BPT22
WIRELESS ROOM THERMOSTAT
with socket receiver
BPT22 is an ideal solution in places where installation of the thermostat-boiler wiring is too expensive or
totally impossible. It is intended for automatic control of heating systems in family houses and dwelling units
with their own boiler (gas, electric). The big, backlit display on the transmitter enables control of the
thermostat even in the dark. Moreover, it offers intuitive navigation in the selected language (CZ/PL/EN/DE).
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. BPT22 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).
• Receiver mains supply of 230 V/ 50 Hz
• Receiver with the CODE SELF-LEARNING
system and E-EPROM memory (saving the
code even at voltage failure)
• Two-wire connection to the boiler
(potential-free contact)
• Indicator LED signalling the states
- mains supply indication
- transmission/ reception of signals
- failure state
- relay switched

RECEIVER CONTROL ELEMENTS
RECEIVER INSTALLATION
CODE LEARNING
- Switch off the main circuit breaker.
- Connect the receiver to the boiler according to the wiring diagram (use the boiler terminals
intended for the room thermostat 2 conductors!).
- Connect the receiver to the mains 230 V / 50 Hz.
- Switch on the main circuit breaker; the green diode lights up on the receiver; the receiver is
ready for operation.
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 BPT22 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 yellow 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 inserting batteries, see page 3),
choose the CONST mode by turning the“ “ button, and move on to TEST by pressing
the “ “ button several times. Turn the “ “ button, the signal will be sent to the receiver.
The wireless transmission sign “ “ appears shortly on the transmitter; and after establishing
connection, the RFM message is displayed permanently.
3) The code receipt in the receiver is indicated by simultaneous flashing of the yellow 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 BPT22.
Indicating LEDs:
GREEN LIT - correct mains connection
YELLOW
YELLOW FLASHING - signal transmission
or reception
RED FLASHING - empty E-EPROM memory
RED LIT - FAILURE (if no signal from the transmitter
is received within approx. 6 hours, it switches to the
“2-min-ON / 8-min-OFF” mode)
YELLOW
YELLOW+RED FLASHING ALTERNATELY - code learning mode
YELLOW
YELLOW+RED FLASHING SIMULTANEOUSLY - code has been
learned

BATTERY REPLACEMENT
As soon as the “ “ sign appears on the display, you must replace
the batteries.
1) Remove the control part from the bottom cover of the device (Fig. 1).
2) Replace the batteries. Heed the correct polarity indicated in the
battery compartment (Fig. 2). After you remove the batteries, the
thermostat keeps all settings in the memory for only about 20 s.
Always use alkaline pencil-type batteries 2 x1,5 V type AA!
After replacing the batteries, perform the TEST (see page 5)!
Recommendation: Check the batteries before every heating season!
Dispose of old batteries in conformity with regulations
on hazardous waste handling!
TRANSMITTER DESCRIPTION
TRANSMITTER INSTALLATION
The transmitter must be installed as far from interference sources (TV, PC, etc.) as possible; it
must not be placed on a metal base. Pay attention to the thermal characteristics of the given place at
installation.
- Lift off the back cover of the transmitter acc. to Fig. 1.
- Remove the protective paper from the batteries; the transmitter will be fully operational (batteries
are included in the BPT22 packaging).
- Snap back the back cover.
- The transmitter is freely portable and can be located, for instance, on the table. We recommend
you to use the delivered table stand (installation acc. to Fig. 3).
- If installed on the wall, no power lines must run around the thermostat!
