Switch on the electric water heater
1.
Before initial start of the appliance, please make sure that the water heater has
been correctly connected to the electrical network and that it is filled up with
water. Switching on the water heater is done through the device incorporated in
the installation, which is described in sub-item 3.2. of section IV, or by inserting
the plug into an electrical socket (for models with cord with a plug).

Press the button to switch the appliance on. The operating mode set is displayed
on the control panel. Press the
Stand By mode is activated and the unit automatically enters the Anti-freeze mode. The

Operating control mode

The button selects the operating mode. Each time you press the button, a mode is
selected in sequence as follows:
WARNING: The maximum number of showers depends on the capacity of your
appliances and the method of installation. (fig. 1.3 horizontal or vertical).
Manual control mode
In manual mode, the appliance works like an ordinary electric water heater. The
amount of hot water is set as equivalent to the number of showers.
The set amount of hot water and the current status of the appliance are indicated by
indicator lights on the control panel.
The "shower" symbol gives you information about the amount of hot water that is
already heated depending on the number of showers. On the control panel, the
indicator light provides feedback on the selection made.
When the "shower" symbol is lit constantly, this means that the set amount of hot
water has been reached, but when the "shower" symbol flashes, this indicates that the
appliance is heating mode.
When more than one of the set "showers" are not ready, the corresponding "shower"
symbols blink one after the other constantly. This gives inforamtion about the set
amount of hot water, as well as the amount reached at any given time, when they are
lit continuously.
ECO mode
Attention! Your TESY electric water heater is of the highest energy class. The
class of the appliance is guaranteed only when it operates in ECO mode "Eco
Smart" due to the significant energy savings that are generated.
I n the ECO modes the electric water heater develops its own algorithm of operation
in order to guarantee energy saving, respectively to reduce your electricity bill, but to
maintain your maximum comfort of use.
This operating mode is especially suitable if you have established habits regarding hot
water consumption (for example, you shower at approximately the same time each day).
To operate the water heater in the "Eco" mode, press the  button until the ECO light
on the control panel appears. During the first week when the self-learning process of
the appliance based on the habits of the household takes place, the water is heated to
70 °C. After this period, the maximum temperature of water heating depends on the
actual needs.
Operation principle: When the Eco mode is selected the appliance will learn your
habits and develop a weekly program to provide you with the right amount of
water at the right time, but also so that it generates energy savings and lowers your
electricity bill. The principle of operation requires a self-learning period of one week,
after which the Eco mode automatically reproduces the learned cycle of work and
begins to accumulate energy savings without disturbing your comfort, calculated on
the basis of your habits. The appliance monitors your habits and learns constantly.
If you change your habits frequently, the appliance could not come up with a
completely accurate algorithm that guarantees your comfort and provides hot water
exactly when you need it.
Note: When the power supply goes out, the appliance saves the Smart algorithm
according to your habits for up to 45 minutes.

button again to switch the electronic control off. The
If you need to heat the water to a maximum temperature once, with the ECO mode
activated, select the maximum number of ''shower" symbol. With this change the ECO
algorithm is kept. Upon returning to the ECO mode, the operation of the water heater
continues based on the algorithm developed.
•
"Аnti-freezing" function
The anti-freeze function is active in the Stand By mode.
If you intend not to use the water heater for a long time, protect its contents from
freezing by pressing the  button to activate the "Anti-freeze" function, where by
the water heater will maintain the water temperature at approximately 10 °C.
WARNING: The electrical power supply of the device should be switched on. The
safety valve and the pipe connecting it to the device must be secured against
freezingter.
•
FACTORY SETTINGS RESET function
To enable this function, the appliance must be in Stand-by mode. You can enable it

and
by pressing and holding the
10 seconds you should hear two sound signals. The first one is a test, all symbols on
the display will be illuminated, and when you keep pressing the buttons you will hear
the second signal which will indicate that you have restored the factory settings of
the appliance.
WARNING: When you return to the factory settings, the smart algorithm is reset.
•
The "Anti-legionella" Function
The low temperature of the water in the water heater creates a favorable environment
for the development of microorganisms, and in particular the Legionella bacterium,
which can be extremely dangerous for the human body.
The Anti- Legionella / Disinfection Function is an innovative function and is
automatically activated in order to protect the water heater from the development
of bacteria in the hot water.
If the water in the water heater does not reach the temperature of 65 °C for 7 days, the
anti-legionella function is activated. The water in the water heater is warmed to 65 °C
and kept at this temperature for 60 minutes.

Problem log
When a problem is detected in the appliance, all symbols go out. The
lights up on the panel and starts flashing. At the same time, the appliance heater
switches off (the appliance stops heating) and the operating mode indication goes
out. Different errors are encoded with different number of flashes of the symbol
(flashes N times and goes out for 2 seconds).

PERIODIC MAINTENANCE

In the conditions of normal use of the water heater, under the influence of high
temperature, limestone (the so-called lime scale) deposits on the surface of the
heating element. This worsens the heat exchange between the heating element
and the water. The temperature on the surface of the heating element and around
it increases. Specific noise can be heard – of boiling water. The thermoregulator
begins to switch on and off more frequently. A "deceptive" activation of the thermal
protection is possible. Due to these facts, the manufacturer recommends preventive
maintenance of your water heater every two years by an authorized service centre
or service facility, this service remaining at the customer's expense. This preventive
maintenance should include cleaning and examination of the anode protector (for
water heaters with glass-ceramic coating), which has to be replaced with a new one,
if necessary.
To clean the appliance, use a damp cloth. Do not use abrasive or solvent-containing
detergents.
The manufacturer does not bear responsibility for any consequences arising
from non-adherence to these instructions.
Instructions for protection of the environment
Old electric appliances contain valuable materials and must not be
disposed of with the domestic waste! Please contribute actively for the
protection of the resources and the environment and dispose of the
appliance in the buy-back centres organized for this purpose (if such are
available).
