Note.
• If there is no GSM signal no histogram is shown�
• The level of signal 1 is represented by a horizontal histogram that covers the entire length of the
display�
• The level of signal 2 is represented by a similar histogram to the one used for representing
temperature level T1 (at the bottom right of the display)�
• The level of signal 3 is represented by a similar histogram to the one used for representing
temperature level T2�
• The level of signal 4 is represented by a similar histogram to the one used for representing
temperature level T3�
5� The level of the GSM signal is also represented numerically on the display showing the value of
the parameter CSQ in the first two digits, used for the temperature values�
(The numerical values of the CSQ are defined by the European regulations ETSI 07�07 and can take
on values between 0 and 31, or 99 if the value CSQ cannot be determined)�
As regards remote control via SMS text messages, the GSM chronothermostat 01913 can also be
installed in zones where the level of the GSM signal is equal to 1 (minimum level)�
Vice versa, it is not possible to install the GSM chronothermostat 01913 if there is no GSM signal;
in this case, it is necessary to place the appliance in a different zone to the one hypothesized�
Without a GSM signal, it is not possible to use the remote control functions and send SMS
alarm messages, while all the HVAC control functions remain usable as if the device were a normal
chronothermostat�
12.4 PROCEDURE FOR RESTORING THE INITIAL DATA OF THE GSM MODULE
This procedure enables restoring the initial settings of the parameters used for remote control of the
GSM chronothermostat 01913 (see the tables of paragraph 12�1 on page 24)�
To activate the procedure carry out the following:
1� Access the GSM menu by simultaneously, and for a few seconds, pressing buttons
and
�
2� Using button
scroll through the menus to
GSM COnF
and press
�
3� Using button
scroll through the menus to
GSM rES
and press �
4� Using button
show
YES
on the display and press
�
5� During this procedure the
