TUO GSM Chronothermostat User Manual
GSM wall-mounting chronothermostat powered by mains (230 V~), suitable for the
control of heating and air-conditioning systems.
The device, through the bistable relay, acts on the control circuit of the burner or the
circulation pump (heating), or on the control circuit of the air conditioner (conditioning),
in order to guarantee the desired temperature.
The integrated GSM module allows the remote control of the device via your
smartphone or tablet. It is sufficient to insert a SIM card enabled for telephone traffic in
the appropriate slot: the remote control occurs by sending to the device certain types
of SMS messages, described in this user manual.
Security is guaranteed by the fact that the command messages are interpreted by the
device only if the sender number is saved in the device address book or if they are
accompanied by the SMS protection password.
Every time the device receives a valid command, after executing it, it sends a
confirmation message to the sender.
It is also available an app for iOS or Android devices that allows you to control the
device without having to manually write the text of the command messages.
The device also displays the relative humidity value thanks to the built-in probe.
The colour of the display backlighting can be chosen by the user among the 48
selectable shades. You can even set the backlighting to be variable according to the
difference between the measured temperature and the set one.
The backlighting can be always switched off if the device is installed for example in
bedrooms.

INSTALLATION AND INITIAL CONFIGURATION
The device can be installed on the wall or to cover the 3-module flush-mounting box
(type 503).
We recommend positioning at a height of 1.5 meters from the floor, in an area that
respects as much as possible the average temperature conditions of the entire
environment. Make sure the area is covered by the GSM signal to guarantee
a stable communication. In this regard, the device allows verifying the intensity of the
signal of each operator (see page 47).
Avoid installation near doors or windows, in niches, behind doors and curtains or
in positions with excess or total lack of ventilation, to avoid that the reading of the
temperature measured by the probe is in some way offset.

TUO GSM Chronothermostat User Manual
Once properly installed and powered, the device can be remotely controlled by sending
simple SMS messages.
For this to be possible, the sender of the command (SMS) must be registered on your
TUO GSM device.
It is also possible to send commands without being registered: in this case, however, it
is necessary to know the SMS commands protection password.
However, it is advisable to register at least one number in the phonebook.
This is because the device allows you to report any alarm situations (power failure or
exceeding a preset temperature) and, if they occur, it does so by sending an SMS to
one or more numbers saved in your phonebook.
On pages from 49 to 58 is described the procedure to memorize one or more numbers
in the phonebook of TUO GSM and the commands to be sent to control it.
GENERAL NOTES
A command SMS is structured as follows:
[password] [command] [parameter 1] … [parameter n]
- the words must be separated by one or more empty spaces
- the password can be omitted if the sender of the command is stored in the
phonebook
- it is possible to link several commands in a single message up to a
maximum of three
- to insert numbers with decimal part (ex. 12.6) the separator must be
the point (and not the comma)
- it is possible to write indifferently in lower case or upper case
If the command is correct, the sender receives a reply sms, whose structure is
similar to the command itself, with the addition of the symbol“=” to indicate the
current status.

Set date and time
In normal conditions, when a SIM card is inserted in the device, the synchronization of
the date and time occurs automatically after a couple of minutes from the connection
to the GSM network. However, this function is not guaranteed by all telephone
operators. In the latter case, the date and time can also be set remotely in two ways.
• Automatically
In this case it is necessary to communicate to the device the number of the inserted
SIM card using the command:
CRONO NUMBER [number]
[number] is the number of the SIM card inserted inside TUO GSM
In this case, the device, upon return of the power supply and if date and time had been
lost (for example due to a prolonged blackout), sends a message to itself from which to
acquire the necessary data.
• Manually
If the automatic mode is not active (that is, the number of the SIM card inserted
with the command described above has not been specified to the device), after
receiving the message of power supply reset, synchronize the time remotely using the
command:
CLOCK

Signaling of possible alarm conditions
The device can signal the following particular conditions (alarm conditions), by sending
a sms to one or more numbers stored in your phonebook:
• if the measured temperature falls below a specified value
• if the measured temperature exceeds a specified value
• if the power supply fails (for example in the event of a blackout)
To activate this feature, you need to:
• specify the minimum temperature below which the alarm is triggered
• specify the maximum temperature above which the alarm is triggered
• define for each type of alarm what are the numbers in the phonebook that should
receive the alert
To define the alarm on exceeding the minimum temperature:
SET MINIMUM ALARM INT [threshold] [hysteresis] [delay]
[threshold] = is the temperature value below which an alarm is considered.
[hysteresis] = is the value used to calculate the condition of re-entry from the alarm.
When the measured temperature drops below the value
threshold + hysteresis the device sends the alarm re-entry alarm message
to the recipient
[delay] = is a value (expressed in minutes). Indicates how many minutes after
the threshold it can be considered an alarm.
To define the alarm on exceeding the maximum temperature:
SET ALARM MAXIMUM INT [threshold] [hysteresis] [delay]
[threshold] = is the temperature value above which an alarm is considered.
[hysteresis] = is the value used to calculate the condition of re-entry from the alarm.
When the measured temperature exceeds the value threshold-hysteresis
the device sends the alarm re-entry message to the recipients.
[delay] = is a value (expressed in minutes). Indicates how many minutes after the
threshold it can be considered an alarm.

English
- 56 -
TUO GSM Chronothermostat User Manual
To define the recipients of the alarms:
SEND ALARM MAXIMUM [index] .... [index]
SEND ALARM MAXIMUM [index] .... [index]
SEND ALARM POWER [index] .... [index]
[index] = is the position in the phonebook of the number to which to send the alarm SMS
For example:
SEND ALARM MAXIMUM 2 4
when a maximum alarm occurs, it sends a message to the numbers saved in the
phonebook in position 2 and 4.
SEND ALARM MINIMUM 1 2 3
when a minimum alarm occurs, it sends a message to the numbers saved in the
phonebook in position 1, 2 and 3.
SEND ALARM POWER 1
when a power failure occurs, it sends a message to the number saved in the
phonebook in position 1.
Note: a new recipient configuration overwrites the previous one. For this it is
necessary all recipients must be entered in a single command.
For example, after sending the following two messages:
SEND ALARM MAXIMUM 2 4
SEND ALARM MAXIMUM 3
the device sends the maximum alarm only to the recipient 3 (thus canceling the
recipients 2 and 4).
To ensure that no message is sent in the event of an alarm, use the commands:
SEND ALARM MINIMUM EMPTY
SEND ALARM MAXIMUM EMPTY
SEND ALARM POWER EMPTY

TUO GSM Chronothermostat User Manual
Re-addressing of unrecognized messages
When the device receives a message that is not recognized as a valid command, it
sends it to one of the numbers in its phonebook.
This function can be useful for example when the telephone operator of SIM card
inserted in the device sends a message to signal the approaching of the expiration or
the exhaustion of the credit.
By default the setting requires these messages to be redirected to the number saved in
position 1 of the phonebook.
To change the recipient of these re-addressed messages, use the command:
FORWARD [index]
[index] ] is the index of the device phonebook (1, 2, 3, 4 or 5)
For example:
FORWARD 3: sends unrecognized messages to the phonebook number saved in
position 3
Per disabilitare la funzione di inoltro utilizzare il comando:
FORWARD NONE

Changing the message password protection
For security reasons, the device accepts commands only if their sender is a number
stored in the phonebook.
However, it is possible to send commands to the device even from users that are not
among those stored in the phonebook.
In this case, however, it is necessary to enter the correct password before the
command (it is 1234 by default). For example:
CRONO HEATING
is a command executed only if sent by a number stored in the phonebook
1234 CRONO HEATING
is a command executed even if sent by a number not stored in the phonebook
It is recommended to change the password to ensure greater protection.
To change the password use the command:
PASSWORD [new password]
[new password] is a 4-digit number
For example:
PASSWORD 2276: changes the protection password to 2276.
Command with telephone call (ring)
The numbers saved in the phonebook can change the operating mode of the device
simply by making a telephone ring.
After a ring the device behaves as follows:
• if it is in automatic mode it activates off operation
• if it is in manual mode, it activates off operation
• if it is in off mode it activates automatic or manual operation, depending on which
operation was active before switching off
The number of the phonebook that made the call will receive an informative text
message on the status of the chronothermostat.
