System 3
System 3 consists of:
•
Burner
•
Heating circuit without mixer
•
2. Heater (e.g. solid fuel boiler)
•
Buffer storage
•
Water storage tank
•
Domestic hot water circulation pump
(Domestic hot water return pump)
The individual functions are activated by connecting the
appropriate sensor, i.e. the domestic hot water program is only
executed when the domestic hot water temperature sensor is
connected.
