1.3 DESIGN AND GENERAL HEATER DIMENSIONS The heater tank is made of a steel plate and tested by 0.9 MPa overpressure. The inside of the tank is enamelled. A flange is welded onto the bottom of the tank with a flange lid screwed to it. A sealing ring is inserted between the flange lid and the flange.
2 OPERATION AND FITTING INSTRUCTIONS 2.1 OPERATING CONDITIONS The tank shall only be used in accordance with the conditions specified on the power plate and in instructions for electric wiring. Besides legally acknowledged national regulations and standards, also conditions for connection defined in local electric and water works have to be adhered to, as well as the installation and operation manual.
If the hot water heater is mounted in a tight, small space, or in an intermediate ceiling, etc., you have to make sure that the connecting side of the appliance (connections to water supply, area for electric plugging) remained accessible and no heat accumulation occurs. Free space of up to 500 mm from the bottom edge of the heater has to be available under the heater.
Required pressures - Table 4. We recommend that the hot water distribution from the heater was as short as possible to minimise heat losses. U - Closure Allowable Maximum operational P - Safety valve with Start-up pressure in the backflow valve overpressure pressure of the cold water...
Ø10 Ø8 Ø8 Ø10 Figure 5 It is necessary to observe the below requirements during the electric wiring. Heater is connected to power supply 1 PEN AC 230V/50Hz via a fixed movable wire/wires (depending on the connection method). The circuit must contain a breaker disconnecting all poles of the network, and a circuit breaker (protector).
The terminals of L, N, PE (230V/50Hz) supply include factory connected flexible plug with length 2,5m connectable to the standardized plug EU. After the cover opening electrical wiring can be disconnected using flexible plug and connect the conductors into the cross-section up to 2.5 mm 2.5 FIRST HEATER COMMISSIONING Before opening the power supply, the tank must be filled with water.
Drainage of service water shall be performed after closing the shut-off valve in the cold water supply piping (through the discharge valve for safety valve combination), and with simultaneous opening of all hot water valves of connected fittings. Hot water may outflow during the drainage! If there is a risk of frost it has to be considered that not only the water in the hot water heater and in the hot water piping may get frozen but also the water in the entire cold water supply piping.
3.1 OPERATING MODES AND THEIR SYMBOLS Figure 7 - Round controller 3.1.1 SMART MODE In this mode the controller passes through two phases in order to save at least 10% of electric power, comparing to the MANUAL mode. In the first phase in one calendar week the constant temperature of the heater 65°C is maintained, and the control electronics monitors the user's behaviour in terms of water consumption.
3.1.2 SMART HDO MODE The thermostat monitors the signal HDO and saves its weekly history. SMART HDO mode operates identical to SMART with the extension; based on saved history of HDO it assumes the high tariff periods when heating is not possible. It starts automatically heating the boiler in advance in order to have available required amount of hot water for the user consumption as recorded in the history of SMART mode consumptions.
3.2 THERMOSTAT CONTROL The heater control is possible by means of round controller clockwise and anticlockwise or by means of the application control on the device with Android and iOS (more info in chapter software for mobile devices). 3.2.1 LED DISPLAY The front side of the heater includes the four digit seven segment LED display, additionally to the heater.
The controller central part includes the symbols below: Symbol Colour Brief description SMART white SMART mode indication MANUAL white MANUAL mode indication ECO stop indication (MANUAL mode with set OPTIMUM green temperature 55°C) PROG white PROG mode indication The light is on at the time of low tariff if the mode green is on HDO ANTI-FREEZE...
3.5 SETTING HDO (BULK REMOTE CONTROL) Smart heater includes HDO receiver (bulk remote control). Correct function requires setting the HDO parameters by means of mobile application in the setting section. The setting parameters HDO are detailed in Table 7. To find out the presetting (A, B, DP (P)) and the frequency, it is necessary to open the main home cabinet (place with electricity meter and receiver of HDO signal), with specified code for the consumption location, ideally in the form of the presetting (A, B, DP (P)) + frequency.
Page 21
Another option is that the HDO receiver includes a different code, e.g. A85. This code must be entered in the electricity distributor web pages, where after entering and subsequent conformation, the code is A1B8DP5 displayed in required form. i.e. specifically in A85 and the supplier ČEZ , the code is displayed .
3.6 CONTROLS DESCRIPTION 3.6.1 MODE CHANGE WITH CONTROLLER Setting the thermostat mode is performed by turning the controller. In case of turning clockwise and anticlockwise, the functions are gradually switched: ANTI-FREEZE, SMART, PROG, MANUAL. Each controller step changes the function to the next or changes temperature during mode MANUAL by 1°C. 3.6.2 BASIC DISPLAY In all modes during common operation the display contains the actual water temperature in the in the...
3.6.5 FAILURE STATE In case of the defect detected by thermostat, the display shows the defect code: The error codes required by the client are specified in the table below. Failure code Status description Er01 Excessive wear of anode (anode voltage is lower than the limit) Er02 upper temperature sensor defect Er03...

4.1.5 VACATION SECTION Section for setting the period when the heater is in mode „ANTI-FREEZE“. The displayed calendar in this case is used only for the vacation deadline visualisation, and it has no further function. Information on the ongoing vacation is visibly specified in the status information in the main signpost during the height mode, or on the left panel in the width mode.
Figure 15: Statistics screen 4.1.7 SETTING SECTION This section enables to additionally synchronize the boiler time, unless it was completed after starting the application, and it is possible to activate or deactivate the HDO function. It is possible to set the name of the connected boiler which is suitable in situation the user owns more SMART heaters and it is necessary to differentiate them simply.
The application is designed for the servicing technicians and contains additional servicing settings which enable to configure the boiler volume or HDO parameters. Figure 17: Setting screen (HDO) 4.1.8 INFO AND TIPS The section contains information on SMART technology with the definition of the main functions and smart boiler modes.
5 IMPORTANT NOTICES 5.1 INSTALLATION REGULATIONS Without a confirmation of performed electrical installation issued by an authorised company, the warranty certificate shall be void. Check and exchange the Mg anode regularly. You have to apply for approval of a local power supplier to connect the heater. No stop valves can be put between the heater and the safety valve.
