Temperature controller - temperature range 4÷30°C without probe, DIN rail mounting, contact: 1NO/NC 230V AC RT-820B

Temperature controller for heating and ventilation

This RT-820 temperature controller from F&F is a reliable device designed for precise control of heating or ventilation systems. It is ideal for both domestic and industrial installations where a constant ambient temperature is required. DIN rail mounting simplifies integration with existing distribution apparatus.

How does it work? The controller monitors the temperature and switches on the heating device when the temperature drops below the set threshold. Once the desired value is reached, the heating device is switched off, and if necessary, a ventilation device can be started. Hysteresis prevents frequent on/off cycles, extending the life of the devices and ensuring a stable temperature.

Solid construction and easy installation. The housing with a width of 2 modules (35mm) provides compact dimensions, and mounting on a standard DIN rail is quick and intuitive. Screw terminals with a cross-section of 4.0 mm² guarantee safe and durable electrical connections. The IP20 protection class protects against touch and ensures safe use.

The RT-820 controller allows temperature regulation in the range of 4°C to 30°C, making it an ideal solution for most comfort applications. It is designed to control heating or ventilation devices and allows a current load of up to 16 A. 1 × NO/NC contact configuration provides flexibility in connecting different types of loads. Adjustable hysteresis in the range of 0.5°C to 3°C allows you to adjust the controller's sensitivity to specific application needs, and the setting accuracy is 1°C. The device operates in a wide range of ambient temperatures, from -25°C to 50°C. It uses a remote RT sensor to measure the temperature in the optimal location.

The RT-820 controller is a practical solution for installers and end-users looking for a reliable and easy-to-use device for temperature control. Contact separation increases installation safety, and LEDs indicating the operating status facilitate the diagnosis of any problems.
