2.5.2 - Heating fluid heating in a thermal store
Fill the heating system with heat transfer fluid, airbleed it and pressurize to the working pressure. Set the de-
sired temperature via the solar controller.
2.5.3 - Heating element state during operation
When the safety temperature is reached, the safety thermostat will cut off the heating element from power
supply. The safety thermostat features no automatic reset. After the tank cools down to below 40 °C, unscrew
the lid of the heating element and reset it by pressing the button. The heating element is ready again.
2.5.4 - Possible faults
If the tank gets overheated without any other heat source used (the solar controller probably does not turn off
the heating element when the set temperature is reached), call your service provider.
If the heating element shows signs of another defect, disconnect it from the mains immediately and call your
service provider.
2.5.1 - DHW heating in a hot water storage tank
In order to heat water in the hot water storage tank, open the cold water inlet, fill the tank with water and air-
bleed it by opening the hot water tap. Set the desired temperature via the solar controller.
It is recommended to set the temperature to 60 °C. This temperature guarantees the best operation of the
heating element, offering also:
- protection against Legionella
- cost reduction
- slower deposit formation
