Reloading intervals when operating with storage tank

Determining the right amount of fuel

Do not modify the factory settings!
Changing the system's factory settings can be detrimental to efficiency and
emissions of the system.
❒ Turn on the main switch
➥ There is voltage at all of the boiler's components
➥ When the control has completed the system start, the boiler is ready for
operation
Reloading intervals and amounts should be determined exclusively according to the
storage tank for efficient and environmentally-friendly heating.
❒ Check the store load status on the display
Load status
The amount of fuel added should allow the storage tank to be constantly heated to the
max. storage tank temperature (= boiler target temperature). Please note that the
amount to reload also depends on the type of fuel.
Example: Heat a 2000 litre storage tank by 30°C
The calculation below only takes into account the storage tank. It does not take into
account the boiler efficiency, pipe losses and the energy required to heat the boiler
and heating system.
Assumption: The storage tank currently has a temperature of 50°C and should be
heated to 80°C. The calculation below shows how much fuel is required for heating.
First we calculate the energy required:

NOTICE
No bars or one bar in the store load status means that the
storage tank needs to be heated up by approx. 35°C.
⇨ See "Determining the right amount of fuel" [page 24]
Two bars in the store load status mean that the storage tank
needs to be heated up by approx. 20°C.
⇨ See "Determining the right amount of fuel" [page 24]
Three or four bars in the store load status mean that the storage
tank cannot take any more heat, or only a small amount. In this
case do not add fuel!
