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 32°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 .
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.
Operation notes:
Pointed metal objects should not be used on
keys that need to be operated with an aid (e. g.
needles) – the rubber keys will be damaged!

3.3 Fitting/replacing the batteries 8
GB
Open the battery compartment lid
Fit the batteries
Battery type LR6/AA (2 batteries)
Close the battery compartment lid
Note:
If the actual temperature is not
displayed after the batteries hav
been changed, press the „Reset“
button, see page 16

3.3 Fitting/replacing the batteries 9
GB
Battery symbol is displayed
Change batteries immediately.
Otherwise safe functioning ist not
guaranteed.
The entered data will not be erased
when the batteries are changed.
Note:
The unit measures the battery voltage
when switching on and off. The battery
display will not change if no switching
occurs.

4. Setting the correct time/weekday 10
GB
Type 800 day time switch
Type 850 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

5.1 Switching times for changing
temperatures with the day time
switch (famoso 800)
e. g. 06.00 – 22.00 Uhours = Comfort-
temperature
e. g. 22.00 – 06.00 hours = Lower
temperature
Inside segments = Lower
temperature
Outside segments = Comfort-
temperature
1 segment = 15 minutes
5.2 Switching times for changing
temperatures with the week time
switch (famoso 850)
e. g. Monday - Friday
06.00 – 22.00 h = Comfort-
temperature
22.00 – 06.00 h = Lower
temperature
Saturday - Sunday
06.00 – 24.00 h = Comfort-
temperature
24.00 – 06.00 h = Lower
temperature
Inside segments = Lower
temperature
Outside segments = Comfort-
temperature
1 segment = 1 hour
5. Setting the switching times

6. Switching the temperatures on/off 12
GB
Protection from frost is guaran-
teed in any event because no
settings below 5°C are possible.
❄
The two temperature values – desired
temperatures are set independently of
each other.
Adjustable by 0,5°C steps between
5°C and 32°C.
The last displayed desired value is
stored.
After approx. 4 seconds, the unit
switches into the current state:
actual temperature
Comfort temperature
e. g. +22°C
(Factory setting 21°C)
Lower temperature
e. g. +15°C
(Factory setting 15°C)

7. Manual switch/operating modes 13
GB
The manual switch selects on of
three operating modes:
Operating mode = Automatic
The unit operates during the set times
and switches between and .
Continuous temperature operating
modes
= Comfort temperature
= Lower temperature
The selected temperature remains until
a different operating mode is selected.

8.1 Heating cycle setting/assembly 14
GB
04
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.
The set value from 1 to 6. If the room-
temperature change is too great (e. g.
caused by ventilation), the cycle time
can be prematurely ended or the unit
can be re-activated.
If the temperature difference in the room
is too great, the system switches ON
and OFF too infrequently.
This means that the CDF value must
be reduced.
If the system switches too frequently,
a higher CDF value must be selected
accordingly.
Factory setting CDF = 4
