Honeywell DT92 Digital Thermostat + BDR91 Receiver

The Honeywell DT92 digital thermostat + BDR91 receiver (reference DT92A1004) is an advanced and efficient solution for controlling heating and cooling systems. Designed with self-learning fuzzy logic TPI control technology, this device optimises thermal comfort and helps reduce energy consumption by making automatic adjustments based on the specific needs of the system and environment. Its wireless design and extensive functionalities make it ideal for both residential and commercial settings.

Main Features:

• Self-learning TPI control: The TPI (Time Proportional & Integral) self-learning technology automatically adjusts heating on and off times, providing precise temperature regulation and improving system efficiency. This continuous learning process optimises energy use, avoiding unnecessary cycles and ensuring constant comfort at home or in the office.

• Frost protection: The frost protection mode ensures that the ambient temperature does not fall below a critical level, protecting pipes and other sensitive elements of the heating system. This function is particularly useful in areas with cold winters, ensuring the system activates automatically if the temperature drops too low.

• ECO mode: The Honeywell DT92 thermostat incorporates an ECO mode that allows the user to reduce the setpoint temperature in situations where intense heating is not needed, such as when the house is empty or during the night. This contributes to significant energy consumption savings.

Functions and Operability:

• Proportional band adjustment: This model allows for the adjustment of the proportional band, improving temperature control accuracy. This means the thermostat can make more precise adjustments based on heat demand, resulting in more efficient heating system control.

• Precise temperature control: With a temperature adjustment range of 5 °C to 35 °C and an accuracy of ± 0.5 °C, this thermostat ensures the user can precisely set the desired temperature. This guarantees adequate comfort and efficient energy use.

• Informative display: The Honeywell DT92 features a digital display that shows the current ambient temperature, setpoint value, wireless communication status, relay status, and other key functions such as ECO mode, countdown, and battery status. This makes it easy for the user to programme and monitor the system at all times.

• Easy installation and operation: The thermostat is designed for quick and easy installation, thanks to its wireless communication system with the BDR91 receiver, avoiding the need for additional wiring. This allows for greater flexibility in device placement and facilitates integration into different heating systems.

Technical Specifications:

• Applications: Compatible with a wide range of heating systems, including 24 V AC systems, gas boilers, heat pumps, steam/gravity systems, and electric systems. It is also suitable for dual fuel systems and both residential and light commercial applications.

• Frequency and power supply: Operates at a frequency of 60 Hz and requires a power supply of 230 V, 50-60 Hz, with a maximum consumption of 1VA. The device needs a constant power supply to operate correctly.

• Durability and reliability: The Honeywell DT92 has an IP30 protection rating and is designed to operate in an ambient temperature range of 0 °C to 40 °C, with a relative humidity level of up to 90% non-condensing. Additionally, the BDR91 receiver's contact capacity is 24 to 230 V AC with a maximum current of 5 A resistive and 3 A inductive.

• Safety features: This thermostat is equipped with safety features such as fail-safe operation, which ensures that the heating system continues to function correctly even in the event of wireless communication failures.

Applications and Benefits:

The Honeywell DT92 digital thermostat is ideal for homes and offices seeking an efficient and reliable heating control solution. Its self-learning TPI function, combined with frost protection and ECO mode, allows for precise temperature control and maximises energy savings. Additionally, its wireless design facilitates installation and avoids the hassle of wiring.
