Features of Honeywell T2798I-1000

Wide Temperature Control Range:	Capable of controlling temperatures over a broad spectrum (e.g., -20 to 110 °C when using an external temperature sensor). This wide range makes it suitable for diverse applications, including extreme conditions like steam heating or ice water cooling.
Backlit LCD Display:	Features a clear, easy-to-read backlit Liquid Crystal Display. This allows for simultaneous display of both the setpoint and the measured temperature value, enhancing user convenience and monitoring capabilities, especially in dimly lit environments.
Selectable Internal or External Temperature Sensor:	The controller offers the flexibility to use either its integrated internal temperature sensor or connect an external temperature sensor. This allows for optimized sensing based on the specific application requirements.
Adjustable Control Parameters:	Users can fine-tune various control parameters, including Zero Energy Band, On/Off Differential, Proportional Band, and Temperature Offset. This adjustability allows for customization to achieve optimal performance for specific HVAC systems and comfort needs.

FAQ of Honeywell T2798I-1000

What is the Honeywell T2798I-1000?

The Honeywell T2798I-1000 is a digital temperature controller primarily used in commercial heating, ventilation, and air conditioning (HVAC) systems. It regulates room or duct temperature based on a setpoint, providing precise and comfortable temperature control.

What type of control action does it use?

It utilizes PI (Proportional Plus Integral) control action. This algorithm provides accurate and stable temperature regulation, minimizing fluctuations and eliminating steady-state errors, which leads to better comfort and energy efficiency.

Can it use an external temperature sensor?

Yes, the T2798I-1000 offers the flexibility to use either its integrated internal temperature sensor or connect an external temperature sensor, depending on the specific application and sensing requirements.
