INSTRUCTIONS FOR INSTALLATION
The floor heating system consists of:
- Master regulator CFM
- Slave regulator CFS (if > 8 heat circuits)
- Room thermostats CFR
- Zone regulator CFZ (optional)
Master regulator CFM
This regulator governs the individual heat circuits via
wireless communication with the associated room ther-
mostats. Connection of 8 heat circuits is enabled.
If more heat circuits are required, connect one or max.
two slave regulators CFS, each with connection for 8
circuits. This allows max. 24 heat circuits to be gov-
erned.
The master/slave is to be fitted immediately above the
distributor pipe on the wall or in a distribution cabinet.
Easy access to plugs and terminals should be ensured.
See instruction drawing on the opposite page.
If two slave regulators are connected, move the jumper
in “slave 2” to position 2. See instruction drawing.
The connection cable for the slave regulator is 1 m.
Cable lengths of up to 100 m are enabled (available
from your electrical items wholesaler)
If the master regulator is located in a metal cabinet, an
external antenna must be fitted outside the cabinet to
ensure proper reception.
The distance to metal parts must be min. 35 cm.
(Order no. 088H0093)
Alarm
There are 2 options with respect to alarms given by the
master regulator:
-Integral acoustic signal can be selected by moving the
jumper marked “buzzer” from OFF to ON. See installa-
tion drawing.
-External alarm generator can be connected to the output
marked %.
Technical data
Max. ambient temperature 60°C.
Voltage 24 AC at 60 Hz
Enclosure IP40
Room thermostat CFR
Before fitting the room thermostat, register the master
regulator.
See the instructions that come with the room thermostat.
It is important to mark the room thermostat, e.g. with
room or number, to know where in the dwelling it belongs.
Labels are supplied for this purpose.
Zone regulator CFZ
The zone regulator governs a maximum of 6 heat zones.
For each heat zone, individual timing programmes can be
connected. For reading and operating convenience, it is
recommended to place the regulator at eye height.
The connection cable is 5 m. Cable lengths up to 100 m
are permitted (available from your electrical items sup-
plier).

Putting into operation

Fig.1
Fig. 2
Vertical and horizontal LEDs
show the operating mode of the
outputs in combination.
Light: heat is added to the
room.
No light: no heat is added to the
room
Example: When the 4th hori-
zontal LED and the 1st verti-
cal LED are lit, heat is sup-
plied to room 4.
LED row for outputs
Registration of room thermostat with
output(s)
-Connect the room thermostat (fig. 1) and the
CFM master regulator via the black installa-
tion cable. The first vacant output in the reg-
istration field will flash. Other vacant outputs
will be lit. Outputs already registered are not
on (fig. 2).
-If OK is pressed briefly, the room thermo-
stat has been registered with the output and
the LED goes off (fig. 2).
If the room thermostat is to be registered
with more than one output, go to these out-
puts by means of the +/- keys and confirm
by pressing OK briefly.
When the installation cable is removed, the
red LED underneath the battery cover (fig.
1) will flash for at least one minute (Test
mode).
Unregistration of room thermostat
The room thermostat and the master regula-
tor may not be connected.
-Press OK for 5 sec..; the first LED in the row
for registered room thermostat will flash (fig.
2). Other LEDs for registered room thermo-
stats will flash.
-Use the +/- keys to go to the room thermo-
stat to be unregistered (it will flash).
-Confirm unregistration by pressing OK for 5
sec.. The LED goes off.
Test of room thermostat
If a defect in a room thermostat is sus-
pected, the following test may be carried out:
-Set the thermostat to the highest tempera-
ture (EC).
-Move the function switch o the side of the
room thermostat to a new position.
-If the LED underneath the battery cover (fig.
1) flashes quickly for at least one minute,
the room thermostat is in order.
Transmission interval
A room thermostat transmits regularly. When
a signal is received from the master regula-
tor, two quick flashes are sent. Subse-
quently, the normal operating mode is dis-
played.
Operation
During normal operation, the status of the
master regulator outputs is shown.
If the status of the outputs of the slave regu-
lators is to be shown, scroll by means of the
+/- keys. After approx. 10 sec. the system
reverts to the output status of the master
regulator.
Acoustic alarm is disconnected by pressing +/- or pressing OK in the registration field.
