EC2

 - ECO NIGHT (SMART algorithm with night-time heating priority).

The selected mode is displayed on the screen.

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.

In the "ECO" mode, the water heater produces its own algorithm to ensure 
energy savings, respectively, to reduce your electricity bill, but to maintain 
maximum comfort in use.
Principle of operation: after selecting one of the three Eco Smart modes, the 
appliance will learn your habits and it will elaborate a weekly programme so 
as to provide the necessary quantity of water in the respective time when you 
need it and at the same time to save energy and thus to reduce your electricity 
bill. This principle of operation requires a period of self-training which lasts a 
week, and after that the Eco Smart mode begins to accumulate energy savings 
without disturbing your comfort calculated on the basis of your studied habits. 
The appliance continuously monitors your habits and continuously gets self-
trained.

In this mode it is impossible for you to intervene after it has been selected.
In case you often change your habits, the appliance will not be able to 

elaborate an exact algorithm which to guarantee your comfort and to provide 

you with hot water exactly when you need it. In this sense, if the operation of 

the appliance in Eco Smart mode does not satisfy you and does not provide 
you with the required comfort, and at the same time you want the appliance 
to keep reducing your costs, by pressing the button 

 you can select 

EC1

mode of operation – for higher level of comfort which again guarantees energy 
saving, but to a lower extent. 

EC1

 mode of operation is intended for users with 

frequently changing habits for whom an exact schedule of weekly operation 
would be difficult to establish. 
To generate maximum energy savings, you can select the 

EC2

 mode. This is a 

SMART algorithm mode with overnight heating priority.

Note: When the power is turned off or off, the appliance keeps the settings for 

up to 12 hours. You can restart the algorithm only by the On/Off button, and 

the appliance will begin its self-training again.

"LOCK" function

By holding buttons  

+ 

  simultaneously, the control panel locks itself and 

no commands may be given through it. If the panel is locked, the 

 symbol 

is visualized on the display. If you press a certain symbol while the panel is 
locked, all buttons light up but the appliance does not accept commands and 
the 

  symbol flashes 3 times, prompting for unlocking. To unlock the panel 

once again, you need to press and hold buttons  

+ 

  simultaneously for 

2 seconds. 

•

"Vacation" mode

If you plan to be away from home for more than a day, you can enable the 
Vacation mode, so that the electric water heater will “know” when you will be 
back to provide you with hot water.
To turn the Vacation mode on, you need to press button  

. The display 

visualizes „00“ days and the digits and   symbol 

are flashing. If the “00” 

number of days is not changed, the Vacation mode cannot be activated. 
To introduce the number of days, use the 

  button. If you touch it once, the 

counter value is increased by one. If you press and hold the button, the counter 
value increases automatically at a higher pace. The maximum number of days 
you can set, is 90. The 

  symbol is still blinking. The other two parameters 

are set as default settings: maximum number of showers at 18:00 on the last 
vacation day. 
To change the time, at which you will need the desired amount of hot water, 
use the 

   button. To change the number of showers, use the  

 button.

The parameters set are confirmed by pressing the 

 button, thus activating 

the Vacation mode. On the display the 

  symbol stops blinking and is lit 

constantly. The number of vacation days, the number of showers and the time 
when hot water needs to be available, are visualized. 
To exit the vacation mode without changes, you may either press  

 or, if you 

do not touch any button for a long time. The  

  symbol disappears.

To exit the Vacation mode, press any of the following buttons: 

,  

 or 

 . If you press   

, while the Vacation mode is activated, you enter the 

programming mode and the number of days and the  

 symbol start blinking 

again.

The number of days that you enter (the period of your absence) must 

include the day on which you will be coming back home.

•

"BOOST" function 

(a one-time heating up to maximum temperature and 

automatic return to the already selected mode of operation)

When the BOOST function is enabled the water heater will heat the water up to 
max °C without changing the algorithm of operation of the respective mode of 

operation. When the maximum temperature has been reached the appliance 
automatically switches to the previously selected mode of operation. The 
BOOST function is active with the following modes: Eco Smart, Vacation and 
Weekly Programmer.
To enable the BOOST function, press continuously (for about 3 seconds) the 

.

To deactivate BOOST, hold the 

  button once again.

•

"RESTORE FACTORY SETTINGS" function

To enable this function, the appliance must be in Stand-by mode. You can 

enable it by pressing and holding the 

 button for at least 10 seconds.  All 

symbols on the display will be illuminated which will indicate that you have 

restored the factory settings of the appliance.

•

"Shower" symbol

The Handset symbol 

  provides you with information on the amount of 

hot water that has already been heated and whether the amount set has been 

reached in the different modes. The amount of water per shower is calculated 

on the basis of the average European standards and it may not coincide with 

your personal comfort. 
When the "Handset" symbol is lit constantly, it means that the set amount of 

hot water is reached. When the "Handset" symbol flashes, this indicates that the 

appliance is in a warm-up mode. When more than one "showers" are not ready, 

they flicker one after another continuously. Thus you obtain information about 

the set amount of hot water and the amount reached at any given time. 

Example

:

Hot water for 2 showers is ready to use. The third shower is in the process of heating. 

The final objective is to have hot water equivalent to 3 showers.

In the “Manual control” mode and the “BOOST” mode the screen visualizes a 

timer counting the estimate time remaining until the set amount of hot water 

is reached.

VII. 

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).
