The
∆
T circ adjustment value can be used to com-
pensate the temperature loss in the circulation pipe.
When the switching condition for a function is ful-
fi lled at the VFD sensor (T-CW), the
∆
T circ value
determines the temperature loss value that is to be
calculated into the control logic in order to ensure
that the switching condition can be met.
Î
Read the correct value for
∆
T circ from the ta-
ble below.
During thermal disinfection, the parameters
T-circ therm
and
T-HW
set
are blocked against
each other by
∆
TCirc + 2K
in order to ensure that
the switch-off temperature
T-circ therm
can be
reached at the reference sensor.
During thermal disinfection, the set temperature for
the HW fl ow sensor is increased by
∆
T circ for the
stabilisation phase, in order to ensure that the disin-
fection temperature can also be reached at the VFD.
Note:
The
∆
T circ
value has to be adapted to the
individual system and must thus be adjusted
by specialised craftsmen only.
