Parameters
Switch-on room temp.
>None
Remote control YES 23 °C
>Select mode
Only when VR 90 remote control is used:
Switch-on room temp.:
None = Room temperature from remote control is not
taken into consideration during heating mode.
The room temperature measured has no influ-
ence on cooling.
Switch on = In addition to the set heating curve, the
heating flow temperature is influenced depend-
ing on the difference between the room target
and actual temperature.
Thermostat = Room temperature from VR 90 is used
directly for control (function of a room thermo-
stat) The set heating curve is shifted. Heating is
stopped as soon as the desired room tempera-
ture is exceeded by more than 1K. Heating is re-
enabled when the temperature falls below the
target room temperature.
i
Select this setting if you have set energy
balance control.
Cooling (only if external passive cooling is
installed): If the room temperature exceeds >
RT_target (day) + 3K, cooling is requested. The
essential requirement for a cooling request
based on the room temperature is that the 24 hr
outside temperature mean value is sufficiently
high (less than 5K below the cooling start limit
for the outside temperature-dependent cooling
request).
Remote control: Automatically indicates whether a
VR 90 remote control unit is connected (YES/
NO). If YES, the room temperature measured at
the VR 90 is also displayed.
This menu may appear repeatedly (for every heating
circuit with remote control).
