Periodic Maintenance - TESY GCV 504716D C22 ECW Manuel D'utilisation

The ⯈ button selects the operating mode. You can choose one of the four
modes: 45 °C, 60 °C, ECO or 75 °C.
Each time you press the button, a mode is selected from the following
sequence: from 45 °C, 60 °C, ECO or 75 °C as follows:
45°C 60°C
45 °C modes
In this mode, the appliance will heat the water to a temperature of
approximately 45 °C.
On the control panel, the indicator light provides feedback on the
selection made. During the heating process the first sector of the light bar
flashes. When the set temperature is reached, the bar sector is constantly
illuminated.
60 °C modes
In this mode the appliance will heat the water to a temperature of
approximately 60 °C.
On the control panel, the indicator light provides feedback on the
selection made. During the heating process the first and the second sector
of the light bar flash. When the water is heated to 45 °C, the first sector
is constantly illuminated and the second sector of the bar continues to
flash. When the set temperature (60 °C) is reached, both sectors of the bar
will be constantly illuminated.
75 °C modes
In this mode the appliance will heat the water to a temperature of
approximately 75 °C.
On the control panel, the indicator light provides feedback on the
selection made. During the heating process the first, the second and the
third sector of the light bar flash. When the water is heated to 45 °C, the
first sector is constantly illuminated and the second and third sectors of
the bar continue to flash. When the water is heated to 60 °C, the second
sector is constantly illuminated and the third sector of the bar continues
to flash. When the set temperature (75 °C) is reached, the whole bar is
constantly illuminated.
ECO modes (self-learning mode)
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.
During heating the entire light bar flashes. When the water is heated to
45 °C, the first sector is constantly illuminated and the second and third
sectors of the bar continue to flash. When the water is heated to 60 °C,
the second sector is constantly illuminated and the third sector of the bar
continues to flash. Upon reaching a temperature of 70 °C, the whole bar
lights up constantly.
In 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.
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.
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 its settings
for up to 12 hours.
If you need to heat the water to a maximum temperature once, with the
ECO mode activated, select the 75 °C mode. 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.

The Anti-freeze 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, whereby the water heater will maintain the water temperature
at approximately 10 °C.
The power supply of the appliance must be switched on. The safety
valve and the pipeline from it to the appliance compulsory must
be secured against frost.
•
FACTORY SETTINGS RESET function
To enable this function, the appliance must be in Stand-by mode. You
can enable it by pressing and holding the "+ ⯈" buttons for at least 10
seconds. During these 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.
•
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.
4. Registered errors
⚠
When a problem is detected in the appliance, all symbols go out. The
symbol 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).
List of errors and their codes:
Error code
/ /
number of flashes
1 Error 1 The lower sensor is disconnected
2 Error 2 Short circuit of the lower sensor
3 Error 3 The upper sensor is disconnected
4 Error 4 Short circuit of the upper sensor
5 Error 5 The water heater is turned on without any water present
6 Error 6 Date and time setting
Attention! When the power is turned off for more than a 2 hours,
the appliance detects "Error 6". You need to find the aerial wireless
network of the water heater: "TCHxxxxxxxx" and to connect to it.
Note: If you see any of the above listed errors, please contact an
authorized service centre. You can find a list of them in the warranty
card.

PERIODIC MAINTENANCE

VIII.
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).
