5.1.2.2 Installation with storage tank
If this type of installation is selected, it is the temperature in the storage tank that determines when the
burner starts up, and when the burner is in standby.
The storage tank functions in principle as an extension of the boiler volume. When the storage tank sensor
(extra sensor has been selected to function as a storage tank sensor – under “Extra sensor” in the ”Service
menu”) measures a temperature that is less than the end set point for the boiler temperature minus the
storage tank hysteresis (under the User menu if the storage tank function is selected in the ”Service menu”)
the burner starts.
Example:
The set point for the boiler temperature has been set to: 70 °C
The hysteresis for the storage tank has been set to: 15 °C
The Scandpell unit starts up when the temperature in the storage tank (measured by extra sensor) reaches
(70-15) = 55 °C
The Scandpell stops again once the boiler temperature has reached 70 °C.
Depending on how low down in the storage tank the return line to the boiler is located, and where the
extra sensor in the storage tank is located, the entire storage tank will be heated through – and therefore
the same temperature as the boiler. This requires sufficient flow in the system, so that all the energy
produced in the boiler is transferred to the storage tank – otherwise the burner stops when max. boiler
temperature is reached.
The pump must be set to be boiler pump and operate as long as the burner will not be in standby
or manually stopped. Thus the pump stops when the burner is in standby.
With the storage tank the set point for the boiler temperature is decided by the set value for max.
boiler temperature: Factory setting = 85 °C and the hysteresis is 10 °C.
5.1.2.3 Installation with a hot water tank
If it is decided to use the external sensor as a temperature sensor in a hot water tank, the control unit will
be able to start and stop a filling pump for the tank.
This filling pump starts up once the temperature measured by the extra sensor that is located in the tank
measures a temperature that is lower than the set point temperature minus the hot water hysteresis (Set
point temperature and hysteresis can be found in ”User Menu” under ”Hot water”).
Example:
Set point temperature: 55 °C
Hysteresis: 5 °C
The pump starts up when the temperature in the tank is lower than 50 °C and stops again when the
temperature in the tank is over 55 °C.
