GSM-R5-DIN
1. Introduction
The GSM-R5-DIN ( GSM rele5 for short) is designed to be mounted on a DIN rail
into a switchboard. GSM rele5 can control two independent electrical circuits in a
building e.g. circuit of an accumulator stove and circuit for garage gate control. The
control is made via SMS messages or by ringing. After installation into an electrical box
insert a SIM card of any GSM operator and the device is ready to operate.
The GSM rele5 has 2 digital outputs (Y5, Y6) with a relay, which can control directly
power circuits up to 230 VAC/5 A. It’s possible to control directly e.g. a thermoregulator
circuit of a gas boiler or a coil of one phase contactor 230V AC. The contact of the
contactor can then control either one phase high power appliance (e.g. electrical
radiator) or a coil of three phase contactor of an accumulation stove.
The GSM rele5 has also 2 digital inputs (X1, X2) and 2 analog inputs (A3, A4).
Digital inputs are determined for potencial free contacts. Analog inputs can be used for
measuring the temperature, current or voltage. GSM rele5 has built in two automatic
regulators which use analog inputs from temperature sensors to maintain preset
temperature. The temperature of sensors can be readout via SMS.
There is an internal built in Li-POL accumulator which allows to send an SMS in case
of a power failure and to restore the output status after a power failure. It’s also possible
to monitor the status of inputs and temperatures via SMS during 230 VAC power failure.
Internal data logger keeps records about events and valued of inputs.

2. Package
Content
 1 pc GSM rele5 (order code
GSM-R5-DIN)
 1 pc GSM antenna ANT05S (order code GSM-ANT05S)
 1 pc temperature sensor GSM-C-T2 (based on KTY81-
210), cable - 1 meter
3. Installation
1. To operate the GSM rele5 a SIM card of any GSM operator is necessary. SIM
card must be functional and active. Also some credit is necessary if SIM card is pre-
paid. We recommend to deactivate the PIN code for installation.
2. The SIM card holder can accommodate nano SIM card only (12,3 x 8,8
mm).
3. Insert this prepared SIM card (cut off
corner first) into a SIM card holder. The
proper insertion is indicated by a slight
mechanical click noise. To remove the SIM
card - press the SIM card in direction into the
GSM rele5 until mechanical click. The SIM
card can be the freely removed.
4. Now it’s possible to connect the device to 230V AC power supply. If the
power supply is correct, green LED PWR goes on and blue LED GSM is flashing
slowly. After about 20 seconds, blue LED diode GSM starts flashing with a period 1
per 3 sec. (registered).
5. For the first tests of GSM rele5 the connection of inputs and outputs is not
important. Please keep in mind that the devices connected to OUTPUTS will be
switched on during tests!
6. To test the GSM rele5 press the push button bellow Y5 for a local control.
The yellow LED diode for Y5 lights ON and relay for output Y5 switch on. Send an
SMS from mobile phone (which will be mainly used to control the GSM rele5 ) in
form 1234 OFF to the telephone number of the SIM card inserted into the
GSM rele5 . This will switch off output Y5 and the yellow status LED for Y5 goes
OFF. Simultaneously, the device automatically sends a confirmation SMS message
on performing the operation. The password 1234 can be changed later in
configuration. The GSM rele5 reacts on the SMS text message from any telephone
as long as the access password matches. The very first one (the sender of the first
valid SMS message) will be remembered as master and will receive messages about
events on GSM rele5 . This user can also control the device by “ringing” on the
device.
7. Try “ringing” on device. You can make pulse on Y6 for approx. 4 seconds by
calling to GSM rele5 (with default factory setting). The device hangs up the call and
makes pulse on the Y6. This pulse can be used for example for opening entrance
gate. To test this function call from the phone (which was used to send the first
test SMS to switch off the Y6). The pulse is indicated by yellow LED below Y6 push
button.
8. Try regulation. By default the regulation of Y5 depends on temperature
sensor connected to analog input A3. So connect a temperature sensor into a
analog input A3. Send SMS in form of 1234 Y5 REG 25 to command the device to
maintain temperature to 25°C. The range of regulation is between 0°C and +55°C.
Regulation can be canceled by SMS with command 1234 Y5 OFF.
9. A default factory setting of the GSM rele5 can be recovered by an SMS in
form 1234 !FACTORY. If you made a backup configuration in SeaConfigurator
, your setting can be then restored from backup configuration of SeaConfigurator
program.
10. Names of input, outputs (and its states) and names of commands is possible
to change in SeaConfigurator program. Visit www.seapraha.cz for download it
for free and install the program to your PC.

5. Hardware
5.1 Connectors
2 digital inputs, 2 analog inputs and 2 digital outputs
can be connected GSM rele5 .
L, N – main power supply 230 V AC
Y5, Y6 – digital outputs
A3, A4 – analog inputs
X1, X2 – digital inputs
Analog inputs can be used for temperature
measurement using KTY81-210, PT100 or PT1000
sensor. Length of wires to the sensor is not limited,
but be aware of resistivity of these wires. For KTY81-
210 16 Ω means 1°C.
ATTENTION: Do not exceed the parameters of
inputs and outputs – Chapter Tech. Specification.
For examples of connection see the chapter
Examples of connection.
5.2 Buttons
GSM rele5 has two buttons on front panel for local control of outputs Y5 and Y6. Every
click on a button change state of corresponding output. Example: If output Y5 was
1. Before inserting the SIM card into the GSM rele
5
device, we
recommend to turn off setting of the “PIN code”!
2. Insert the active SIM card (= at least one call was made) to any mobile
telephone and turn off the requirement of setting the PIN. On most
mobile telephones, this option can be found in menu “Setting the
telephone protection”. or “Setup -> Security -> PIN control”.
ATTENTION:
3. GSM rele5 must be mounted by qualified personnel only!

GSM-R5-DIN_User_Manual_EN_v1-11.docx Strana 2 z 7
switched off, after pressing the button Y5 the output will be switched on and after next
pressing the output will be switched off again.
5.3 LED Diodes
The front panel of GSM rele5 contains indication LED diodes PWR, ERR, GSM a LED
diodes for indication inputs (X1, X2, A3, A4) and outputs (Y5, Y6).:
5.4 Backup battery
GSM rele5 is equipped with backup 3.7 V Li-POL battery which enables to operate the
GSM rele5 for several hours in normal mode in case of a 230 VAC power failure (the
battery life time depends on mode of usage). During the battery supply mode the
GSM rele5 the LED PWR blinks at an interval of 1 for 3 seconds.
In case of failure of the main power supply, the device can send an SMS message.
The settings are made in SeaConfigurator – the power supply is listed on the Digital
inputs tab under the name PWW.
5.5 External antenna connector
GSM rele5 is supplied with an external antenna GSM-ANT05S with 2,5dB gain. It is not
recommended to put this type of antenna on metal surface (the signal quality will
degrade). If a GSM rele5 is used in area with a low GSM signal, it’s possible to use
another type of the antenna with higher gain. See other antennas on www.seapraha.cz.
6. Configuration
Configuration of the GSM rele5 can be made in several ways.
6.1 Default Factory Configuration
When outputs Y5 or Y6 are switched on/off, the GSM rele5 sends an SMS message to
the main user (to the telephone number from which it received the first valid command).
The input signal must be stable for certain time (approx. 1 sec) to avoid sending
unwanted SMS messages in case of interference on the input.
Temperature regulators are set up so that the OUTPUT Y5 is regulated by temperature
sensor on INPUT A3 and OUTPUT Y6 from the temperature sensor on INPUT A4.
6.2 Configuration using PC via USB
The configuration (parameter setting) can be done using program SeaConfigurator.
For connection to PC device has micro USB connector.
E.g. GSM rele5 can be set to inform of the 230V AC power failure or restoration via SMS
or by ringing.
6.3 Change of configuration via SMS
Some parameters of GSM rele5 can be configured via SMS:

Caution
When configurating via SMS is important to understand that´s only change of
parameters and it will not match with configuration saved in PC.
7. Control
7.1 Output control by “ringing”
GSM rele5 is set by the manufacturer to switch ON an OUTPUT Y6 for 4 seconds when
any user from the list of users calls to GSM rele5 phone number. This pulse is useful for
an opening of an entry gate. Test this function by a call to GSM rele5 from your mobile
phone (it’s important to send a valid command SMS to GSM rele5 from your mobile
phone if have inserted a “new” SIM card to GSM rele5 ).
GSM rele5 rejects a call and at the same time generates a pulse on an OUTPUT Y6.
7.2 Remote control of GSM rele5 via SMS
GSM rele5 is controlled via SMS of the GMS network. Text SMS are in form:
<PASSWORD> <COMMAND> [<COMMAND >]
Password (access code)
Password is a main security item for GSM rele5 control. Command SMS are accepted
from any phone number. It means anybody who knows the password and the phone
number can control the GSM rele5 . The password is a string of digits (1 to 20) which
must be on the beginning of any command SMS. Otherwise the SMS will be ignored. A
text before the password is automatically ignored. It is useful when command SMS are
sent from Internet GSM gates. The password can be changed using SEAConfigurator on
the tab General or by a configuration SMS message.
Default password set up by manufacturer:
1234
Command
This part of a message specifies a requested action. See the following table for available
commands. GSM rele5 commands are not a case sensitive, it’s possible to use upper
letters as well as lower letters.
Each command is preceded by Yx, where x is the number of controlled output. If output
is not specified, the OUTPUT (Y5) is used as default. Commands ON and Y5 ON and
Y5ON has the same meaning.
It´s possible to use multiple commands in one message separated by a space.
E.g.
1234 ON … switch on device connected to output Y5
1234 Y5 ON … switch on device connected to output Y5
1234 Y6 OFF … switch off device connected to output Y6
1234 Y6 PULSE 5 … an OUTPUT Y6 will be switched on and then after 5 seconds
will be switched off (Notes: if an output is already switched on, it will be just switched
off after 5 seconds)
1234 Y6 reg 5 … requested temperature for the function temperature regulation
of OUTPUT Y6 will be set to + 5°C
Using multiple commands in one SMS message can look like this:
1234 Y5 OFF Y6 REG 25 … switch off output Y5 and sets temperature regulation
on output Y6 to 25 °C according to temperature sensor on input A3.
Confirmation
If a command message contains a valid password (access code) the GSM rele5 returns
a confirmation message which informs if a command was accepted (see chapter Status
SMS). If you don’t want a confirmation message (e. g. when sending a command SMS
from the Internet GSM gates) add a command “NOBACK”.
E.g.
1234 Y5 ON NOBACK … GSM rele5 will switch on device on output Y5 and
will not send message back.
7.3 Local control of outputs
GSM rele5 has 2 push buttons for local control of outputs Y5 a Y6 (see chapter 5.2).
7.4 Status SMS message
Whenever the command SMS contains valid password the GSM rele5 send back Status
message.
Note: if value of parameter Signal is ??, -- or== It´s an error.
7.5 Control using CML (for Smart phones)
This application can use smartphones with Android or iOS. Application
makes easier control of GSM rele5 and state monitoring. You can
download this application from Google Play or Apple Store for free, type
into search „CML SEA“. After installing the application, make the first
registration, take a photo of the QR code of the device into the “paring code”. The QR
code you find in the GSM rele5 package .

10. Examples of connection
10.1 Heating control through contactors
Centralized control of loads connected to switchboard is typical for electric heating. Electronic ripple control causes disconnection of electrical heating in time of high tariffE.
This wiring controls power for electric heater. An electrician would said, that outputs of GSM rele5 are connected into series with centralized control of loads. Outputs of GSM rele5
controls contactors and they control heater and boiler.
On the picture you can see one phase contactors, but three phase contactors can be used as well. – But those could require bigger current through coil. Make sure, that you don´t
exceed allowed current on outputs of GSM rele5 (see Technical specifications).
This wiring works like that. Temperature sensor A3 is able to regulate (switch on/off) output V3. Switching output V3 on/off by temperature sensor A3 is set in factory configuration.
In SeaConfigurator in settings of output Y5 select freezing temperature (set on 5°C and mark “enabled”).And thermoregulator in room set on comfortable temperature (e.g.
22°C). Heater control wirelessly through commands 1234 Y5 ON (heat up to 22°C) a 1234 Y5 OFF (turn off heater). If temperature drops below 5°C Output Y5 will be switched on
and regulates to nonfreezing temperature. If you have enabled heating to freezing temperature in SeaConfigurator, you can´t switch off heating by command 1234 Y5 OFF. If
you need to switch off the heater is possible to disable output by command 1234 Y5 !DIS and then enable again by command 1234 Y5 !EN.
If you want to heat up on higher temperature (for example on 15°C) than is freezing temperature, you can use command 1234 TEPL 15. If selected temperature in command will
be higher (e.g. 25°C) than temperature set on thermoregulator , heater will be turned on until it reaches temperature set on thermoregulator (for example on 22°C).
Output Y6 is possible to use for same circuit with heater. (By factory settings output Y4 is regulated by sensor A4.) or it can be used for boiler, eventually for gate control via ringing
etc.
Temperature alarm setting is independent on temperature regulation (temperature alarm is setting temperature bounds in SeaConfigurator, it can send SMS message if
temperature drops or exceeds selected temperature).

10.2 Comfortable temperature control
If you need regulate higher temperature than temperature set on thermoregulator. You can use different wiring, where you disable thermoregulator by output Y6.
Command 1234 Y6 OFF will enable thermoregulator A3 to regulate heater. Heater will heat until it reaches selected temperature. Those commands can be sent in one SMS message
simultaneously.
Regulation to 25°C 1234 Y6 OFF Y5 TEPL 25 ( thermoregulator is disabled)
Regulation to 22°C 1234 Y6 ON Y5 OFF ( thermoregulator is set to 22°C)
