AHU Digital Thermostat

The Honeywell T2798I2000 Temperature Controller is an advanced, microcontroller-based solution designed for precise and reliable temperature control in industrial and commercial HVAC systems. Featuring Bluetooth wireless connectivity, it enables convenient monitoring and configuration, enhancing user control and system flexibility.

Equipped with PI (Proportional + Integral) control along with On/Off functionality, this controller ensures stable, accurate, and comfortable temperature regulation. Its backlit LCD display clearly shows both set and measured values, making operation simple and user-friendly.

Designed for versatility, the controller supports both analog (2–10Vdc or 4–20mA) and On/Off outputs, allowing compatibility with a wide range of actuators including damper and valve actuators. It also offers selectable internal and external temperature sensors, enabling operation across a wide temperature range of -20°C to 110°C, making it suitable for demanding applications like steam and chilled water systems.

The unit includes advanced features such as adjustable proportional band, temperature offset, watchdog timer, brownout protection, and manual output override for easy installation and commissioning. Its compact and slim ABS design allows direct wall mounting on standard electrical boxes, ensuring quick and hassle-free installation.

Ideal for applications like hydronic heating, air handling units (AHU), heat exchangers, and condensing towers, the Honeywell T2798I2000 controller enhances system efficiency, reliability, and overall performance.
