WIRELESS ROOM THERMOSTAT

for boilers with OpenTherm communication

The BT52 wireless thermostat is designed to control gas and electric boilers that use the OpenTherm plus (OT +) commu-

nication protocol. It consists of a receiving part (receiver) and a transmitting part (transmitter), which use two-way wireless 

communications on the frequency of 433.92 MHz. This wireless variant allows for easy and quick installation, thus eliminating 

the laborious and time-consuming installation of the line between the thermostat and the boiler with a passage through the 

floor. The receiver is connected to the boiler via the OT communication line. This line transmits data and also powers the rece-

iver. The receiver immediately transmits the data obtained from the boiler to the transmitter, where the data is processed. The 

required heating water is calculated and this request is sent back to the boiler.

• Possibility to place a thermostat (transmitter) as needed.

• Predictive system (smart timer) guarantees determined

temperature at the required time. The adaptive controller evaluates

temperature gradient of the room and can determine the necessary 

time to reach the required temperature.

• 

9 weekly programs (optional) for UT

 (6 temperature changes

for a day).

• 1 week program (optional) for DHW (3 time periods

with different temperatures).

• Choice of regulation type:

equithermal regulation

equithermal control with internal temperature correction

PI regulation

• Display of operating hours information for UT / TUV.

• Display of outdoor temperature information.

• Display of heating water temperature and modulation power in-

formation.

• Display of additional information sent by the boiler to the receiver

(water flow in liters, return temperature, etc. depending on the type

boilers).

• E-EPROM memory retains all settings indefinitely

even in the event of a power failure.

• Possibility of control via GSM module GST1 or GST2 (optional).

• Automatic changeover to WINTER or SUMMER time.

• Automatic indication of boiler maintenance.

• Measured temperature -9 ° C to 39 ° C.

• Antifreeze mode.

• Holiday mode and summer mode.

• Power supply 2x1.5 V alk. battery

• 

Power supply via OT communication 

line directly from the boiler

 (or external 

adapter AD05 - not included)

• 

Receiver with SELF-LEARNING system

CODES and with E-EPROM memory 

(sto-

re code even in case of power failure).

• 

Visual inspection of conditions

using colored indicator LEDs.

The receiver keeps the last settings

and in the event of a wireless failure

signal, ensures the operation of the boiler.
