[. . . ] Insert the sensor into the channel: - if you insert the sensor higher in the channel, the thermostat will react too fast, the operating time of the circular pump will be shorter and the difference between the temperature in the hot water tank and heating media after the thermostat switch off will be higher. cHILDREN SHOULD BE SUPERVISED TO ENSURE THAT THEY DO NOT PLAY WITH THE APPLIANCE. This means that the quantity of water in the hot water tank and its temperature will be slightly higher. 5 EN CONNECTION TO THE WATER SUPPLY EN Connection to water supply should be made according to the markings for the connections, as defined in the previous chapter. [. . . ] It must be led into the sewage by means of a flexible condensate drainpipe ø16 mm on the backside of the heat pump. 9 EN OPERATION OF THE HEATING PUMP EN After the water tank with heating pump is connected to water supply (heating) network and filled with water, the heating pump is connected to power supply network and ready for operation. The appliance should be connected to the power supply network in compliance with the national installation regulations.

The heating pump starts operating and operates until the switch-off temperature is reached (factory set to 55 °C). After switching off, the operation is interrupted until the water temperature falls by 5 °C (e. Legend: 1 - Heat pump switch on 2 - Legionella Control switch on 3 - Control lamp - heat pump operation 4 - Control lamp - Legionella Control switch on 5 - Display 6 - Temperature setting - increase 7 - Temperature setting - reduce After connecting the heat pump to power supply, the display shows servicing markings and then the temperature value. If the water temperature in the hot water tank is lower, the heat pump is automatically switched on (the red signal lamp 3 is on). The operation of the heat pump is switched off; the display shows the marking OFF. The display shows the current water temperature in the hot water tank, the signal lamp 3 switches on. With key 7 the temperature is reduced and with key 6 the temperature is increased. When the setting is completed, the marking on the display starts flashing. After eight flashes the new temperature is set, and the display shows the temperature of the water in the hot water tank. WARNING: If the heating pump is operating outside the temperature zone of operation, the evaporator may freeze. Then, the heating pump switches off, and the display shows the marking tLo. After switching off the heating pump will remain inoperational until the evaporator unfreezes. This system includes a special function for high temperature heating (up to 65 °C) of water in the hot water tank. The system operates automatically, switching on the high temperature heating of water every 14 days. When the temperature in the water tank reaches 65 °C, the high temperature heating is switched off. High temperature heating can also be activated manually, by pressing the key 2 (ca. The display alternatively shows the temperature of water in the hot water tank and marking LEG. When the temperature in the hot water tank reaches 65 °C, the heat pump is switched to normal operation. [. . . ] The build-up of calcium and lime in the hot water tank depends on the quality, quantity and temperature of water flowing through the heating pump. The maintenance service provider shall also prepare a status report and consequently recommend the date of the next inspection. In spite of monitored manufacture and final control, it may happen that failure occur during the operation of the heating pump. Before calling your service provider, check the following: - Is everything OK with the power supply network? [. . . ]
