ELEKTROBOCK wireless controller BT52

BT52 features:
A new wireless thermostat that allows you to take advantage of all the benefits of OpenTherm (OT+) heating systems and achieve greater savings on your heating bills! It allows you to set the boiler type (universal, Thermona electric or gas, Ferroli, Viessmann) and the thermostat has been tested on the new Viadrus NAOS boiler.

Advantages of BT52:
Possibility to position the thermostat (transmitter) as required.
Predictive system (intelligent timer) guarantees the specified temperature at the desired time
Adaptive controller evaluates the temperature gradient of the room and can determine the time necessary to reach the desired temperature
9 weekly programs (optional) for UT (6 temperature changes per day)
1 weekly program (optional) for DHW (3 time periods with different temperatures)
Choice of control type: equithermal control, equithermal control with correction according to internal temperature, PI control
Display of operating hours information for UT/TUV
Display of outdoor temperature information
Display of heating water temperature and modulation power information
Display of other information sent by the boiler to the receiver (water flow in litres, return temperature, etc. depending on the boiler type)
E-EPROM memory retains all settings indefinitely even in the event of a power failure
Possibility of control via GSM module GST1or GST2 (can be purchased)
Automatic changeover to WINTER or SUMMER time
Automatic indication of boiler maintenance
Measured temperature -9°C to 39°C
Non-freezing mode
Holiday mode and summer mode
Transmitter power supply 2x1.5 V alkaline batteries
The receiver stores the last settings and, in case of wireless signal failure, ensures boiler operation


BPT52 and the use of the OpenTherm protocol:
Based on this protocol, two-way communication takes place between the thermostat and the boiler. The receiver of the BPT52 thermostat receives the necessary information (e.g. outside temperature), which it then processes and transmits to the transmitter. From the information received, the thermostat recalculates the desired water temperature of the heating system, and transmits this back to the boiler. The BPT52 can be used for boilers communicating according to the OpenTherm protocol and meeting the given technical specifications.



EQUITHERM CONTROL SETTINGS:
We have prepared a clear graphical display of the equitherm curves. By selecting the number and shift of the curve, you can optimize the boiler operation and achieve the desired values of heating water temperature at different outdoor temperature
