1 2 2 0 R 8 8 0 CFM/CFS CFR CFZ 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) Wiring diagram 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 60C. 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). CFZ CFR CFM T0.5 A T1.25 A 230 VAC:

-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. Operating disturbances are shown as:
- Acoustic alarm in master regulator (if activated)
- Flashes in the registration field of the master regulator
- Alarm symbol in the zone regulator display (if used) Trouble shooting Registration field shows
(Zone regulator shows) Mode Cause of error Outputs LED for master/slave regulator flashes and LED for output flashes. There has been no connection the room thermostat for more than 90 min.
(Alarm symbol in zone regulator flashes) LED for slave regulator and all room thermostats flashes.
(Alarm symbol in zone regulator flashes) Frostdanger No connection to slave regulator
(No display in zone regulator display) No connection to zone regulator
- Defective battery in room thermostat
- Defective room thermostat
- Too long transmission distance to room thermostat
- Present room temperature is be-
low 4C Frost protection:
Output 15 min. open;
45 min. closed. Present output is open.
- Bus cable defective or discon-
nected.
- Slave regulator defective.
- Two slave regulators are installed as slave 1 and slave 2.
- Bus cable defective or disconnected.
- Zone regulator defective.
(Display shows Connection broken) Master regulator does not react
- Defective fuse
- Defective circuit Acoustic alarm is disconnected by pressing +/- or pressing OK in the registration field. FCC ID: XXXTYPE.CFR This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
