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 engaged. 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. Outputs 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 assigned under another lit output, scroll to the output 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 thermostat. 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 removed.
Test of room thermostat
If a defect in a room thermostat is suspected, the
following test may be carried out:
- 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 thermostat 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 circuits via wireless communication with the associated 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 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)
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 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 supplier).
