Wireless thermostat with OT

Description of product

Properties BT52:

A new wireless thermostat that takes advantage of all the benefits of heating systems with OpenTherm (OT +) communication protocol for greater energy savings for heating! The setting and selection of functions is on the transmitter, the receiver indicates all statuses using colored LEDs. It allows to set the type of boiler (universal, Thermona electric or gas., Ferroli, Viessmann, Dakon, De-Dietrich, ACV), the thermostat was also tested on the new Viadrus NAOS boiler.

Advantages BT52:

• Possibility to place the thermostat (transmitter) as needed
• Power supply via OpenTherm line or external source AD05-Jack (included in the package)
• The anticipated system (intelligent timer) guarantees the specified temperature at the desired time
• The adaptive controller evaluates the room temperature gradient and can determine the time necessary to reach the desired temperature
• 9 weekly programs (optional) for UT (6 temperature changes per day)
• 1 week program (optional) for DHW (3 time periods with different temperature)
• Choice of control type: equithermal control, equithermal regulation with internal temperature correction, PI regulation
• Displays operating hours information for UT / DHW
• Display outdoor temperature information
• Display of heating water temperature and modulation power
• Display additional information that the boiler sends to the receiver (water flow in liters, return temperature, etc., depending on the boiler type)
• E-EPROM stores all settings indefinitely even when the power fails
• Control via GSM module GST1 or GST2 (can be purchased)
• Automatic change to WINTER or SUMMER time
• Automatic boiler maintenance indication
• Measured temperature -9 ° C to 39 ° C
• Freezing mode
• Vacation and summer mode
• Transmitter power supply 2x1,5 V alkal. battery
• The receiver keeps the last setting and, in the event of a wireless signal failure, ensures boiler operation

BT52 and OpenTherm protocol usage:

Based on this protocol, two-way communication between the thermostat and the boiler takes place. The BT52 thermostat receiver receives the necessary information (eg on outdoor temperature), which it then processes and transmits to the transmitter. From the information obtained, the thermostat recalculates the desired water temperature of the heating system and passes it back to the boiler. BT52 can be used for boilers communicating under the OpenTherm protocol and meeting the technical specifications.
