Press and hold the button F to access the setup modes.
This menu and the next two menus are not used and are passed by with brief presses of
button F until the display shows information about the time of switching on and the
temperature set.
Using the buttons ▲, ▼ and Г shall enable you to select up to two water heater operation
periods for a specified period of time. By pressing button F you save the specified settings
and the first scheduled period begins.
If the settings on both boxes in the left down corner of the periods of time are empty or
unchanged, after pressing F the unit enters in normal mode Heating and the mode Heating
timer does not appear in subsequent switching of the unit between modes.
Mode Delayed start
This mode allows a single switching on of the unit in operation at a specific time. When the
unit reaches predetermined time of the date set it switches to normal mode Heat.
You may set time and date for switching on by any other modes by pressing and holding the
button F.
Using the buttons ▲, ▼ and Г you may select time and date for unit switch on in mode
Heating. With subsequent pressing the F button the settings are saved and when the
display shows the image of following illustration the unit operates in Delayed start mode.
The display shows the time and date of switching on, the water temperature, current time
and temperature set to heat the water.
Switch off the unit in any operation mode
You can switch off the unit from any operation mode by pressing repeatedly button F, passing through the operating
conditions until reaching switch off state.
Corrosion protection
In tanks with enameled coating is activated the electronic control block option to follow-up
operation with embedded safety anode. In switched off-state and during unit operation in
any operating mode, on the left side of the display is shown the anode protection operation.
The presence of horizontal solid lines means that the anode is in good condition and
protects the tank enamel coating. The anode is a wear and tear part of your appliance.
Filling of the display to full height depends on the anode capacity, but as well of the
temperature, composition, hardness, electric conductivity and other water parameters. When the anode is worn or
for any reason disconnected from the water tank, at the top of the display shall appear the message Anode Low.
Should this message appear on your unit display it is necessary that you immediately contact the nearest
authorized by the manufacturer or vendor service company to check the anode protection, and if necessary, to
replace the anode .
WARNING! Operation of the water heater with a damaged or worn anode or impaired anode protection is
unacceptable because it reduces the corrosion resistance of enameled tank.
In tanks of chrome-nickel steel the anode is not embedded for protection against corrosion because of the steel
properties. In this case the anode function of the electronic control block is factory deactivated.
Antifreeze function
In the electronic control block is integrated an additional function that monitors water temperature even when the
unit is disconnected or switched off. This function allows the water heater to turn on when the water in the tank drops
