9.8 Parameters which can only be set with
vrDIALOG
Settings via vrDIALOG must only be undertaken by an
approved heating engineer.
Parameters Description Factory setting
Calibration of temperature sensors Internal sensors (T1, T3, T5, T6 and T8) can only be
calibrated via vrDIALOG 810/2.
Change name: Heating circuit Change name: You can name each heating circuit in
the heating system individually. A maximum of
ten letters are available per heating circuit for
this purpose. The selected names are saved
automatically and displayed on the correspond-

Depending on the system configuration, the names of
additional heating circuits appear in the display.
HK2: HK2
Software version The status provides information on the operating con-
dition of the heat pump software. —
Elec Tariff switch Elec Tariff switch: Elec Tariff switch status by actuat-
ing the energy supplier contact (cut-off time by
power supply operator):
"no" = no cut-off time,
"yes" = cut-off time active,
actuation e. g. via ripple control receiver/ripple
control signal.
—
Phase Status Phase Status: displays whether all 3 phases are
present (OK/Error).
—
Phase Sequence Phase Sequence: The display shows whether the
rotating field direction is correct
(OK/error).
—
Minimum flow temp.
Maximum flow temp. Minimum flow temp./Maximum flow temp.:
Setting the limiting temperatures (min. and max.) that
the heating circuit can request.
The maximum flow temperature is also used to calcu-
late the value for the underfloor protection circuit
(maximum CH tempe compressor hyst
2K).
15 °C
43 °C
Pre-loading time Pre-loading time:
To take account of the inertia of the underfloor
heating, you can manually set a pre-heat before
the start of the programmed heating time.
