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.

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.
