WIRELESS ROOM THERMOSTAT
with simple operation
and a wall-mounted receiver
The great advantage is the two-way communication, quick setting and change of the required
temperature by simply turning the knob on the transmitter. The transmitter is portable, or it can be
installed on the wiring box in the reference room. The receiver is equipped with the code self-
learning system and the E-EPROM memory, which preserves the saved code even at power
failure. The wireless version enables simple and quick installation; therefore, there is no need for
laborious and time-consuming installation of a line between the thermostat and boiler with
penetration through floors. The coverage of the set can reach up to 35 m.
• Receiver power supply 230 V/ 50 Hz.
• Receiver with the CODE SELF-LEARNING
system and the E-EPROM memory (saving
the code even at power failure).
• Two-wire connection to the boiler.
• Indication LED for signalization of the
states
- power supply indication
- failure state
- relay closed.
receiver - wall-mounted
transmitter
• Simple control element for temperature
setting – knob.
• Indication of the boiler switching and error
states by means of a red LED.
•Night attenuation – button for quick
selection of the night attenuation
(automatic decline by 3 °C for the 8-hour
period).
•Anti-freeze temperature .
• Optional internal frame of a different colour
can be bought (according to the sampler at
www.elbock.cz) for a perfect harmony in
the interior.

Low battery indication
Replace the batteries; see page 3
the red LED is flashing on the transmitter
2 times in 8 s
Signal transmission failure between the
transmitter and receiver
Check the connection of the receiver; see
page 2; on the transmitter, push long (for
approx. 3 s) the button to test the
connection (the relay on the receiver must
switch several times).

RECEIVER INSTALLATION
WIRING DIAGRAM
CODE LEARNING
- Lift off the front cover of the receiver acc. to Fig. 1, 2.
- Fix the receiver to the wall (or directly to the wiring box).
- Switch off the main circuit breaker.
- Connect the receiver to the boiler according to the diagram (on the
boiler, use the terminals for wires of the room thermostat 2).
- Connect the receiver to the mains 230 V / 50 Hz.
- Switch on the main circuit breaker; the green LED lights up on the
receiver; thus the receiver is ready for further setting
Owing to disturbance of the signal reception, install the receiver
(in the interior) as far as possible (no less than 0.5 m) from
big metal objects and outside high-current power lines! We
recommend that the installation be done by a person properly
qualified in electrical engineering!
Use if the receiver memory has been erased – the green diode is flashing!
1) Push the receiver’s “FUNCTION BUTTON” for about 1 s; the green and red LEDs start flashing
alternately; and the receiver is awaiting the code (“learning mode”).
2) On the transmitter (after insetting batteries, see page 3), push the button for approx. 5s (push it until
the red LED on the transmitter lights up); then a signal is send out to the receiver and the TEST starts
up.
3) The code receipt in the receiver is indicated by simultaneous flashing of the green and red LED; thus
the code has been learnt. After the code receipt, the output relay is switched several times to verify
correct function of BT012 (the so-called TEST).

TRANSMITTER DECRIPTION
TRANSMITTER INSTALLATION
TRANSMITTER MODES
- Lift off the front cover of the transmitter according to Fig. 5.
- Fix the back cover to the wall (or directly to the wiring box), see Fig. 6.
- Remove the protective paper from the batteries; the transmitter will be fully functional (batteries are
included in the delivery of the BT012 purchased).
- Snap back the front cover onto the back one, see Fig. 8–9.
- When replacing the batteries, heed their correct polarity (Fig. 7).
- The necessity to replace the batteries is indicated by the red LED; it flashes 3 times in 8 s.
- Always use alkaline batteries 2 × 1.5 V, type AA! (Do not use rechargeable batteries.)
Note: Dispose of old batteries in conformity with regulations on hazardous waste handling!
Set the
required
temperature,
e.g. to 22 °C.
At 10 pm, push
shortly
(for approx. 1 s)
the button.
The thermostat
automatically
reduces the
required
temperature by
3 °C for the period
of 8 hours from
pushing of the
button.
Temperature setting/change:
- By simply turning the knob, set the required temperature by the scale (± 1 °C from 11 °C).
- SWITCHING ON of the boiler is indicated by the red LED; it flashes once per 8 s.
Night attenuation:
It is used to automatically reduce the temperature by 3 °C for the 8-hour period. This cycle is
automatically repeated every day.
- Within the required time, shortly push (for approx. 1 s) the button; the diode flashes 4 times;
thus the mode is active.
- If you again shortly push the button during the night attenuation, the starting hour of the night attenuation
changes and a new 8-hour cycle starts to count down.
- By turning the temperature change knob, you can cancel the NIGHT ATTENUATION!
