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.
