FUNCTION DESCRIPTION
The heater is designed for accumulation hot water using electricity. Water is heated by an electric element
in an enamelled thermally insulated tank. The unit is controlled by means of the control unit during heating
period. Turning of the round controller to the left and to the right enables switching between one and four
modes (see Table 1 below). The internal control unit includes intelligent thermostat SMART and receiver
HDO (Bulk remote control). It differentiates high and low tariff according to the code setting (see chapter
3.5 setting the receiver HDO). Information on high and low tariff can be used in modes MANUAL and
SMART. The user can select one of four operating modes specified in the table below.

In modes SMART, SMART HDO, MANUAL a MANUAL HDO it is possible to control with signal
HDO decoded with internal receiver. If the servicing interface is used (application for
Android or iOS) for activating receiver HDO, then modes SMART and MANUAL are replaced
with SMART HDO and MANUAL HDO.
Once the selected temperature is reached, heating interrupts automatically. Water accumulated in the tank
is then used for consumption. The tank keeps constant pressure of water from the water main. If the
combination faucet hot water valve is opened, water from the water supply conduit pressed out by cold
water pressure flows out of the heater. Hot water flows out through the top part, and inflowing water
remains in the bottom part of the heater.
