| OPTIONS FOR SWITCHING ON ADDITIONAL ENERGY SOURCES | | | | |
The controller features the option of an auxiliary source for heating the water to the minimum temperature
| | | | |
The option for starting the primary energy source immediately or only when the water cannot be heated in a certain period of time
| — | | | |
The option for configuring the time during which we allow water heating only by using collectors – the controller will not switch on the primary heat source if the calculations show that the water can be heated only by collectors

| OPERATING MODES WITH MULTIPLE HOT WATER BUFFER TANKS | | | | |
| Constant operation in the “OPTIMUM” mode means an optimum use of solar energy for heating all of the storage tanks taking into account the preferred storage tank | — | | | |
| The "AUTO" operation mode automatically switches between winter and summer modes according to a preset calendar | — | | | |
| Constant operation in the “SUMMER” mode means the heating of only the preferred storage tank, other storage tanks are heated only when the preferred one reaches the desired temperature | — | | | |
| Continuous operation in the “WINTER” mode means an alternating parallel heating of all storage tanks | — | | | |
| Heating of all storage tanks | — | | | |
