Temperature controller 24V DIN rail mounting, contact: 1NO/NC 230V AC RT-820-24V

Temperature controller for heating and ventilation

This RT-820-24V temperature controller from F&F is a reliable device designed for precise control of heating or ventilation systems. DIN rail mounted, it is an ideal solution for both professionals and home users who want to maintain a comfortable temperature in their environment. The device allows you to set the desired temperature, and then automatically turns on or off the connected devices, ensuring stable thermal conditions.

How does it work? The controller monitors the temperature using the included probe (KTY 81-210). When the temperature drops below the set threshold, the relay contact switches on the heating device. Once the set temperature is reached, the contact switches over, turning off the heating or turning on the ventilation. Hysteresis (adjustable in the range of 0.5°C - 3°C) prevents frequent on/off cycles, which extends the life of the devices and ensures a more stable temperature.

Specification and functionality

The RT-820-24V controller is characterized by a wide temperature regulation range from 4°C to 30°C, making it a universal solution for various applications. It has an NO/NC switching contact with a current load of up to 16A at 230V AC. DIN rail mounting (2 modules – 35mm) simplifies installation and integration with existing electrical systems. Status indication with LED diodes (green – power supply, red – operating status) allows for quick diagnostics and device control.

Additionally, the controller has contact separation, which increases safety. 230V AC power supply and power consumption of only 1.1W make the device energy-efficient and environmentally friendly. Protection class IP20 provides protection against accidental contact.
