BPT322 GST
A sophisticated wireless thermostat which can be remotely controlled by means of SMS messages from your mobile phone. Wireless version
enables easy and quick installation. It is not necessary to install labour-consuming lines between the thermostat and boiler that must come
through floors. The transmitter includes two devices, temperature controller and GSM module, which cooperate, thus increasing the comfort
of the heating system control. Simple control elements are used for setting; intuitive navigation in the selected language (CZ/PL/EN/DE/
RU/SVK). Remote control is executed by means of brief SMSs which enable you, for example, to change the required temperature or turn
off the system. The receiver is equipped with a code self-learning system and the E-EPROM memory which saves the code stored even in
the event of voltage failure. BPT322 GST works with two-way communication at the frequency of 433.92 MHz. The assembly may reach
the range of up to 35 m (in built-up area). This unique wireless thermostat with a big backlit display and intelligent PID-control offers a wide
variety of usage in residential houses, offices as well as recreation areas.

RECEIVER CONTROL ELEMENTS
RECEIVER INSTALLATION
- lift off the front cover, see Figs 1,2
- attach the receiver to the wall (or to an installation box)
- turn off main switch
- connect the receiver acc. to the diagram (use terminals for room thermostat - 2 wires)
- connect the receiver to the 230 V/50 Hz power supply
- switch on the power. The green LED will light up and the receiver is ready for activation
Install the receiver (in internal rooms) as far from big metal objects as possible (at least 0.5 m) and far from
power lines owing to interference of the signal received!
It is recommended that the device is installed by a person with adequate qualification in electrical engineering!
The BPT322 GST assembly is configured and ready to use – to put the receiver and transmitter in operation, just
use the TEST function (see page 5)!
If the receiver memory has, however, been cleared – the red diode is flashing – proceed as follows:
1) Press the receiver’s “FUNCTION BUTTON” for about 1.5 sec; the blue and red LEDs start flashing alternately; and the
receiver is awaiting the code (“learning mode“).
2) Press twice the “ MENU “ button on the receiver (after connecting the power supply and activating, see page 3), choose
the TEST mode by turning the“ “ button, and confirm it by pressing “ “button. The TEST RFM message is displayed,
by turning “ “ button start the test.
The sign for wireless transmitting “ “ appears shortly on the transmitter and once communication is established the RFM
sing will lit permanently.
3) The code receipt in the receiver is indicated by simultaneous flashing of the blue and red LEDs; thus the code has been
learnt. After the code receipt, the output relay is switched several times to verify correct function of BPT322 GST.

MINIMUM CONTROL TEMPERATURE
Set the value by turning the “ “ button and press the “ “ button to confirm.
MAXIMUM CONTROL TEMPERATURE
PI = proportional-integral control
The PI-control principle consists in comparison of the current room temperature with the desired temperature.
The PI-control aims at achieving and maintaining the desired temperature without overshooting (see the graph). For correct function of the
PI-control, set the control parameters according to the type of the heating system with respect to the room thermal inertia;
see CONST 6.
Note: If the PI-control is selected, CONST 5 is skipped automatically.
(CONSTANTS)
(English language set by default)
(5 °C set by default)
(39 °C set by default)
Setting the limit of the maximum temperature which can be set. If using the GSM module, you will be
informed by an SMS that the room temperature has risen above this value. Choose within the range from
15 °C to 39 °C (by 0.5 °C).
Set the value by turning the “ “ button and press the “ “ button to confirm.
(PID control set by default)
Choose the type of control by turning the “ “ button and press the “ “ button to confirm.
HS = Hysteresis
Difference between the desired and current temperature.
If the hysteresis is 1 °C and the desired temperature is 20 °C, the thermostat switches off at 20 °C, and on at 19 °C (see the graph).
For correct hysteresis function, set the parameters according to the heating system type; see CONST 5.
Note: If hysteresis is selected, CONST 6 is skipped automatically.
Selection of the control type:
PID = proportional-integral-derivative control
The PID-control principle consists in continuous comparison of the current room temperature with the desired temperature,
and automatic adaptation of the controller to the given conditions.
This is the most perfect continuous control; you can achieve not only short control time, but also high accuracy without permanent con-
trol deviation. The minimum switch-on time is internally set to 2 minutes, the proportional band is 2 °C, the time interval is automatically
recalculated according to current temperature conditions.
Note: If the PID-control is selected, CONST 5 and CONST 6 are skipped automatically.

TECHNICAL PARAMETERS
VOLTAGE FAILURE:
By short voltage failure on receiver comes to connection establishment with transmitter within one hour. It is necessary to set only time (all other settings
remain saved in memory), if there are not rechargeable batteries in the transmitter.
RED LED LIT ON RECEIVER (FAILURE):
The thermostat is in failure mode (2 minutes ON and 8 minutes OFF).
1) Check the transmitter (power supply control).
2) Test the thermostat for correct connection by using TEST mode see page 5.
If the connection between transmitter and receiver is not established, please contact the service department under www.elbock.cz.
PRACTICAL EXAMPLES OF USING
THE THERMOSTAT DOES NOT RESPOND TO SMS COMMANDS:
1) Check the transmitter (power supply control).
2) Check if the SIM card is activated.
If the connection between transmitter and receiver is not established, please contact the service department under www.elbock.cz
USING AND SETTING OF BPT322 GST:
