Notes: – it is necessary to separate the words by one or more blanks – the password field may be omitted if the message sender is a number in the phonebook (see the procedure for phonebook management below) – several commands may be included in a single message for maximum of 160 characters (standard text message).
Page 25
Recording phone numbers in the phonebook The Thermo GSM permits storing within 5 phone numbers in the phonebook, identified with a progressive number from 1 to 5, which can activate/deactivate the instrument with a ring or send text message commands or receive alarms. Storing the first phone numbers in the phonebook To store the first phone number, from the normal operating status: –...
Page 26
Note: remember that if the command sender is not in the telephone book, it is necessary to enter the password before writing the command. For example: PHONEBOOK 2 3921234567 The device replies with a text message confirmation containing the complete phonebook (if a number is not defined, it is indicated with the writing “EMPTY”).
to Thermo GSM with the selected phone number to check it: if the phone number is in the phonebook, the index of the corresponding memory starts flashing (in the example, the phone number is in position 4). Adding a phone number to the phonebook It is possible to add phone numbers to the phonebook just with a phone ring without sending a text message.
Page 28
Setting the operating mode It is possible to set the operating mode of the instrument (ON or OFF). The syntaxes of the commands to send are: TERMO ON TERMO OFF The phone number in the phonebook that sends the command will receive a text message informing of the thermostat status.
Page 29
Some examples: T0 DISABLED excludes the antifreeze temperature (therefore when the instrument is off, there is no regulation) T0 5.5 sets the antifreeze temperature to 5.5°C The phone number in the phonebook that sends the command will receive a text message confirmation.
Page 30
The phone number in the phonebook that sends the command will receive a text message confirmation: NIGHT=ON (-3C INI 22:10 END 6:30) To deactivate the night reduction mode: NIGHT OFF To activate the night reduction mode: NIGHT ON To change the reduction value (delta) without changing time: NIGHT 4 activates the reduction of 4°C compared to the setpoint without changing the previous set time slot Note: if the night reduction mode is set, the symbol “...
N SIM=3331234567 01.07.10 14:55:23 In this case, the writing “(reg)” is related to the measured temperature value of the internal probe and indicates the probe (if there are two probes) on which is performed the regulation. MANAGEMENT OF ALARMS The thermostat can be configured to send text message alarms to phone numbers in the phonebook.

Redirecting unrecognised messages If the thermostat receives a text message that is not recognised as a command, the text message is forwarded to a number in the phonebook. This function can be useful if the telephone operator sends informative messages to the SIM card inserted in the thermostat (for example lack or expiring credit).
Page 36
TERMO NUMBER [number] where [number] is the phone number of the SIM card inserted in the Thermo GSM. The Thermo GSM replies to the sender with the following type of message: TERMO NUMBER 3331234567 Manually If the number of the SIM card in the Thermo GSM is not specified, it is possible to synchronise time and date remotely.
BACKUP BATTERY The instrument has a backup battery that permits operation in case of power supply failure until it is completely discharged. The battery is recharged by Thermo GSM: the battery is completely recharged after about 24 hours of powering by mains supply.
