14 Maintenance (and cleaning)
13.4 Buffer tank loading
Fig. 2-50
This menu
1
is only visible when a buffer control in the
boiler control is enabled.
In the event of good weather being forecast, the buffer
tank is charged for a shorter time within the time
release.
The bar
2
can be used to set the level of influence for
each buffer tank individually.
0% = if the burner has started and the buffer tank is
within a time release, the buffer tank is completely
charged. The charge request is fulfilled when the
buffer
temperature, lower,
has reached the
maximum buffer
temperature, lower
(in the buffer tank main menu).
100 % = if the burner has started and the buffer tank is
within a time release, the buffer tank is not completely
charged. The charge request is already fulfilled when
the
buffer temperature, lower,
has exceeded the
mini-
mum buffer temperature, upper
(in the buffer tank main
menu).
14 Maintenance (and cleaning)
i
Regular maintenance of the heating system is
a prerequisite
–
for permanently reliable functioning of the
boiler,
–
for energy-saving and environmentally fri-
endly operation of the boiler,
–
for a long service life of the boiler.
Basic information on boiler maintenance (including
cleaning activities):
–
Part of the boiler cleaning is done automatically in
the boiler
–
Some activities must be done manually.
On the following pages you will find an overview
of these manually required activities:
–
What activities have to be performed
–
At what time interval must this activity take place
–
Who is responsible for carrying out the respective
activity
Boiler cleaning - automated processes
The following processes are carried out automatically
by the boiler control at regular intervals:
–
Clean the turbulators
1
by rotating the inside of the
heat exchanger, whereupon the ash falls into the
combustion chamber
2
.
–
The ashes from the burnt pellets fall through the
stainless steel combustion grate
3
into the com-
bustion chamber. The ash roller
4
transports the
ashes into the ash container below (this ash con-
tainer must be emptied regularly).
