to the mains supply.
The screen will show the symbol.
2. Hold the key for 4 seconds. The
display will show the icons.
3. The screen will show the water temperature.

10.3. Switching OFF

To switch off the system, hold the key for 4 seconds.

10.4. Unlocking the keypad

When 30 have elapsed without the keys being pressed, the display will show the “Loc” label and the keypad will lock automatically.
Touch any key until the screen shows “Unl”, to unlock the keypad.

10.5. Displaying the operating mode
At trst imal power ON, the product goes, by default, in Eco mode. By touching one time the V key, the controller will show the mode in operation in this moment.

10.6. Changing operating mode

10.7. ECO Mode
ECO mode: Maximum savings. The system heats water only by heat pump technology.
This is the factory default mode.
Setting the ECO temperature setpoint
The water temperature set point in ECO mode can be changed with the SPl parameter.

10.8. AUTO Mode
It maintains a steady temperature by the heat pump and only use the electrical heater if the temperature falls drastically.
Setting the AUTO temperature setpoint
The water temperature set point in AUTO mode can be changed with the SP2 parameter.

10.9. OVERBOOST Mode
Select this mode to achieve a fast heating by using simultaneously heat pump and electric heater.
This mode Works as a rapid heating. Once the setpoint temperature is reached, the system returns to the initial mode.
If Overboost mode is switched on when the system Works from ECO node. The system heats the water up to SPl, and then returns to ECO again
If Overboost mode is switched on when the system Works from Auto mode:. The system heats the water up to SP2, and then returns to Auto again
When Overboost mode is active, the display automatically changes showing the water temperature and Obs.

Cancelling the Overboost Mode

Parameter SP3 allows to set the minimum temperature that Overboost can be actived.
To change it value, follow the procedure:

10.10. Photovoltaic input
Working on this mode, the system automatically heats the water due to electric energy surplus or by Off Peak rate.
The parameters of this mode can only be changed by the Installer’s Menu.
Contact with the technician for more information.
The system can be combined with and Photovoltaic Inverter to take advantage of the surplus energy generated by the panels, by forcing the system working and storing this energy in useful hot water.
The system has in the electric boar two terminals to connect a zero-voltage contact.

When the contact is closed, the system automatically changes to Photovoltaic mode and the heat pump and electric heater work to achieve the programmed temperature. When the contact is opened, the system returns to the previous mode.
This contact can be also used for Of Peak Rates. To do it, connect into the contact a timer with a zero­ voltage output.

10.11. Displaying/deleting compressor functioning hours

10.12. Antilegionella
The anti-legionnella feature reduces the risk of development of bacteria in the tank.
The system performs a thermal shock disinfection to avoid any risk conditions that might cause the development of bacteria. The disinfection is made automatically once a month, reaching a temperature of 65 °C.
Anti-legionella can be disable or enable in the installer menu.

IMPORTANT: When the system is switched off from electrical supply, the internal hour-counter for antilegionella disinfection is reset. For this reason, the system will perform a thermal shock disinfection before the time expected.
