Installation and operation

Temperature setting

Set room temperature on the thermostat dial. On

the right-hand side of the thermostat is a func-

tion switch with 3 possible settings:

Sun : The room temperature will be as set on the

thermostat.

Clock : Used only if the zone regulator is en-

gaged. The temperature will be as set on the

room thermostat, but in accordance with the

consumption pattern entered.

The consumption pattern in the zone regulator

can be overridden by moving the switch to sun or

moon.

Moon : The room temperature will be as set on

the thermostat - minus 5°C.

Limitation of the setting range

Behind the button for temperature setting are two

lock-pins. These can be placed in the setting

knob as shown in fig. 4 if the thermostat setting

range is to be narrowed.

Putting into operation

Each room thermostat has a unique ID number

preventing conflicts with other thermostats.

A single room thermostat is capable of regulating

several heating outputs, provided these outputs

are assigned to the thermostat.

Assigning thermostats to output(s)

-The installation cable between room thermostat

and CFM (fig. 2) must be connected in assigning

each thermostat to the respective output(s).

-In the LED array the first available output will

flash. The LED in the CFR will also flash. Out-

puts already assigned will not be lit (fig. 2). By

pressing OK the thermostat will be assigned to

that output. If the room thermostat is to be as-

signed under another lit output, scroll to the out-

put by means of the +/- keys, then press OK.

-When the installation cable is removed, the red

LED behind the front panel (fig. 4) will flash for at

least 4 minutes. See "Test of room thermostat"

Removal of assigned thermostat

-It is not necessary to have the installation

cable in place when removing an assigned ther-

mostat. Once a thermostat has been removed, it

may be reassigned to another output.

-Removal of room thermostat is done by pressing

OK for 5 seconds, then the entire LED array will

be lit. Scroll to the specific room thermostat to

be removed with the +/- button,and press OK for

5 seconds. The thermostat has now been re-

moved.

Test of room thermostat

If a defect in a room thermostat is suspected, the

following test may be carried out:

Wireless floorheating controller and room thermostat, type CF

- Set the thermostat to the highest temperature.

- Move the function switch on the side of the

room thermostat to a new position.

- If the LED behind the front panel (fig. 4)

flashes quickly for 4 minutes, the room thermo-

stat is OK.

Battery change

If the battery is getting low, the LED will flash 6

times every 6 seconds. See fig. 4.

Master regulator CFM

This regulator governs the individual heat cir-

cuits via wireless communication with the asso-

ciated room thermostats. 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 governed.

The master/slave is to be fitted immediately

above the distributor pipe on the wall or in a dis-

tribution cabinet. Easy access to plugs and ter-

minals should be ensured. See instruction draw-

ing 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)

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 installation drawing.

-External alarm generator can be connected to

the output marked

Technical data

Max. ambient temperature 60°C.

Enclosure IP40

Zone regulator CFZ

The zone regulator governs a maximum of 6

heat zones. For each heat zone, individual tim-

ing 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 supplier).
