1 Explanation of symbols and safety information
1.1 Explanation of symbols
Warning symbols
Signal words indicate the seriousness of the hazard in
terms of the consequences of not following the safety
instructions.
•NOTICE indicates possible damage to property or
equipment, but where there is no risk of injury.
•CAUTION indicates possible injury.
•WARNING indicates possible severe injury.
•DANGER indicates possible risk to life.
Important information

1.2 Safety precautions
General
BRead the guide carefully and keep it to hand for future
use.
Installation and commissioning
BInstallation and start-up may only be carried out by a
qualified installer.
BThe appliance must not be used by untrained parsons,
children or persons with a physical disability, unless
they are authorised to do so or are supervised by a
person who is responsible for their safety.
BSupervise children to make sure they do not play with
the appliance.
Service and maintenance
BOnly qualified personnel may carry out repairs.
Incorrect repairs can lead to serious risks to the user,
and a reduction in savings.
BOnly use original spare parts.
BService and maintenance must be carried out annually
by an authorised service representative.
Safety instructions in this document are
framed and identified by a warning triangle
which is printed on a grey background.
Electrical hazards are identified by a
lightning symbol surrounded by a warning
triangle.
Notes contain important information in
cases where there is no risk of personal
injury or material losses and are identified
by the symbol shown on the left. They are
bordered by horizontal lines above and
below the text.

3 Accessories for cooling station
The following accessories are available for control of the
passive cooling system:
•LK three-way change over valve (E11.Q12) Three-way
change over valve is connected to the XB2 card in the
cooling station. The three-way change over valve can
be used to by-pass the buffer tank to protect it against
cooling. Power supply 230 V.
•Room transducer for relative humidity and
temperature (E11.TM) (dew point sensor)
Sensor for registering room temperature and
humidity in a reference room. Sauters room
transducer for relative humidity and temperature is
connected to the XB2 card on the cooling station by a
4x2x0.8 mm2cable. Power supply 24 V via the
transformer in the cooling station.
•Electrical distributor for heating/cooling Sauters
electrical distributor for heating/cooling for
underfloor heating loops is connected to the XB2 card
on the cooling station. Room temperature controller,
room transducer for relative humidity and
temperature and actuators are connected to the
distributor. The heat pump's C/O signal (switch from
heating to cooling) is connected to the distributor.
Distributor power supply 230 V. The heat pump's C/O
signal can only be managed from Sauters cable bound
distributor ASV6F116. The remote control controller
from Sauter cannot transfer the signal onwards.
•Electrical room temperature controller for heating/
cooling 230 V. Sauters room temperature controllers
are connected to the distributor by 7x1.5mm2cable.
•Thermal drive for unit valves Sauters thermal drives
for unit valves are connected to the distributor. Power
supply 230 V.
•Dew point monitor and transducer Sauters dew point
monitor and transducer and room temperature sensor
are used for comprehensive dew point monitoring
and are connected to the floor distributor flow line by
a tension strap. Dew point monitor and transducers
are connected to the distributor by 7x1.5mm2cable.
•Dew point monitoring The electronic dew point
monitor (E31.RM1) AL-Re can be used to monitor the
dew point, as a complement to the two recommended
components from Sauter. Power supply 24 V via the
transformer in the cooling station. The dew point
monitor is connected to the XB-2 card of the cooling
station by a 2-core cable.
•Humidity sensor The Humidity sensors (TM1-TM5)
from AL-Re are sensors that are also used for dew
point monitoring and are connected to the electronic
dew point monitor. Maximum of five humidity sensors
can be connected.

4 Passive cooling
The passive cooling station is designed for operation
connected to liquid/water heat pumps 6-17 kW with
underfloor heating systems or fan convectors. The
cooling station consists of a heat exchanger, a
circulation pump, a mixing valve and a circuit board for
control of cooling operation. In cooling operation the
system works to maintain the room temperature despite
the increasing outdoor temperature for greater comfort.
With passive cooling, the compressor in the heat pump
is not used. Instead, the cooling is controlled by the
collector circuit flow. All heating circuits can be used for
cooling.
4.1 Passive cooling 1
Passive cooling in combination with a fan convector. The
temperature is controlled via a thermostat in the fan
convector. It follows therefore that the fan is deactivated
if the room temperature falls. The temperature can also
be regulated using room temperature sensors. In this
case, the mixing valve to the cooling circuit is closed but
the fan continues to run until the room temperature has
fallen to the specified value. The desired flow
temperature is set by the installer.
The system must be protected from condensation,
either by the flow line temperature being set sufficiently
high that no condensation occurs, or by supplementing
with condensation draining/insulation. It is also possible
to supplement the system with a room transducer for
relative humidity and temperature, which ensures that
the flow line temperature is held at a level so that the
condensation does not build up, and dew point monitor,
which shuts off the cooling function if condensation is
created nonetheless.
4.2 Passive cooling 2
Passive cooling in combination with underfloor heating
system. This solution uses the existing underfloor
heating system to cool the room. The system must be
protected from condensation, either by the installer
setting the flow line temperature sufficiently high that
the no condensation occurs. Alternatively, the room
transducer for relative humidity and temperature is
installed, which gives the controller the opportunity to
establish appropriate flow temperature, which does not
cause condensation. The system can also be
supplemented with a dew point monitor, which
interrupts cooling operation if condensation is created
nonetheless.
