This chapter describes how you should use the santos.
Congratulations, you are now the own-
er of a santos 570 DC,
a heat recovery unit built by Paul
Wärmerückgewinnung GmbH.
We wish you the highest levels of com-
fort.
The santos unit offers the following functions:
• Balanced ventilation;
• Heat recovery;
• Bypass for free cooling:
• Frost protection;
• Fireplace control;
• Frost protection device (optional);
• 0-10 V input;
• Geothermal Heat Exchanger (optional);
• Enthalpy exchanger (optional).
These terms/properties are described briefly in
more detail in the following sections.
The santos unit has been designed to provide bal-
anced ventilation. Balanced ventilation systems
extract stale air contaminated with smells from the
kitchen, bathroom, WC(s) and, if necessary, a util-
ity room and introduce an equal volume of fresh air
to the living room, bedroom and children's room.
A gap below the doors guarantees good and bal-
anced air circulation in the home.
Ensure these gaps are not blocked by, for ex-
ample, rubber draught excluders or high-pile
carpets. This could prevent the system oper-
ating at an optimum.
Generally speaking, the balanced ventilation sys-
tem comprises the following elements:
• santos (A);
• Duct system for the intake of outside air (B)
and the extraction of indoor air (C);
• Air supply valves in the living rooms and bed-
rooms (D);
• Exhaust air valves in the kitchen, bathroom,
toilet and, if required, the utility room (E);

In addition to a well-balanced ratio between supply
and exhaust air volumes the santos unit also offers
the benefit of heat recovery. Heat recovery removes
the heat from stale exhaust air and transfers it to the
fresh, mostly cooler intake air.
The bypass is used most of all on warmer days in
the summer months to allow in the cool night air.
The bypass functions automatically. All that is re-
quired is to set a comfortable temperature level.
The santos is equipped with frost protection. Frost
protection is an automatic safeguard function that
drastically sinks (or even temporarily interrupts) the
intake of outside air into the santos when there is a
risk of frost. The risk of freezing exists in the winter
months with moderate to heavy frost.
A suitable safety device or integral system safe-
guard is required when jointly operating non room-
sealed fireplaces and ventilation systems if there is
a risk that a dangerous negative pressure can be
created in the room in which the fireplace is located.
The santos is equipped with fireplace control; how-
ever, this must be activated by the installer.
Fireplace control does not replace a safety
device designed to monitor the difference in
pressure; it is a technical precondition for
operating the unit when replaces are being
used at the same time.
Once the replace control is activated the
supply air and exhaust air fans cannot be
deactivated manually.
EN
The santos is equipped with four 0-10 V inputs. It
is possible to connect a variety of different controls
and sensors to these inputs. Several possible ex-
amples are listed below:
• CO2 sensor; ventilation control according to
carbon dioxide levels;
• Moisture sensor; ventilation control according
to moisture levels.
The ventilation system can optionally be equipped
with a geothermal heat exchanger. In addition, the
GHE control valve (Geothermal Heat Exchanger
control valve) makes it possible to route intake air
either directly to the santos or via the ground col-
lector. The geothermal heat exchanger provides
frost-free, temperature controlled intake air with
which the air is fed to the heat recovery unit. In
other words, during frosty weather the outside air
is heated with the aid of the underground geother-
mal heat exchanger before it enters the house via
the santos. By contrast during the summer months
when outdoor temperatures are high the intake air
can be cooled with the aid of the geothermal heat
exchanger before it is introduced into the house.
The GHE control valve operates automatically.
The geothermal heat exchanger is a part of
the ventilation system ductwork and is not
included with the santos.
An optional electric frost protection device can be
fitted in the santos. This has the advantage of en-
suring continued balanced ventilation. As a conse-
quence the supply of cold outside air need not be
restricted or can be restricted later if at all. The frost
protection device turns itself on and off automati-
cally.
The ventilation system can also optionally be
equipped with an enthalpy exchanger. An enthalpy
exchanger helps to regulate the humidity level in the
home. As well as recovering heat the enthalpy ex-
changer also recovers moisture. This process sees
moisture transferred from the exhaust air to the in-
take air and introduced into the ventilated rooms as
fresh supply air. Moreover, enthalpy exchangers are
less susceptible to frost.
In addition to the options described above it is also
possible to equip the santos as follows:
• Connection for forwarding malfunction mes-
sages (remote signalling, cabled);
• Connection for deactivating the fans (cabled);
• Connection for a device to signal a dirty exter-
nal filter.
It is possible to equip the santos with the following
operating aids:
• Display on unit;
• 3-position switch;
• Bathroom switch (optional) to temporarily set
the highest ventilation level;
• CO2 sensor;
• Touchscreen;
• Membrane keypad.
These operating aids are described briefly in more
detail in the following sections.
Settings can be set via the digital display and oper-
ating panel on the santos unit.

The display cannot be used to set santos
ventilation levels. The arrow keys are used
to select additional programmes.
A 3-position switch is used to set the ventilation
levels of the santos. One or more 3-position switch-
es can be installed in a home (for example, in the
kitchen).
When several position switches are installed
in the home the santos operates according
to the highest ventilation level set, unless a
different level is determined in the automatic
software control.
The 3-position switch enables you to set three ven-
tilation levels.
• Level 1 Low.
- Select this level for low ventilation
requirements.
• Level 2 Normal.
- Select this level for normal venti-
lation requirements.
• Level 3 High.
- Select this level when cooking,
showering and when high-level
ventilation is desired.

A bathroom switch can be used to temporarily set
the highest ventilation level available on the san-
tos. To allow excess moisture to be discharged as
quickly as possible after showering this switch is
generally installed in the bathroom. As bathroom
switches are available with very different designs,
no switch is illustrated here.
If desired, the user may enter activation and deac-
tivation time delays for the bathroom switch via the
digital control panel.
Activation delay ensures the highest ventilation level
available on the santos is not activated immediately,
but once the set activation delay time has elapsed.
If the bathroom switch is deactivated dur-
ing the set activation delay time the santos
maintains the current ventilation level and
the highest ventilation level is not activated.
Activation delay is not available to all types
of bathroom switches (such as a pulse
switch). In this case leave the activation de-
lay time setting at 0.
Deactivation delay ensures the santos does not re-
act immediately when the bathroom switch is deac-
tivated, but returns to the normal (or the originally
set) ventilation level once the set deactivation delay
time has elapsed.
The deactivation delay function remains
inactive if the bathroom switch is turned off
during the set activation time.
It is possible to integrate bathroom switch function-
ality into a light switch.
It is possible to regulate the santos with the aid of a
CO2 sensor. A CO2 sensor can be utilised either as a
3-position switch or to convert CO2 concentrations
in the indoor air to a 0-10 V signal to regulate the air
volume required to reduce the concentration CO2 to
permissible levels.
6EN Instructions for the User

As the user you are obliged to service your san-
tos as follows:
• Clean or replace the filters;
• Clean the valves (in the home).
These maintenance procedures are described
briefly in more detail in the following sections.
Failure to (regularly) carry out mainte-
nance procedures on the santos will
impair the long-term performance of the
balanced ventilation system.
Clean or replace the filters as soon as the cor-
responding warning message is displayed on
the digital control panel.
Replace the lters (at least) once every
six months and clean the lters every
2-3 months.
"FiL" and "tEr" are indicated alternately on the
display.
• "
FILTER I
" -> The internal filters must be
cleaned or replaced.
• "
FILTER E
" -> The external filters must be
cleaned or replaced.
One of the filter warning messages stated
above will be indicated on the display of the
membrane keypad.
The internal lters are supplied as
standard with the santos. The (optional)
external lters belong to the ductwork of
the ventilation system and are not part
of the santos.
9System Functions EN
For replacement ...
1. Press OK (display on unit) or " " for at
least four seconds (key on keypad), until
the filter warning message is cleared.
2. Isolate the unit from the mains power sup-
ply.
3. Lift the front panel (A) upwards and re-
move from the santos unit.
4. Pull the handles (B) of the filter cartridges.
5. Pull the used filters (C) out of the santos.
6. Insert the new filters into the santos.
7. Ensure the handles (B) of the filter car-
tridges lock into place.
8. Reconnect the unit to the mains power
supply.
For cleaning ...
Instead of replacing the used filters (C) for new
ones you can clean the filters (when necessary)
using a vacuum cleaner.
Clean the lters (and valves) before us-
ing the santos for the rst time. The ven-
tilation system may have become soiled
with building dust during the building
phase.
The valves must be cleaned (at least) twice a
year.
1 Remove the valve from the wall or ceiling;
2 Clean the valve in a warm soap solution;
3 Rinse the valve thoroughly before drying
carefully;
4 Return the valve to EXACTLY THE SAME
POSITION (and IN THE SAME HOLE);
5 Repeat this procedure for the other valves.
About valve settings ...
The installer will have set the valves to ensure
the ventilation system operates to an opti-
mum. Therefore, it is imperative that you do
not change valve settings.
After cleaning, ALWAYS return all valves
in exactly the same position (and in the
same ventilation holes in the wall or ceil-
ing). Returning them to different posi-
tions could impair the performance of
the ventilation system.
The ventilation air is admitted and discharged
via valves. Gaps under the doors ensure that
the air is able to circulate in the home. To en-
sure that the right volumes of air are available
to the rooms, observe the following:
• block the gaps below the doors;
• alter the setting of the valves;
• swap the valves and their posi-
tions.
A malfunction to the santos is displayed as fol-
lows:
• A malfunction message is displayed on
the display of the unit;
• A malfunction message is displayed on
the display of the membrane keypad;
• A malfunction message is displayed on
the touchscreen;
The various malfunction messages are de-
scribed briefly in more detail in the following
sections.
If a malfunction occurs, a corresponding mal-
function message is displayed on the digital
control panel. An 'A' or 'E' code and a number
are always displayed on the display. Please re-
fer to the overview of malfunction messages
for the meaning of the corresponding code.
10 System FunctionsEN
In the event of a malfunction, please contact
the installer. Note the malfunction code indicat-
ed on the display of the digital control panel.
Please also note your santos model type. This
is indicated on the identification plate on the
top of your santos.
The santos must always remain connected to
the mains power supply unless it has to be shut
down for a compelling reason such as a seri-
ous malfunction, for the purpose of cleaning
or replacing the filters or for some other urgent
reason.
The house will not be mechanically venti-
lated if the unit is isolated from the power
supply. Moisture and mould can occur in
the dwelling as a result. Consequently,
you should avoid turning off the santos
for longer periods of time.
DIN 1946-6 species that apart from rea-
sons of maintenance and repairs ventila-
tion systems must be operated continu-
ally. When the home is unoccupied the
system should be operated at the lowest
ventilation level (level 1 set with 3-posi-
tion switch, level "Absent" or an intermit-
tent holiday programme set via the mem-
brane keypad on the operating unit).
It is possible that condensation will form
on the outside of the unit if the unit is in-
stalled in a room subject to above aver-
age levels of humidity (for example bath-
room or kitchen). This is perfectly normal
and does not impair the functional per-
formance of the system.
Discuss with your supplier what you should do
with your santos at the end of its service life.
If you are unable to return the santos to your
supplier, do not simply dispose of it via the
household waste; contact your local authority
to find out about the possibility of recycling the
components or environmentally safe process-
ing of the materials.

Observe the following points when assessing if the
santos can be installed in a particular room:
• In addition to observing the instructions con-
tained in this manual you must comply with lo-
cal safety and installation regulations specified
by, amongst others, public utility companies
when installing the santos.
• When selecting the place of installation ensure
there is sufficient space around the santos for
air connections, supply and exhaust air ducts
as well as for carrying out maintenance work.
• The following installations must be available in
the room:
- Air duct connections.
- 230 V mains power supply.
- Connection for the condensation drain.
• Install the santos in a frost-protected room.
Ensure the condensation water is discharged
frost-free with a downward gradient and in-
cludes a trap.
We recommend you do not install the unit in
a room with an on average higher level of hu-
midity.
To ensure good and draught-free ventilation
of the dwelling, ensure there are 10 mm gaps
below the indoor doors. If these gaps are
blocked, for example with door seals or high-
pile carpets, the circulation of air inside the
dwelling will stagnate. This would prevent
the system from operating at an optimum.
Proceed with due care and attention when trans-
porting and unpacking the santos.
Remove the unit from the packaging only
immediately prior to mounting the unit.
To protect against the ingress of building
dust and moisture cover open ends (duct
connections) during any interruptions to in-
stallation procedures.
Please contact your supplier immediately if you dis-
cover any damage to or parts missing from the de-
livered product. The scope of supply includes:
• Santos 570 DC;
Check the identification plate to ensure it is the
correct unit type.
• Mounting brackets;
• Operating Manual
the santos on a wall with a mass of at least
200 kg/m2.
With other walls we recommend the use of a mount-
ing frame to install on the floor (optional). This helps
to avoid the transmission of structure-borne noise
as much as possible.
• the supplied mounting bracket to the
wall horizontally.
• the condensation drain (not included
in the scope of supply) to the underside of the
santos. The given dimension of 235 mm is in-
tended as a guideline. This value depends on
the type of trap selected.
• Ensure that at least 1 metre of space is left in
front of the santos to allow future maintenance
work.
Observe the following specifications when fitting air
ducts:
• Install silencers of at least 1 meter in length to
the supply and exhaust air connections of the
unit. For relevant advice, please contact Paul
Wärmerückgewinnung GmbH.
• Fit the air ducts to be connected (minimum
ø180 mm), ensuring they are sealed airtight and
offer as little resistance to the flow of air as pos-
sible.
• To guarantee the basic functionality of the bal-
anced ventilation system when utilising flexible
ducting, use only air ducting material from Paul
Wärmerückgewinnung GmbH.
•
. This
prevents the formation of condensation on the
outside of the ducts.
• If it is not possible to avoid creating a low point
when installing the discharge air ducting from
the discharge air connections on the unit to the
wall opening, then a further condensate drain-
age line must be connected at the low point; the
15System Functions EN
reason being discharged air is saturated with
water vapour when confronted with cold out-
door temperatures that causes droplets to form
on the inside of the ductwork.
• If it is planned to install a silencer at the dis-
charge air connection, then this must be routed
upwards by a bend to protect it against being
soaked by condensation flowing back out of
the discharge air ductwork. When mounting the
unit ensure the condensate can be drained with
a good downward gradient along a longer dis-
tance.
• When routed across a roof the exhaust air duct
must have a double-walled or insulated roof
opening. This prevents the formation of con-
densation between the layers of the roof.
• To prevent unnecessary temperature losses in
both summer and winter we recommend you in-
sulate the supply and exhaust air ductwork with
thermal, vapour-tight insulation.

The warm extract air is cooled by the intake air in
the heat exchanger. As a result, moisture contained
in the inside air condenses in the heat exchanger.
The condensation water that forms in the heat ex-
changer is directed towards the trap.
The connection for the condensation drain has an
outside diameter of 32 mm. This is located on the
underside of the santos.
• the condensation drain with a pipe or
hose to the water seal of the domestic waste-
water system.
• the upper edge of the water seal at
least 40 mm below the condensation drain of
the santos unit.
• that the end of the pipe or hose ends be-
low the water level.
16 System FunctionsEN
Ensure that the water seal connected to the
domestic wastewater system is always lled
with water.
Ensure that the hose end terminates at least
60 mm below the water level. This will pre-
vent the santos from drawing in air.
Do not connect the condensate drain direct-
ly to the sewage drain system (for example
owing freely into funnel with condensation
drain at the sewage system)
The santos can be put into operation after instal-
lation.
It is possible to carry out the commissioning proce-
dures utilising P menus on the digital control panel.
These P menus allow various settings (in particular
for ventilation control) to be selected for the san-
tos. An overview of the available P menus is given
below:
P1 View status (from menu P2)
P2 Set time delay values
P3 Set ventilation levels
P4 View temperatures
P5 Set additional control functions
P6 Set additional control functions
P7 Read and reset malfunctions (and sys-
tem information)
P8 Set 0-10 V inputs
P9 View status (from menu P5)
The P menus P1, P2 and P9 are user accessible
and serve mainly for viewing statuses and setting
time delays. The remaining P menus P3 to P8 are
reserved for the installer.
The bypass valve will not move in the rst
4 minutes following a drop in voltage, if the
setting mode is not activated.
