GENERALITIES
This device is a battery-powered digital weekly chronostat for
controlling room temperature on three levels: Comfort, Economy
or Off/Antifreeze.
Its main characteristic is the lack of electrical connections; indeed
the ON and OFF signals are transmitted to the receiving unit by radio,
making this device easy and cheap to install, especially when there is
no existing electrical system available.
The chronostat can be used in both heating and air conditioning
systems and it features a large backlit display which shows
all functional indications, the program schedule and the room
temperature reading or, alternatively, the current time.
It allows to set up to 7 different time schedules, each one different
for each day of the week, with a minimum intervention time of 1/2
hour during the 24 hours.
STARTING UP
When starting up for the first time open the battery lid and insert
the batteries in the battery compartment O in Fig. 1, observing the
polarities indicated. The batteries must be alkaline 1.5V type AA.
If necessary carry out a reset operation by inserting a pointed object
through the hole provided (N in Fig. 1); DO NOT USE NEEDLES
OR TOOLS THAT COULD IRREPARABLY DAMAGE THE
CHRONOSTAT.
The buttons present beneath the lower flap are 3:
‘OK’: For programming the time and current day of the week (I in
Fig. 1);
‘ ‘: Forward (G in Fig. 1);
‘ ’: Back (L in Fig. 1);
Setting the current time and day
To set the clock of the chronostat carry out the following steps:
1. Open the flap of the battery compartment.
2. Keep the ‘OK’ button pressed for at least 2 seconds; the hour
digits will start flashing.
3. Set the hour using buttons ‘ ‘ and ‘ ‘.
4. Confirm by pressing ‘OK’; the minute digits will start flashing.
5. Set the minutes using buttons ‘ ‘ and ‘ ‘.
6. Confirm by pressing ‘OK’; the box surrounding the current day of
the week will start flashing.
7. Set the current day of the week using buttons ‘ ‘ and ‘ ‘
(the current day is highlighted by a box surrounding the number
corresponding to the day of the week, 1 Monday .. 7 Sunday )
8. Confirm by pressing ‘OK’.
Setting the Heating / Cooling mode
The chronostat leaves the factory set in the heating mode.
The chronostat is factory set to heating mode. To modify the operating
logic, keep the ‘ ‘ button pressed for at least 10 seconds.
A. If the chronostat was previously set on heating, the cooling mode
will be set and the ‘ ‘ (fan) symbol will flash on the display for 8
seconds.
B. If the chronostat was previously set on cooling, the heating mode
will be set and the ‘ ‘ (flame) symbol will flash on the display for
8 seconds.
- ENGLISH -

22
During normal operation, the heating output activation is shown by
the flame icon ‘ ‘ whereas the cooling output activation is shown
by the fan icon ’ ’.
Setting the Comfort and Economy temperatures
The Comfort temperature is set by means of the ‘ ‘ knob (M in
Fig. 1) whereas the Economy temperature is set by means of the ‘ ‘
knob (H in Fig. 1).
Note: In order to have a nighttime reduction, the economy
temperature must normally be set on a lower value than the
comfort temperature.
The chronostat will control the room temperature in the comfort or
economy mode according to the schedule programmed (see paragraph
‘SCHEDULE PROGRAMMING‘).
RADIO SYSTEM SET-UP
Before installing the chronostat in the desired position, it is necessary
to test whether the receiving unit correctly receives its radio signals.
The operation is carried out by activating the ‘Test’ mode in the user
menu or using the shortcut pressing together the buttons ‘OK’ and
‘ ’ (with chronostat turned on).
In ‘Test’ mode the chronostat’s display shows the text ‘TEST’ and
continuously transmits ON and OFF commands to the receiver with a
pause of 2 seconds between one and the next. Everytime a command
is trasmitted the symbol ‘ ’ flashes on the display.
The ‘Test’ mode can be exited in the user menu or switching off the
chonostat by pressing the ‘ ’ button.
In any case the ‘Test’ mode will end automatically after approximately
17 minutes.
The ‘Test’ mode must be used to self-learn the address code of
the chonostat on the receiver, afterwards in the receiving unit the
relevant relay output should continuously toggle between On and
Off state, every 2 seconds. This output state in the receiver is
also displayed by its led. If this happens the chronostat is correctly
communicating with the receiver. When the chonostat is positioned
in the desired position, make sure that it still communicates properly
with the receiver.
If the chonostat is positioned too far away from the receiver,
the relay output will always remain On or Off. In this case, it is
recommended that a better position is found, possibly closer to the
receiver, and make sure that it isn’t in the vicinity of metal screens or
reinforced concrete walls which could weaken the radio transmission.
The signal quality can be monitored in the receiver; see the relative
documentation for further information.

‘tESt’: TEST MODE ACTIVATION
Allows to activate/deactivate the ‘Test’ mode for the selflearning of
the radio address in the receiver:
On ‘Test’ mode active
OFF ‘Test’ mode deactive
See the ‘Radio system set-up’ section for further details.
‘AFr’: ANTIFREEZE SETTING
The Antifreeze function allows you to select a minimum temperature
to be maintained when the chronostat is off, so as to protect both
the room and the equipment when the room temperature falls below
the set value.
The device leaves the factory with the Antifreeze function set on
3°C.
IMPORTANT: the function is active only when the device has
been set in the heating mode.
To set the Antifreeze temperature, carry out the following steps:
1. Select the parameter ‘AFr’ and press the ‘OK’ button.
2. The display will show the previously set Antifreeze temperature.
3. Press buttons ‘ ’ and ‘ ‘ to change the setting (between OFF,
0.5°C..25°C); every change will be automatically memorized.
4. To exit press the ‘ OK ’ button or else wait 10 seconds without
pressing any button.
‘MOrE’: ADVANCED PARAMETERS MENU SETTINGS
The advanced parameters menu allows the installer to configure the
chonostat’s working.
To access the advanced parameters menu select the ‘MOrE’ parameter
and keep pressed for 2 seconds the ‘OK’ button, the display will show
the first advanced parameter. Pressing repeatedly the ‘ P ‘ button the
following advanced parameters will be scrolled:
‘OFS’ Room temperature offset
‘HISt’ Room temperature regulation hysteresis
‘tMIn’ Minimum output ON time
‘Entc’ External NTC sensor configuration
‘LinF’ Floor temperature lower limit
‘LSUP’ Floor temperature higher limit
Press the ‘OK’ button to display the value of the parameter. To
modify the selected parameter use the arrow buttons ‘ ’ and ‘ ’.
Press the ‘OK’ button again to save and go back or press ‘ ’ to
exit without saving the changes.
In any case the chonostat exits automatically after 20 seconds of
no buttons activity.
‘OFS’: ROOM TEMPERATURE OFFSET
With the Offset parameter it is possible to correct the temperature
reading by ±9.9 °C in order to correct any systematic reading errors
due to a positioning of the chronostat in areas unsuitable for room

29
temperature measure. The device is factory set with the Offset to
0.0°C.
‘HYSt’: ROOM TEMPERATURE REGULATION HYSTERESIS
With this parameter it is possible to customize the room temperature
regulation modifing the hysteresis in the 0.1 .. 5.0 °C range. The
device is factory set with the hysteresis to 0.2°C.
‘tMIn’: MINIMUM OUTPUT ON TIME
This parameter allows to reduce the number of ON/OFF cycles of the
output. This function is useful in case the chronostat drives a pellet
stove which cannot be switched On and Off for a too short time.
Once the receiver’s relay is switched On according to a heating
(or cooling) need of the room, it will not be switched Off until the
‘minimum On time’ is expired. The parameter can be set in 10 minutes
steps in the 0..90 minutes range.
The device is factory set with the ‘minimum On time’ to 0, i.e.
function disabled.
‘Entc’: EXTERNAL NTC SENSOR CONFIGURATION
The chronostat features an input for an optional external NTC sensor
as well as an internal sensor. The sensor can be used to read the room
temperature in case the chronostat must be installed in an unsuitable
position for room temperature measure. Alternatively the external
sensor can be configured for floor temperature reading, which can be
useful in an underfloor heating/cooling system. With the external floor
sensor the chronostat will be able to take into account a minimum
and a maximum floor temperature limit during the room temperature
regulation.
The parameter can be set with the following values:
‘no’: No external sensor wired.
‘rOOM’: External sensor wired to read room temperature.
‘FLOH’: External sensor wired to read floor temperature, but it can
not be shown on the display.
‘FLOS’: External sensor wired to read floor temperature, it can be
shown on the display.
‘LinF’: Floor temperature lower limit.
‘LSUP’: Floor temperature upper limit.
In these parameters it is possibile to set a minimum or maximum floor
temperature limit . In case the external sensor is wired and configured
to read the floor temperature, the chronostat will give priority to the
limits within the floor temperature must stay when regulating the
room temperature.
In heating mode it will be possible to set a lower limit under which
the floor temperature must not fall in order not to feel a cold floor,
while it will be possible to set a upper limit beyond which the floor
temperature must not rise in order to guarantee the maximum
wellness.
The chronostat alerts when it is regulating to maintain the floor
temperature within the limits blinking the ‘ ’ symbol on the display.
The floor temperature lower limit can be set in the 10..30 °C range,
while the upper limit can be set in the 35..50 °C range. The limits can
be disabled setting them under their minimum value pressing the ‘ ’
arrow button until the value ‘no’ appears. The device is factory set
with limits disabled.
- ENGLISH -

CONTROL OF A PELLET STOVE
The chronostat can be configured for temperature regulation by
switching On and Off a pellet stove. The receiver’s output will have
to be connected to the On/Off input of the pellet stove. In order to
reduce the number of switching On and Off cycles of the stove,
configure the parameters:
- HYSt: Room temperature regulation hysteresis to 1.0 °C
- tMIn: Minimum output ON time to 30 minutes
TIME SCHEDULE SHARING WITH OTHER WIRELESS
THERMOSTATS
In a system made by one chronostat and some more plain thermostats
one in each room, it is possible to make the thermostats regulate
according the time schedule programmed in the chronostat.
This can be achieved using a multi-channel receiver and associating
the outputs driven by the themostats to the output driven by the
chronostat. In this way a chronostat and the thermostats associated
with it will form a ‘zone’. For example, in a home, it would be possible
to create the ‘living zone’ and the ‘bedroom zone’, with temperature
regulation in each room according to different time schedules
programmed on two different chronostats. See the receiver’s
documentation for instruction how to associate outputs. In the
receiver, associated channels will receive from the chronostat the
time slot information and therefore the information of which setpoint
temperature, comfort or economy, to use for the regulation. Also the
off or antifreeze states are received by the associated thermostats.
If the chronostat is regulating a comfort temperature, the associated
thermostats will regulate according to their setpoint knob temperature,
instead if the chronostat is regulating an economy temperature,
the associated thermostats will regulate according to a reduction
temperature which can be adjusted in the receiver. Likewise if the
chronostat is off with 5°C antifreeze function, also the associated
thermostats will regulate a 5°C antifreeze temperature.
CLEANING PROGRAM
This program is particularly useful during cleaning when windows are
open and it is pointless either to heat or air condition rooms. In such
cases the output will remain Off for a two hours period. To activate
the program press the ‘ ‘ button: on the display the ‘ ‘ icon will light
up and in place of the clock, the time remaining until the resumption
of normal operation will be displayed.
The device will go back to the previous operating mode after two
hours or if you press the ‘ ‘ button again.
VACATION PROGRAM
If you intend to be away for a relatively long period it is advisable
to activate the Vacation Program, which will suspend the active
operating mode for the desired number of hours (from 1 to 95) or
days (from 1 to 99).
At the end of the set number of hours or days, the chronostat will
go back into the operating mode it was in prior to activation of the
Vacation Program. While it is off, the Antifreeze function will still be
active and the ‘ ‘ symbol will be shown on the display, along with
the countdown of the time remaining until the end of the program.
Note: Access to the vacation program will NOT be enabled while the
- ENGLISH -

31
‘ cleaning program ‘ is on.
To activate the vacation program proceed as follows:
1. Press the ‘ ‘ button: the display will show the ‘ ‘ symbol and
the time ‘ h 00 ‘.
2. Press buttons ‘ ’ and ‘ ‘ to set the vacation time; every
change will be automatically memorized.
Up to 95 hours, the programming is indicated in hours and the
display will show ‘ h XX ‘.
Once that value is exceeded, the device will automatically switch
to the mode for programming the vacation time in days and display
will show ‘ d XX ‘. It will be possible to increase or decrease the
hour or day by one unit at a time, with values ranging from 0 .. 95
hours and 4 .. 99 days.
3. To activate the vacation program for the set time, press the ‘ OK ’
button again or else wait 10 seconds without pressing any button;
The display will show the flashing ‘ ’ icon and the time remaining
until the end of the vacation period.
4. To deactivate the vacation function and resume normal operation,
press the button ‘ ’ button or ‘ ‘.
SWITCHING OFF - ANTIFREEZE FUNCTION
To switch the chronostat On or Off press the ‘ ‘ button. When the
chronostat is Off the display will show the text “OFF” and the output
will be always Off.
In case the antifreeze function has been configured and the
chronostat is in heating mode, the display will show also the ‘ ’
symbol and the room temperature will be regulated according to the
antifreeze value set in the relevant parameter (see paragraph ‘USER
MENU SETTINGS‘).
HOW TO INSERT / REPLACE BATTERIES
The battery charge status is constantly displayed by means of the
‘ ‘ symbol.
The battery charge is at a maximum if all three level indicators are
lit inside the symbol.
Instead the batteries are depleted and must be replaced when the
symbol appears completely empty ‘ ‘.
The ‘ ‘ symbol flashes in case the batteries are too depleted to
allow a radio transmission
To replace the batteries proceed as follows:
1. Open the flap of the battery compartment (Fig. 1).
2. Remove the batteries, prying them out with the aid of a tool if
necessary.
3. Insert the new batteries, which must be alkaline 1.5V type AA.
4. Only if the chronostat does not respond correctly carry out a reset
operation by inserting a pointed object through the hole provided
(N in Fig. 1); DO NOT USE NEEDLES OR TOOLS THAT COULD
IRREPARABLY DAMAGE THE CHRONOSTAT.
5. Check that the time is set correctly; adjust the setting if necessary.
AUTOMATIC OPERATION / 24h MANUAL / PERMANENT
MANUAL OVERRIDE FUNCTION
By pressing the ‘ ‘ button, you can override the program schedule
and the chronostat will control the room temperature according to the
temperature set with the ‘ ‘ knob.
- ENGLISH -

32
By pressing the ‘ ‘, button repeatedly you can switch from Automatic
to 24 hour Manual, from 24 hour Manual to Permanent Manual and
from Permanent Manual back to Automatic.
The two ‘Manual’ modes are shown on the display with the symbol
‘ ‘ manual 24h and with the symbol ‘ ‘ permanent manual.
‘Manual 24h’ mode is a temporary state which lasts until midnight of
the current day afterwards the chronostat returns to the ‘Automatic
mode’ i.e. to follow the programmed time schedule. The ‘permanent
manual’ mode remains always active until it is modified again with
the button ’ ’.
BACKLIGHTING
The display backlight turns on whenever and button is pressed. It turns
off automatically 20 seconds after the last pressing of a button.
TIME / TEMPERATURE INDICATION
Pressing the ‘ ‘ button at any time, the user can choose whether
to display the current time or the room temperature measured.
If an external sensor has been connected to the chronostat and
the chronostat has been configured to show the external sensor’s
reading, pressing repeatedly the ‘ ‘ button the display will cycle
the time, room temperature, floor temperature visualization. The floor
temperature is indicated with the the ‘ ’ symbol on the display.
SAMPLING RATE
In order to optimize the battery life, the chronostat reads the room
temperature and transmits the data to the receiver every 3 minutes.
Therefore it is normal that the displayed temperature is not updated
immediately and one need to wait up to 3 minutes to see the output
switching On or Off. Alternatively pressing ‘OK’ button when in the
main screen, the user can force an update.
For the same reason, at the expiry of the time schedule’s half hour,
there will not be an immediate switch of the output, it will be
necessary to wait up to 3 minutes in the worst case to see the new
output state updated.
CONNECTION TO A TELEPHONE INTERFACE
The chronostat offers the option of connecting a telephone interface with
continuous operation (latching relay) to terminals 8 and 9.
Use of a suitable telephone interface does not require any setting
to be made on the chronostat; for directions on using the telephone
interface see the instruction manual provided.
Via a telephone interface it is possible to turn the chronostat Off or
turn it On in the Permanent Manual mode.
Depending on the commands received from the telephone interface the
chronostat will act according to the following operating logic:
1. Telephone interface contact closed:
The chronostat will switch into the ‘Permanent Manual’ mode: the
‘ ‘ and ‘ ‘ symbols will be shown on the display.
2. Telephone interface contact open, after (and only after) a previous
closure, if no buttons have been pressed (Manual/Off):
The chronostat will be switched off and the word ‘OFF‘ will be
displayed along with the ‘ ‘ symbol. If the ‘Antifreeze’ function
is active the ‘ ‘ symbol will be displayed.
IMPORTANT: the commands input by pressing the control
24h
- ENGLISH -

33
buttons will always have priority over the commands received
from the telephone interface.
If you press the ‘ ’ or ‘ ’ button on the chronostat, the device
will change its status and the ‘ ’ icon will flash to indicate that
the interface command has been overridden by a command input with
a control button.
The ‘ ’ icon will stop flashing if the telephone interface sends the
chronostat the same command as the one made with the button or
if the telephone interface is reset. In such a case the status set by
means of the control button will not be changed and the chronostat
will be ready to receive a new command.
IMPORTANT
If an Off command is sent to the chronostat via the telephone
interface (contact open), it is a good idea to check that the
command has been executed by the chronostat by carrying out
the following realignment procedure:
1. Using the functions of the telephone interface, check that the
contact is open, sending an Off command if necessary.
2. Send a command to the telephone interface to close the
contact (the chronostat will turn on).
3. Using the functions of the telephone interface, check that the
contact is closed.
4. Send a command to the telephone interface to open the
contact (the chronostat will turn off).
During this sequence no commands should be input with
the control buttons as they have priority over the interface
