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
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-
Factory setting
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
