3 Product description
This product is a domestic ventilation unit.
3.1 Role and function
Task
The product aerates and ventilates living spaces and ensures a constant exchange of air with heat recovery in the
building.
Furthermore, the product guarantees the hygienically necessary minimum air exchange and prevents damage to the
building caused by moisture and mould.
Functionality
1
23
4
5
The product (5) is the central component in controlled room
ventilation. Fresh outside air (4) is guided to the living rooms
and bedrooms via air intake openings (2). The used air from
the kitchen, bathroom and WC is guided outside (1) via the
exhaust air openings (3).
4
3
2
1
The exhaust air (2) from the dwelling is guided to the
product. The filter for the exhaust air cleans the exhaust
air and guides the exhaust air to the heat exchanger. The
heat exchanger extracts the heat from the exhaust air (heat
recovery). The cooled air is guided outside as exit air (4).
The outside air (1) is guided to the product from the outside.
The filter for the outside air cleans the outside air and guides
the outside air to the heat exchanger. The heat exchanger
transfers the heat from the exhaust air to the outside air. The
heated air is guided to the dwelling as supply air (3).
On summer nights, the outside temperature is often lower
than the room temperature. Through the automatic bypass,
the cooler outside air is no longer preheated by the heat exchanger. The bypass guides the warmer exhaust air past the
heat exchanger directly outside. The frost protection function
reduces the supply air volume flow according to demand,
which leads to an increase in the exit air temperature. This
prevents the heat exchanger from freezing. If the reduction in
the supply air volume flow is no longer sufficient, the product
switches off.
The humidity sensor records the current moisture in the
exhaust air. If you operate the product in auto mode, the
current air volume flow is regulated according to demand
(aguaCARE.
3 Product description
6 Operating instructions recoVAIR 0020159950_07
In the winter, the room air humidity can be perceived as
dry. The optional enthalpy heat exchanger (heat exchanger
with moisture recovery) has the opposite effect (aguaCARE
plus).

B Ventilation levels – Overview
Ventilation
level
Meaning
Automatic
ventilation
(recommended)
The relative humidity in the extract air is continuously measured and the volume flow is
adapted to the current requirement. This setting can be used throughout the entire year.
Nominal ventilation
The nominal ventilation is the normal operating mode at normal loading of the room air
and a normal number of people.
Reduced ventilation
Reduced ventilation should be selected if you
will be absent for an extended period of time
in order to reduce the energy consumption.
Increased
ventilation
Increased ventilation should be selected
for increased loading of the room air. For
example, if there is an increased number of
people or for activities such as cooking, etc.
Ventilation
boost (can only
be set using
the control
elements on
the product or
the control)
Ventilation boost should be selected if there is
temporarily increased load. Ventilation boost
is activated for 30 minutes, after which the
product automatically switches back to the
operating mode that was previously set.
C Status messages – Overview
Statuscode Meaning
S.800 Frost prot. element active
The frost protection element is activated at outside temperatures below −3 °C in order to prevent the
product from freezing.
S.802 Heat recovery active The bypass is closed. Heat is recovered via the heat exchanger.
S.803 Heat recovery not active
The bypass is open. The rooms are passively cooled.
S.804 Heat recovery 50% The bypass is half-open. The rooms are also passively cooled. However, part of the volume flow is
guided through the heat exchanger in order to prevent supply air being too cool.
S.805 Automatic mode The ventilation of the rooms depends on the moisture in the rooms. The more moisture there is, the
more intensive the ventilation. If the optional CO2sensors (carbon dioxide) are installed, the CO2content is taken into consideration.
S.806 Manual mode The product is operated at the selected ventilation level. This is set using the control elements on the
product, the step switch or an optional control.
S.807 Intens. ventilation Intensive ventilation has been activated.
S.808 Calibration Calibration mode has been activated.
S.809 Check programme or
sensor/actuator test active
A check programme or sensor/actuator test has been activated.
S.810 Days away from home
active
Days away from home mode has been activated.
S.811 Moisture protection
active
The moisture protection function has been activated. This is sometimes activated by functions of the
limp home mode.
S.812 Standard frost prot.
active
The standard frost protection function has been activated. The supply air ventilator is down-regulated,
depending on the outside temperature, in order to prevent the product from freezing.
S.813 Cut-off protection bypass active
The automatic bypass cut-off protection has been activated.
S.814 Intensive ventilation
overrun
A phase with nominal ventilation always follows an intensive ventilation phase.
S.815 System off Frost protection active
The product is switched off at low temperatures in order to prevent the product from freezing.

product then starts normal operation.
Supply air temp.: > 10 ℃
F Troubleshooting and fault elimination
F.1 Troubleshooting
Symptom Possible cause Measure
Product not operating The mains voltage has been
interrupted/power cut
▶ Wait until the mains voltage has been re-established and the
product automatically switches on (all settings are retained).
Frost protection active (mains
voltage present)
1. Check whether S.815 is displayed in the Live Monitor.
2. Wait until the outside temperature increases (the product
automatically switches on no later than 60 minutes after the
temperature increases.).
– Outside temperature: > −3 ℃
