Vaillant VR 71 - 2.14.2 Menu item INFORMATION

0020288151_04 Operating and installation instructions 11
Air quality limit: ppm The ventilation unit keeps the CO
2
content in the room air below
the set value.
Ventilation boost Heating mode is switched off for 30 minutes and, if available, the
ventilation unit runs at the highest ventilation level.
Humidity prevention When the Max. room air humidity: %rel is exceeded, the dehu-
midifier switches on. If the value is not reached, the dehumidifier
switches off.
Max. room air humidity: %rel Target value for the humidity prevention function
Time programme assistant Programming of the desired temperature for Monday–Friday and
Saturday–Sunday; the programming applies for the time-controlled
Heating Cooling, DHW, Circulation and Ventilation functions
Overwrites the weekly planner for the Heating, Cooling, DHW,
Circulation and Ventilation functions
Green iQ: Switching on the most energy-efficient heating mode, if your install-
ation supports this.
Installation off Installation is switched off. Frost protection and, if available, ventil-
ation remain activated at the lowest level.

INFORMATION
Ext. power reduction: Display whether a signal from the energy supply company about
the power reduction for your installation is active, inactive or not
available.
Ext. energy manager status: Active means: The external Energy Manager has taken over the
control. The system control displays a reduced selection of func-
tions.
Current temperatures
Zone Current room temperature in the zone
DHW temperature Current temperature in the domestic hot water cylinder
DHW circuit 1 Current temperature in domestic hot water cylinder circuit 1
Water pressure: bar Current water pressure in the heating installation
Current room air humidity Current room air humidity, measured using the installed humidity
sensor
Energy data Display of the energy consumption, energy yields and efficiencies
App, boiler and system control display estimated values for energy
consumption, energy yields and efficiencies based on an extrapol-
ation. The displayed values in the app may differ based on the dif-
ferent update intervals when compared to the displays in the con-
trol panels for the boilers and system control.
Among other things, the values depend on:
– Installation and type of heating installation
– User behaviour
– Seasonal influences
– Tolerances and components
External consumers and generators in the household (e.g. ext.
heating pumps or valves) are not taken into consideration.
Deviations between the displayed values and the actual values
may be considerable; the specifications are therefore not suitable
to be used to create or compare energy billing.
Solar yield Energy yield of the connected solar system
Environmental yield Energy yield of the heat source installation for the connected heat
pumps
Power consumption The installation's electrical energy consumption based on the re-
spective system function and/or the overall installation
