OVERVIEW
This device is a radio-controlled display thermostat to control
the room temperature with the option to choose among different
setting modes and related set-point temperatures: Comfort,
Economy, Off/Antifrost.
The thermostat is set by default to operate in Comfort,
Economy and Antifrost modes; it can be adapted to the
different installation requirements by modifying the settings and
the final user intervention can be restricted, aiming to optimize
environment comfort and energy saving. The thermostat can be
used in both heating and cooling systems and it is also suitable
for floor heating systems.
START-UP
When activating for the first time, open the thermostat cover, as
shown in paragraph 'INSTALLATION' in (Cof Fig. 6), and insert
batteries with the correct polarity. Batteries shall be 1.5V
alkaline AA type.
Heating/Cooling Set-up
The thermostat is set by default in heating mode.
Hold down ' ' for 10 seconds to modify the regulation mode.
A. Cooling mode will be set if the thermostat was previously set
on heating and the symbol ' ' will flash on display for 8
seconds.
B. Heating mode will be set if the thermostat was previously set
on cooling and the symbol ' ' will flash on display for 8
seconds.
The lit icon ' ' Flame indicates that heating mode is on during
normal operation; on the contrary, cooling activation is signalled
by the Snow icon ' '.
Regulation mode set-up
There are 3 ways to set the room temperature that can either
be selected by pressing ' '.
Comfort: The thermostat sets the room temperature in
comfort mode; this is normally the preferred
temperature during the day-time.
Economy: The thermostat sets the room temperature
according to the economy mode (this is
usually the preferred temperature during
night time).
OFF / Antifrost: Turn off the thermostat; the display will show
the text 'OFF'. If the thermostat was set to
heating mode and the antifreeze function is
active, the icon ' ' will appear on the
display; in this case the room temperature
will be regulated according to the value set
for the antifreeze temperature, in parameter
P02.
(see paragraph 'INSTALLER CONFIGURATION').
The thermostat is set by factory default to use OFF, Comfort
and Economy modes.
Through the installer parameter P01 it is possible to deactivate
the option to select one or more functions (see the 'INSTALLER
CONFIGURATION' paragraph).
Pressing ' ' cyclically scroll among the different activated
setting modes:
Once a setting mode is set, it remains so until the ' ' key is
pressed again.
See the 'INSTALLER CONFIGURATION' paragraph for further
information on how to configure the setting modes.
Set-point Temperature
Fig. 2
During normal operation the display shows the room
temperature detected and the icon for the selected operating
mode. In order to show the relevant set-point temperature
press any of the keys '' or '': the display will show the set-
point temperature and the icon ' ' will turn on (thus showing
that the value shown refers to the set-point temperature).
The icon ' ' turns on along with icon ' ' thus meaning that the
display is showing the ‘Comfort’ set-point temperature or as an
alternative, together with icon ' ' thus meaning that the display
is showing the ’Economy’ set-point temperature.
Pressing the key '' or '' results in modifying the current set-
point temperature. By pressing the key '' or '' the set-point
temperature digits start flashing to point out that the set-point
can be changed.
Pressing the key ' ' while the display is showing the
‘Comfort’ set-point temperature results in switching to the
‘Economy’ set-point display.
On the other hand when the display shows the 'Economy' set-
point pressing the ' ' key results in showing the 'Comfort'
set-point.
A further pressing of the ' ' key results in showing the room
temperature, as well as after a few seconds of inactivity on the
keys.
EXTERNAL NTC SENSOR
The thermostat features an input ('REMOTE SENSOR', Bin
Fig. 6) to connect an external NTC sensor (optional)
alternatively the internal one.
The external sensor can be used to measure the room
temperature when the thermostat is installed in a position which
does not allow a correct room temperature measurement.
When the installation requires an installation with a remote
sensor, it is necessary to set correctly the parameter P09 and
connect a 10 kOhm @ 25°C NTC sensor. If there is any doubt
about the type of sensor to be connected, please consult the
manufacturer.
The thermostat leaves the factory already set to operate with
the internal sensor.
RADIO SYSTEM CONFIGURATION
Check on the paragraph 'COMPATIBILITY WITH
BIDIRECTIONAL WIRELESS SYSTEM', that the receiver to be
paired with the thermostat is a compatible one.
Check if the receiver correctly receives the wireless thermostat
signals before installing the latter in the desired position. The
operation is performed by activating the 'Test' function by
simultaneously pressing '' and '' buttons.
The thermostat displays the icon 'TEST' and continuously
transmits switch-on and off controls to the receiver, with a 2
second pause between them, in 'Test' mode; every time the
thermostat transmits a radio command and only if it receives an
acknowledgment from the receiver, the symbol ' ' lights up
on the display. The 'Test' mode can be interrupted at any time
by pressing ' '. However, the 'Test' mode automatically
ends after approx.17 minutes.
'Test' mode must also be activated to pair a receiver to the
thermostat, this procedure allows the devices to exchange and
memorize their address which will allow them to recognize each
other. In 'Test' mode, in addition to the text 'TEST', the display
will also show 'nd1' or 'Ed1':
nd1: new device 1 - if no receiver has ever been paired.
Ed1: existing device 1 - if a receiver has already been paired.
To pair a receiver with the thermostat, activate the pairing
procedure on the receiver by pressing the relevant button, after
about 10 seconds, if the operation is successful, the thermostat
will confirm the pairing with the text dL1: device learned 1 after
a few moments the thermostat in 'Test' mode will return to
display Ed1: existing device 1 the receiver will also confirm the
successful pairing, with an alternating red-green-red-green
flashing of the LED.
Once paired, the receiver will begin to receive the Test
commands sent by the thermostat and the relay of its output
must continuously switch on and off every 2 seconds, the
status is also indicated by the relevant LED. If the receiver has
no output relay, the LED will flash green at each reception of
the Test command. Observe the LED on the receiver to confirm
that the thermostat is communicating correctly with the
receiver. Correct communication with the receiver can also be
checked on the thermostat: the ' ' symbol lights up on the
thermostat display for a few moments each time the thermostat
receives an acknowledgment command from the receiver. It is
possible to pair more receivers to the same thermostat up to a
maximum of 6. During the Test mode, by pressing the '' or ''
it is possible to select nd2 (new device 2) to nd6 (new device
6) and perform a pairing procedure for each additional receiver.
During the 'Test' mode the thermostat will send commands and
will receive acknowledgment only from the selected receiver in
order to check the correct communication with each single
paired receiver.
Make sure that the two devices still correctly communicate
when positioning the thermostat in the destination area.
The output relay always remains on or off if the thermostat is
positioned too far from the receiver: if so, we recommend to
find a better position, possibly closer to the receiver, and
ensure it is not near metal screens or reinforced concrete walls
that might weaken radio transmission.
The signal quality can be checked with the receiver (see the
relative documentation for further information).
CANCELLATION OF A RECEIVER
In case you have paired the wrong receiver, or need to replace
a receiver, it is necessary to cancel the pairing between the
thermostat and the receiver.
The cancellation procedure takes place by starting the 'Test'
mode as explained in the previous paragraph, select the
receiver to be deleted Ed1-Ed6 with the '' or '' keys, press
and hold the ' ' key for 10 seconds, after cancellation the
display will show nd1 (nd1-nd6).
To avoid malfunctions of the radio system it is important that
the receiver to be cancelled is powered and turned on as the
receiver must receive the pairing cancellation command from
the thermostat.
INSTALLER CONFIGURATION
The installer configuration allows to define the thermostat
operation to set it to the different kinds of rooms and systems.
Hold '' and ' ' simultaneously pressed for a few seconds
until the ' ' symbol and the word ' Con ' (configuration) appear
on the display, to access the configuration parameter. From this
moment, pressing ' ', will scroll among the different installer
parameters identified with 'P' and by the parameter number,
from P01 to P17.
The end of configuration is indicated with the word 'End'. Press
' ' again to save the configuration and then the thermostat
switches to normal operation.
At any time, by pressing for a few seconds the ' ' key, the
configuration menu is quit without saving any changes made.
While scrolling through the parameters, pressing the '' or ''

Reset installer configuration
To reset installer configuration, in order to bring all the
parameters to factory default values, access the configuration
and, when the display shows 'Con', simultaneously press ''
and '' for a few seconds until the screen goes back to normal
mode.
Description of configuration parameters
The installer configuration parameters are shown in table 1 and
explained below.
Some installer parameters may not be displayed as only
the parameters currently required by the configuration are
shown (the configuration value of a parameter, may
exclude one or more subsequent parameters).
P01: allows to customise the regulation modes that can be
selected with the key ' '. The regulation modes available
are Comfort, Economy and OFF: each of these can be enabled
or disabled by changing P01.
The OFF mode will be replaced by Antifrost mode in case P02
is set with an antifrost temperature.
P02: by this parameter the Antifrost temperature can be set:
this will be maintained when the thermostat is turned off.
The antifrost temperature can be set in the range 0.5 .. 25 °C or
disabled by setting the parameter until the value ‘no’ appears.
By factory default this parameter is set at 6 °C.
P03: room temperature offset.
The detected room temperature can be corrected by ±10.0 °C
with the offset, in order to correct any systematic reading error
due to thermostat positioning in unsuitable areas to detect the
room temperature.
By default the device is set with 0.0 °C offset.
P04: sampling time.
To ensure long battery life, the thermostat waits a period of
time between one transmission and another. The period can be
chosen from 1 to 10 minutes. Therefore it’s normal that the
temperature displayed is not immediately updated; moreover
for the same reason it can be necessary to wait some minutes
(up to the sampling time value) to see the receiver's output
switching. A sampling time of 1 to 3 minutes should be chosen
when the heating/cooling system is fast, while with slower
heating systems based on radiators or floor heating, even a
time of 10 minutes allows excellent accuracy and comfort. In
any case, at any time, pressing the ' ' key forces an update
to the receiver. Choosing a longer sampling time will get a
longer battery life.
P05 and P06: these two parameters set the temperature range
within which the set-point temperature can be chosen when the
thermostat is in heating mode. P05 is the lower limit and can be
freely set from 5.0 .. 35.0 °C, while P06 is the higher limit that
can be set in a range from the lower limit, chosen in P05, up to
35.0°C.
Therefore, the widest temperature range is 5 .. 35 °C and can
be easily reduced based on installation requirements.
P07 and P08: these two parameters configure the temperature
range within which the set-point temperature can be set when
the thermostat is in cooling mode, with the same logic of the
previous two points.
The set-point temperature limits are re-defined upon changing
the cooling/heating settings.
P09: NTC sensor configuration.
The thermostat is set by default prepared to operate with the
internal NTC (P09= Int). Alternatively to the internal sensor a
remote sensor can be wired to the connector 'REMOTE
SENSOR', shown with Bin Fig. 6 and set parameter P10 as
'Ext': this way the internal sensor is disabled while the external
is enabled. Make sure to use the proper remote sensor type,
and respect the maximum wire length allowed.
P10: reserved parameter, do not modify.
P11: reserved parameter, do not modify.
P12: hysteresis, represents the amplitude of the hysteresis
which will be used for the room temperature regulation.
P13: reserved parameter, do not modify.
P14: reserved parameter, do not modify.
P15: reserved parameter, do not modify.
P16: reserved parameter, do not modify.
P17: set-point temperature displayed by default.
The thermostat is set by factory default on “no” parameter, so
the thermostat shows the detected room temperature, but if this
parameter s set on “YES”, the displayed temperature is the set
point one, but the room temperature can be temporarily
displayed after the set-point temperature is modified. Instead, if
the parameter is set on “OnL”, “set-point only”, the thermostat
shows only the set-point temperatures (set-point comfort, set-
point economy) and it is not possible to display the room
temperature.

INSTALLATION
WARNING
- Make sure that the transmitted radio signals are
correctly received by the receiving unit before installing
the thermostat.
- Install the thermostat at about 1.5 m from the floor,
away from heat sources, draught and particularly cold
walls (heat bridges), for the room temperature to be
regulated correctly. These notes must be applied to
place the remote sensor when this is used to acquire
the room temperature.
- A remote sensor must be connected using wires having
at least 1.5 mm² section and no longer than 15 metres.
Do not use the same pipes for sensor signals and
mains voltage.
- The installation and electrical connection of the
thermostat must be performed by qualified personnel
