System 3
Turbotec wood gas boiler with
load compensation, buffer or
energy storage tank, tap water
storage tank, weather guided
heating circuit and tap water
control.
Functional description
System 3
If the heating is switched on on
the Turbotec,
- the remote indicator H1 goes
out.
- If the boiler temperature
reaches 50
C, the primary
pump P1 switches on and the
return temperature of the
Turbotec is raised via the return
valve Y1.
- From a boiler temperature of
55
C, the return valve Y1 opens
(the return temperature
continues to be raised) and heat
is discharged to the upper part of
the load compensation, buffer or
energy storage tank.
- Once the minimum
temperature has been reached
at the boiler sensor BS of the
heating circuit and tap water
control system, the charging of
the tap water storage tank takes
place according to the program
and heat is discharged to the
heating system.
- From a boiler temperature of
72
C, and depending on the
heat consumption and the target
boiler temperature that has been
set, the load compensation,
buffer or energy storage tank is
switched in and charged
accordingly.
- If the fuel is exhausted, the
heating is switched off. The
residual heat from the boiler is
fed into the load compensation,
buffer or energy storage tank
depending on the temperature
difference (between the boiler
temperature and the storage
tank temperature). Once the
boiler temperature has fallen
below the minimum value Tkmin
(can be set in the installer
menu), the withdrawal of heat
from the boiler is ended.
- The stored heat can now be
discharged to the heating
system or the tap water storage
tank, as required.
- Once the temperature in the
load compensation, buffer or
energy storage tank falls below
the minimum value TSmin (can
be set in the installer menu), the
remote indicator H1 lights up.
- Once the temperature at the
boiler sensor BS of the heating
circuit and tap water control
system falls below the minimum
value, the discharge of heat to
the heating system or tap water
storage tank is ended.
Important instruction:
The setting of a
boiler
temperature TK S of 85
C
causes the load
compensation, buffer or
energy storage tank to be
charged at the same time as
heat is discharged to the
heating system.
The storage charging valve Y2
begins to open from a boiler
temperature TK I of 72 °C. In
other words, the boiler output is
only reduced after the load
compensation, buffer or energy
storage tank has been charged.
The setting of a
boiler
temperature TK S of 70
C
causes the load
compensation, buffer or
energy storage tank to be
charged only after the
produced boiler output is no
longer consumed by the
heating system.
The boiler
temperature will therefore
continue to increase and the
storage charging valve Y2
begins to open from a boiler
temperature TK I of 72 °C. In
other words, the boiler output is
reduced before the load
compensation, buffer or energy
storage tank has been charged.
