Operation manual 26
3.2.7.1 Auto Select - AUT button
The automatic selection of the system favours the operation of the heat pump. If necessary, a
bivalent source of thermal energy - electric heating rods - is attached.
3.2.7.2 heat pump - TČ button
With this option only the start of the heat pump is possible. The bivalent power supply (heating
rods) is blocked and is activated only in the event of a serious failure of the device.
3.2.7.3 Bivalent heater - BIV button
Only the operation of a bivalent source - heating rods - is allowed for heating.
3.2.7.4 Cooling - CHL button
In summer mode it is possible to start the cooling mode (if fitted). After pressing, a window
appears next to the value "Water temperature in the plate exchanger“ for the possibility of
entering the desired water temperature for cooling.
3.2.7.5 Off - OFF button
The whole system shuts down, including circulators. Sometimes, due to the set coastdown,
circulation pumps can still run max. 2 minutes after the heat pump is switched off.
3.2.8 Solar panel
To operate the solar panels, use the Solar window, which is activated by clicking the Solar
button located in the bottom bar of the main screen (Figure 9).
The solar circulation pump is running if the temperature of the solar panel
exceeds the temperature in the accumulation tank by at least 8°C. Stop if the
temperature of the solar cell exceeds the temperature in the accumulation
vessel by only 3 °C or less, or if the temperature in the accumulation vessel
exceeds 80 °C.
