2.1.6 0-10 V Input
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:
• CO

sensor; ventilation control according to
carbon dioxide levels;
• Moisture sensor; ventilation control according
to moisture levels.
2.1.7 Geothermal Heat Exchanger (optional)
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.
2.1.8 Frost Protection Device (optional)
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.
2.1.9 Enthalpy Exchanger (optional)
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.
2.1.10 Additional Options
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.
2.2 Available Operating Aids
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.
2.2.1 Display on unit
Settings can be set via the digital display and oper-
ating panel on the santos unit.
