2. Elementary operator control 3
GB
This room thermostat clock creates
comfortable room temperatures in the
simplest way possible.
The two temperature levels
= Comfort temperature
= Lower temperature
are set with the according knobs.
Settings between 5°C and 30°C possible.
The manual switch can be used to
switch between three operating modes:
Operating mode = Automatic
The unit operates during the set switching
times and switches between and .
Please note that when switching the
manual switch from „Temperature “ to
„ “, the coloured mark on the manual
switch must be aligned for a short time
with the clock symbol on the unit to im-
mediately activate the automatic mode.
Continuous temperature operating modes
= Comfort temperature
= Lower temperature
The selected temperature remains constant
until a different operating mode has been
selected.
Please remember when setting the
switching times that the heating system
requires a certain amount of time before
it reaches the desired temperature.

3. Installation notes 4
GB
Assembly/installation should only be carried out by
qualified person exercising due care.
Switch off the heating system before assembly.
Check and make sure that the connection wires
are not live.
Assembly note:
– only use PVC-sheathed cables (solid wire)
during installation
– may only be attached to a non-conducting,
level and stable surface
– only suitable for ambient conditions where
normal quantities of dirt occur
– if installed properly in accordance with
VDE 0100, Part 40, the components where
contact remains possible may be regarded
as doubly insulated (Class of protection II)
Operating note:
This unit’s electronic unit has been protected
from external interference. However – depending
on the type of assembly – remember that the
mains voltage may be overlaid with extremely
high interference voltage peaks. Also, when
switching coils, e. g. solenoid valves, contactors,
interference occurs that may affect an electronic
unit in spite of all internal protective measures.
To guarantee the greatest operating safety, the
following details must be observed when
connecting:
– where larger plants are concerned, it will
be necessary to shield coils, e. g. solenoid
valves, contactors, that are switched directly
by the unit with a suitable varistor or
RC element
– if inductive DC voltage consumers are
switched, a free-wheeling diode must be
added
– inductive and capacitive loads especially
exert a lot of stress on the output contacts.
In individual cases check, whether the installation
requires
– an isolation relay or contactor or
– an interference suppression filter, e. g. Type
NEF 2.-1,0 A, Messrs. Murr.

3.3 Heating cycle setting/assembly 8
GB
The heating-cycle setting (CDF value) is
for adapting to the control range.
This is affected by:
– Room size
– Type of heating, e. g. convectors,
storey heating
– Type of assembly
– Temperature control/thermostat
The set value can be altered to achieve
an optimum heating control.
Set the value accordingly with the po-
tentiometer on the rear of the unit.
(Factory setting 4)
Place the famoso on it’s base
and resecure.
Recommended settings Set value
Direct electric heating 1 or 2
Supplementary electric 2 or 3
bathroom radiator
Single-room control system 3 or 4
with electrically operated radiator
valves (hot-water heating)
Small or medium-sized rooms
Single-room control system 4 or 5
with electrically operated radiator
valves (hot-water heating)
Medium-sized or large rooms
Wall-mounted gas-fired boiler 4 or 5
for single-storey heating systems
Free-standing gas-fired boiler 4,5 or 6
or oil-fired boiler for larger
living modules

4. Fitting/replacing the batteries 9
GB
Open the battery compartment lid
Fit the batteries
Battery type LR6/AA (2 batteries)
Close the battery compartment lid

5. Setting the correct time/weekday 10
GB
Type 600 day time switch
Type 650 week time switch
Slide the cover upwards and remove.
Day time switch
e. g. 14.00 h
Turn the ring in the direction of the
arrow until the desired hour is aligned
with the locating arrow.
The precise setting is made with the
minute hand.
Week time switch
e. g. Thursday 14.00 h
Turn the ring in the direction of the
arrow until the desired week day is in
the area of the locating arrow.
The precise setting is made with the
minute hand.
Only turn in the direction of the arrow

6.1 Switching times for changing
temperatures with the day time
switch (famoso 600)
e. g. 06.00 – 22.00 hours = Comfort-
temperature
e. g. 22.00 – 06.00 hours = Lower
temperature
Inside segments = Lower
temperature
Outside segments = Comfort-
temperature
1 segment = 15 minutes
6.2 Switching times for changing
temperatures with the week time
switch (famoso 650)
