3.2 Main function
The control is a weather compensator with an outdoor temperature sensor that is fitted in the open air.
The control is connected to the outdoor temperature sensor
and the heat generator. The control controls the heating
installation and other connected components, e.g. the domestic hot water generation for a connected domestic hot
water cylinder or the ventilation of a connected ventilation
unit.
3.2.1 Heating
The outdoor temperature sensor measures the outdoor temperature and forwards the values to the control. When the
outside temperature is low, the controller increases the flow
temperature of the heating installation. If the outdoor temperature increases, the control reduces the flow temperature.
The control responds to the fluctuations in the outdoor temperature and uses the flow temperature to ensure that the
room temperature remains at the required temperature.
3.2.2 Cooling
The room temperature sensor measures the room temperature and sends the data to the controller. If the room temperature is higher than the desired temperature that is set, the
controller switches cooling on.
3.2.3 Ventilation
Using a controlled exchange of air, the ventilation unit ensures that the living rooms are ventilated and aerated. The
control controls the air volume flow via the ventilation levels
that are set.
4 Operation
6 Operating instructions multiMATIC 0020255037_00
3.2.4 Hot water generation
A temperature sensor measures the temperature of the water in the domestic hot water cylinder and forwards the values to the control. At a low domestic hot water temperature,
the control increases the temperature in the domestic hot
water circuit and thus heats the water in the domestic hot
water cylinder to the set domestic hot water temperature.
3.2.5 Circulation
If a circulation pump is installed in the heating installation,
the draw-off points will provide hot water more quickly. The
circulation pump pumps hot water through the secondary
return pipes in the circuit and to the draw-off points.
3.3 Zones
A building is divided into several zones if the heat demand
differs between different sections of the building.
– If underfloor heating and radiator heating are installed in
a house.
– If a house contains more than one independent residen-
tial unit.
If more than one zone is available, the controller controls the
available zones.
3.4 Hybrid manager
If you have connected a heat pump, the hybrid manager
attempts to cover the declared energy requirement under
the considerations of the cost optimisation and the technical
conditions.
Note
To ensure that the heat pump and the boiler can
work effectively and in synch with one another,
the tariffs (→ Page 15) must be set correctly. If
the tariffs are set incorrectly, this may result in
increased costs.
If the system declares an energy requirement, the hybrid
manager switches on and forwards the energy requirement
to the heat generator. The hybrid manager decides which
heat generator to operate based on the tariffs that are set in
relation to the energy requirement.
3.5 Frost protection function
The frost protection function protects the heating system and
apartment from frost damage. The frost protection function
monitors the outside temperature.
If the outside temperature
– falls below 4 °C, the controller switches the heat gener-
ator on after a frost protection delay time, and brings the
target room temperature to 5 °C.
– rises above 5 °C, the controller does not switch the heat
generator on but monitors the outside temperature.
Note
The competent person can set the frost protection
delay time.
3.6 Preventing malfunctions
▶ Ensure that air can circulate freely around the controller,
and that the controller is not covered by furniture, curtains or other objects.
▶ Ensure that all radiator valves in the room where the con-
troller is fitted are fully open.
3.7 Identification plate
The identification plate is located inside the product and is
not accessible from the outside.
3.8 Serial number
You can call up the serial number to the display under Menu
→ Information → Serial number. The 10-digit article number
is located in the second line.
3.9 CE label
The CE label shows that the products comply with the basic
requirements of the applicable directives as stated on the
identification plate.
The declaration of conformity can be viewed at the manufacturer's site.

failed and the controller enters limp home mode. The auxiliary heater now supplies the heating installation with heating
energy. During installation, the competent person has restricted the temperature for limp home mode. You can feel that
the hot water and heating are not becoming very hot.
While you wait for the competent person to come, you can
use the rotary knob to implement the following settings:
Inactive: The controller works in limp home mode; heating
and hot water at a moderately warm temperature
Heating: The auxiliary heater takes over heating mode; hot
heating, cold hot water
DHW: The auxiliary heater takes over domestic hot water
mode; hot water hot, heating cold
DHW+heat.: The auxiliary heater takes over heating and
domestic hot water mode; heating and hot water hot
Care 7
0020255037_00 multiMATIC Operating instructions 19
The auxiliary heater is not as efficient as the heat pump,
meaning that using only the auxiliary heater to generate heat
is expensive.
If you want to implement settings on the controller, click
Back and the basic display appears on the display. After five
minutes of no operation, the fault message appears again in
the display.

prestation. La mise en application de la garantie exclut tout
paiement de dommages et intérêts pour tout préjudice
généralement quelconque. Pour tout litige, sont seuls
compétents les tribunaux du district du siège social de notre
société. Pour garantir le bon fonctionnement des appareils
Vaillant sur long terme, et pour ne pas changer la situation
autorisée, il faut utiliser lors d’entretiens et dépannages
uniquement des pièces détachées de la marque Vaillant.
