Honeywell DT92 ECO digital thermostat + BDR91 receiver

The Honeywell DT92E ECO digital thermostat (reference DT92E1000) with BDR91 receiver is an advanced solution designed to provide precise and efficient control of heating and cooling systems. This thermostat is equipped with TPI (Time Proportional & Integral) self-learning technology, which automatically adjusts the on and off cycles to optimize comfort and reduce energy consumption. Thanks to its digital design and advanced features, it is ideal for both residential and light commercial applications.

Main features:

• Self-learning TPI control: The TPI Fuzzy Logic algorithm adjusts the heating system's on and off times based on the thermal needs of the environment. As it learns the system's behavior, it adjusts the operating times to maintain a constant temperature and improve energy efficiency.

• ECO function: The ECO mode of the Honeywell DT92E thermostat allows temporarily reducing the setpoint temperature, facilitating significant energy savings without sacrificing comfort. This mode is perfect for when the home or office is unoccupied for a few hours or in situations where intense heating is not required.

• Frost protection: The frost protection mode ensures that the temperature does not drop below a critical level (5 °C), automatically activating the heating system if necessary to prevent damage to pipes or equipment due to extremely low temperatures.

• Adjustable settings: The thermostat allows adjusting the proportional band and the on/off time, giving the user greater control over the system's operation. These adjustments enhance temperature control accuracy and allow customization according to the type of installed system.

Functionalities:

• Informative display: The Honeywell DT92E features a clear digital display that shows the ambient temperature, setpoint value, radio frequency (RF) communication status, relay status, ECO mode activation, countdown, and frost protection alerts. Additionally, it includes a low battery indicator that alerts the user when the batteries need to be replaced.

• Easy installation and setup: The wireless connection between the thermostat and the BDR91 receiver simplifies installation, as it does not require complex wiring. It can be mounted on a wall or placed on a table, adapting to different environments. Moreover, it includes an installer mode that facilitates initial setup and adjustment of technical parameters.

• Fail-safe operation: In the event of an RF communication or power failure, the thermostat is designed to continue operating safely, ensuring that the heating system remains functional until communication is restored.

Technical specifications:

• Applications: The thermostat is compatible with a wide range of heating systems, including gas boilers, heat pumps, 24V AC systems, electric systems, and dual fuel systems. Its flexibility makes it suitable for both domestic and light commercial systems.

• Power supply: The thermostat operates on batteries, while the BDR91 receiver requires a power supply of 230 V, 50-60 Hz. This wireless design allows for quick and easy installation without the need for additional wiring between the thermostat and the heating system.

• Operating range: The temperature adjustment range is from 5 °C to 35 °C, with a control accuracy of ± 0.5 °C, ensuring optimal environmental control. Additionally, it can operate at temperatures up to 40 °C with a humidity level of up to 90% without condensation.

• Switching capacity: The BDR91 receiver is equipped with an SPDT switch that supports currents from 24 to 230 V AC, with a capacity of 5 A resistive or 3 A inductive, making it suitable for a wide range of heating applications.

Applications and benefits:

• Energy efficiency: Thanks to its ECO function and self-learning TPI control, the Honeywell DT92E allows for more efficient energy use, reducing unnecessary heating system operating time. This translates into lower energy bills and a more conscious use of resources.

• Wireless flexibility: The wireless design of the thermostat allows it to be placed anywhere in the home or office without the need for wiring work. This makes it an ideal solution for both new installations and renovations where the use of cables is to be avoided.

• Enhanced safety: The frost protection ensures that the installation is protected even in extreme cold conditions, which is especially useful in cold climates where temperature drops could damage installations.
