CS4 CENTRAL CONTROLLER
TM
A central control unit with built-in wireless
transceiver for complete home heating manage-
ment. Capable of controlling up to 16 rooms
in 5 different zones using MSD4 Thermostats
for underfloor heating and MSA4 Panel Heater
Controller for heating panels. Pre-programmed
for easy Plug & Go installation.
The central control unit features a built-in room
sensor and is supplied with a floor sensor
for controlling the floor heating in the room
concerned.
The unit is designed for flush mounting in a wall
socket. A baseplate for external wall mounting
is available.

WARNINg – Important Safety Instructions
Disconnect the power supply before carrying
out any installation or maintenance work on this
unit and associated components. This unit and
associated components should only be installed
by a competent person (i.e. a qualified electri-
cian). Electrical installation must be in accord-
ance with appropriate statutory regulations.
MOUNTINg Of SENSOR
The floor sensor contains a safety extra-low
voltage (SELV) circuit, allowing it to be placed
as close to the floor surface as possible without
having to take account of the risk of shock
should the sensor cable become damaged.
The two wires connecting the sensor to the
mounting box must be additionally insulated,
e.g. shrink flex.
To prevent loose wires in the fixed installation
from coming into contact with the terminal
block for the floor sensor, they must be re-
strained using cable ties.
It is recommended that the cable and sensor be
placed in a non-conductive installation pipe em-
bedded in the floor (fig. 3). The end of the pipe
must be sealed and the pipe placed as high as
possible in the concrete layer. Alternatively, the
sensor can be embedded directly in the floor.
The sensor cable must be led through a sepa-
rate pipe or segregated from power cables.
The floor sensor must be centred between
loops of heating cable.
GREEN COMFORT
Maximum comfort with low energy consumption
The sensor cable may be extended up to 100
m by means of a separate two-core cable. Two
vacant wires in a multi-core cable used, for
example, to supply current to the floor heating
cable must not be used. The switching peaks of
such current supply lines may create interfer-
ence signals that prevent optimum controller
function. If a shielded cable is used, the shield
must not be connected to earth (PE). The two-
core cable must be placed in a separate pipe or
segregated from power cables.
MOUNTINg Of CENTRAL CONTROLLER
WITh bUILT-IN SENSOR
The room sensor is used for comfort tempera-
ture regulation in rooms. The Central Controller
should be mounted on the wall approx. 1.6 m
above the floor in such a way as to allow free air
circulation around it. The thermostat must never
be covered by a curtain or similar. Observe the
minimum distance from large metal surfaces,
electronic equipment, electric motors, etc.
(fig. 4a). To ensure good transmission, the unit
should be placed as high as possible, min. 50
cm above the floor (fig. 4b). Draughts and direct
sunlight or other heat sources must be avoided
(fig. 4).
Installing the central controller
1. Slide the power button down to Off "0".
2. Release the front cover ONLY by inserting a
small screwdriver into the hole on either side
of the thermostat. (fig. 1)
3. Connect the wires in accordance with the
diagram (fig. 2).
4. Mount the thermostat in the wall socket.
Please ensure that the adapter plate is
properly clipped on the thermostat.
5. Fit the frame and carefully press the cover
onto the thermostat. Ensure that both the
power slide button on the cover and the
power switch pin are down.
dO NOT open the controller by releasing the
four fixing clips on the back.
first time settings:
The first time the Central Controller is con-
nected, push the power slide button to On "I".
Language, time and date must be set using the
buttons. Let the central controller guide you
easily through:
- Language
- Time
- Date
- Zone selection
- Thermostat connection

See user manual.
fAULT LOCATION
If the sensor is disconnected or short-circuited,
the heating system is switched off. The sensor
can be checked against the resistance table
(fig. 5).
ERROR COdES
E0: Internal error. The Central Controller must
be replaced.
E1: Built-in sensor short-circuited or discon-
nected.
E2: External sensor short-circuited or discon-
nected.
E5: Internal overheating. Inspect the installation.
E6: Communication error.
