Temperature setting
Set room temperature on the thermostat dial. On
the right-hand side of the thermostat is a function
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 ther-
mostat, 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 as
signed 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
roomthermostat 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 ti-
mes 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 con-
nection for 8 circuits. This allows max. 24 heat cir-
cuits to be governed.
The master/slave is to be fitted immediately
above the distributor pipe on the wall or in a distri-
bution cabinet. Easy access to plugs and termi-
nals 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 electri-
cal items supplier).
