Honeywell Temperature Controllers for Valves and Actuators Only

In modern HVAC systems and building automation solutions, Honeywell temperature controllers are essential for precise temperature regulation and optimal system performance.

However, an important note must be made: Honeywell temperature controllers are designed specifically for controlling valves and actuators, not for measurement applications.

So why is that? What are the advantages of using Honeywell controllers with valves and actuators? Let’s explore DLK—the expert supplier of BMS and HVAC devices—in the article below.

1. Overview of Honeywell Temperature Controllers

Honeywell temperature controllers are automation devices used to regulate temperature based on input signals from sensors or measuring instruments. These devices are commonly integrated into HVAC (Heating, Ventilation, and Air Conditioning) systems to maintain desired temperatures in rooms, buildings, or industrial zones.

Some popular Honeywell controller series include:

• T775 Series – Versatile controllers for HVAC systems

• Aquastat Controllers – For water temperature control in heating systems

• TR70/TR75 – Designed for controlling linear valves and valve actuator

2. Why Should Honeywell Temperature Controllers Only Be Used for Valves and Actuators?

Although capable of temperature regulation, Honeywell controllers are optimized specifically for valve and actuator control, particularly in:

• Hot/chilled water flow control valves

• Linear or rotary actuators in HVAC systems

Why not for measurement purposes?
Controllers are not sensors. They do not directly measure temperature for data collection. Instead, they receive input from temperature sensors and send output commands to open/close valves or adjust actuators to maintain the desired system temperature.

Reasons not to use them for other purposes:

• Not as accurate as dedicated measuring devices (sensors)

• Do not support data logging, analytics, or measurement signal transmission

• Not designed for heavy-duty or continuous operations like industrial PLCs

3. Practical Applications of Honeywell Temperature Controllers

Valve Control in HVAC Systems
Honeywell controllers automatically adjust linear or 2-way/3-way valves in cooling/heating systems. When the water temperature exceeds a set threshold, the controller signals the valve to open/close to balance the temperature.

Actuator Control
Valve actuators receive signals from Honeywell controllers to rotate or adjust valves to the appropriate position. Widely used in AHUs, FCUs, central heating, chillers, etc.

Central Water Heating System Applications
In boiler systems, Honeywell temperature controllers can automatically maintain the hot water temperature in tanks or pipelines by controlling heat supply valves.

4. Key Advantages of Honeywell Controllers

Precise Control
While not used for direct measurement, Honeywell’s ON/OFF or modulating control mechanisms ensure stable operation and minimize temperature fluctuations.

Seamless Integration with Honeywell Valves and Actuators
Fully compatible with Honeywell’s valve and actuator product lines, ensuring system uniformity and simplified installation.

Smart Configuration Support
Higher-end models offer LCD screens, analog signal support (0–10V, 4–20mA), relays, or Modbus protocols for BMS integration.

Durable and Industrial-Grade
Built to withstand harsh conditions of temperature and humidity commonly found in industrial environments.
