2.2 Operating instructions
1.
The SIM Card must always be inserted and removed when there is no power supply. If not, the SIM Card read
interface inside the GSM module could be damaged.
2.
Always disable the PIN code of the SIM card. If not, the TEL50.GSM cannot be enabled. Do this using a normal
mobile phone. SIM card (non included) could be for voice traffic only. However we recommend using SIM cards that are
also enabled for data traffic.
3.
Check that the area of use has adequate GSM coverage for the selected operator. Check that the GSM signal is
present using the special LED on the device (see par. 4.6) or a normal mobile phone. Place the device in an area
where there is good signal reception (eg. near a window or door). If there is no signal or the signal is weak, you can
install an external antenna in a more favourable place using the optional lead.
4.
Do not power the TEL50.GSM without first connecting the stilo antenna supplied: otherwise, the power section
of the radio transmitter in the GSM unit could be seriously damaged.
5.
There is no guarantee of SMS message forwarding times from and to the device (commands, querying or alarm
reception). SMS management is the exclusive responsibility of the mobile telephone network companies.

General information
The TEL50.GSM phone remote control has been designed for remote operation of electrical or electro-hydraulic equipment
such as room thermostats, boilers, burners, heaters, zone valves, circulation pumps, irrigation systems, etc. It is particularly
suitable for holiday home installations where there is no fixed telephone network.
The remote control can only be used through the GSM mobile network. Commands can be sent via the fixed telephone network
(DTMF tones) or GSM mobile network (DTMF tones and SMS messages with preset syntax). The TEL50.GSM also allows
connection of an LG-Ni1000 temperature sensor (optional) and forwarding via SMS, subject to special querying, of the
temperature value measured at that time.
The device can handle both a temperature threshold exceeded alarm (adjustable) and a general alarm to be connected to the
respective input on the terminal box. In both cases, activation of the alarm generates a specific SMS that is sent to a
predefined user list.
The 2 control outputs can be enabled completely

4.4 Connection of external antenna (optional)
In the top part of the TEL50.GSM, there is an RF female SMA connector that is normally connected to the specially supplied
stilo antenna. Ensure that the antenna connector is securely fastened.
In some operating conditions, the stilo antenna does not permit optimum reception of the RF signal and, for this reason, the
TEL50.GSM can also be used with a high gain directive or omnidirectional external antenna (optional). If this is necessary,
remove the stilo antenna connector and connect the external antenna one.

TEL50.GSM
Recommendations for use of fixed or external antenna
You are advised to observe the following recommendations:
•
The antenna must be placed at least 2m from any electronic equipment, at least 15cm from any obstacles and in a
position where there is good reception.
•
If malfunctioning or interference to the local electrical equipment occurs during use of the TEL50.GSM, reposition the
device / antenna.
•
Do not use the stilo antenna if the TEL50.GSM is used in enclosed or particularly shielding environments.
•
Use external antennas with characteristics that operate in the GSM Dual Band frequency band (890-960 MHz and 17101880 MHz) with nominal impedance of 50 ohm.
•
Do not hold the antenna when the device is in use. This affects the quality of the connection and requires an increase in
transmission power in the TEL50.GSM.
•
Do not use the TEL50.GSM if the antenna is damaged. Use of antennas prescribed by SIEMENS SpA. is recommended.
4.5 Insertion of SIM card
The SIM-reader is located in the top of the device and can only be accessed by first removing the plastic cover. When correctly
inserted, the SIM card should be positioned as shown in the figure below.
F
F
IMPORTANT: The SIM Card must always be inserted and removed
when there is no power supply. Only reconnect the power supply when
you have finished.
The TEL50.GSM only works with latest generation 3 volt SIM cards. If
you possess an old SIM card, contact your provider who will replace it
with a latest generation one. We recommend using SIM Cards that are
enabled for data traffic.

Basic configuration
With the factory configuration, the TEL50.GSM can already handle the following voice (DTMF tones) and SMS commands.
In order to operate safely and correctly, the device must be correctly connected to the GSM network (see par. 4.6). Carefully
check that this is the case during installation and before leaving the device’s final location.
ABC
6.1 Commands via DTMF tones
Ensure that the calling telephone is enabled to send DTMF tones (multifrequency). Almost all phones
currently on sale (both for fixed network and mobiles) have this option. Make sure that the keypad has
been set correctly. To do this, carefully read the instructions or contact the telephone manufacturer.
The DTMF commands sent to the TEL50.GSM will consist of an ID number for the device receiving the
command (input or output), a command number (ON, OFF or status request) plus a control signal
(confirm or cancel).

When the “#” tone is received, if the command is effected, the sequence of corresponding beeps (ON or OFF) is generated. If
the command is not recognized or is not applicable (for example, if an ON command is sent to an input “31#”), the ERROR tone
is generated. If the “? ” tone is received, the OFF tone is generated as confirmation of the command.
Call the telephone number for the TEL50.GSM and wait for the device to answer (a beep after the first ring).
Dial the command you require from those available (see table).

Extended configuration
Using the basic configuration already present, the user can customize device parametrization by changing some of the system
parameters via SMS. Carefully note any changes made and keep them with these instructions in order to ensure that the
device is correctly controlled even after a long period of time or by other qualified users.
7.1 Creation of a qualified user list
All the telephone numbers of users (both fixed and mobile), up to a maximum of 20, that have access to the different features of
the device are entered in this section. The numbers entered must have a minimum length of 6 numbers to be considered valid.
If the security parameter is enabled (SECURITY=1) the calls coming from numbers not included in the list will not be accepted.
If there are no configured users or the security parameter is disabled (SECURITY=0), the caller’s number will not be checked.
The telephone number and type of user (see below: configuration valid only for commands sent by SMS) must be entered for
each user. All the users in the list will receive notification of temperature alarms (if a remote temperature sensor is present) and
alarms generated by closure of input IN1.
Users can be entered with three different profiles:
Administrator (extension .1)
This type of user has full control of the device and can therefore insert and remove functional parameters, control and check
states of inputs and outputs and receive notification of alarms and temperature readings.
User (extension .2)
This type of user has partial control of the device and can therefore only control and check states of inputs and outputs, receive
notification of alarms and receive temperature readings. He/she cannot change or query functional parameters.
Notify (extension .3)
This type of user has no control of the device and can therefore only receive notification of alarms.

numbers. When this parameter is enabled (SECURITY=1), only the users in the USER list can interact with the device
according to their profile (administrator, user, notify). A voice call or an SMS message from a number that is not on the USER
list will not receive a reply. The SMS number must be exactly the same as the configured SMS or it will not be recognized.
When the list is empty, in case of activation SECURITY=1, the number used to send this SMS will automatically be inserted as
administrator even in case it has been inserted as user or notify.

This alarm may come from any device whose status needs to be monitored (eg. home alarm system, boiler burner block, etc.).
A potential-free contact must be used. When the contact is closed, an SMS is sent to all the users on the USER list. The text of
the message will contain “ALARM IN1” or ALARM followed by a new identification string for the IN1 input if it has been
changed.

Temperature alarm
This alarm can only be generated if the temperature sensor LG-Ni1000 is correctly connected to the respective input. The
alarm and reset values must be set according to a hysteresis cycle. The values themselves will define the alarm activation
logic. If the ALARM value is greater than the RESET value, the alarm will be triggered if the current value is higher than the
alarm value. Consequently, the alarm will stop if the current value is lower than the reset value. If the ALARM value is lower
than the RESET value, operating will be reversed. The factory settings are ALARM=5°C and RESET=6°C (frost protection).
The user can modify the alarm and reset thresholds as shown in the examples below.
When an alarm is triggered, an SMS is sent to all the users on the USER list. The text of the message will contain ALARM
TEMP or ALARM followed by a new identification string for the ANALOG/TEMP analogue input if it has been changed.

7.4 Digital I/O status
In this section, the idle and/or operating condition of the digital input IN1 and relay outputs OUT1 and OUT2 can be redefined.
The factory setting has the following conditions:
- The alarm input IN1 is active high, ie. the alarm is sent with the input IN1 closed
- The control outputs OUT1 and OUT2 are normally open
For input IN1, the alarm status (active low or high) for sending notification to all the users is defined whereas for the outputs,
the idle state is defined (normally open or closed).
These settings can be modified as shown in the table below
