Temperature controller RT-821 – reliable temperature control

The RT-821 temperature controller is a universal device designed to control heating or ventilation devices, ensuring the maintenance of a set temperature in the room. It will work well in both home installations and industrial systems. It is particularly recommended for use in anti-icing systems, where precise temperature control is crucial.

Functionality and application

The RT-821 device controls the operation of heating or ventilation devices, preventing gutters from freezing, driveways and stairs from icing up. Its operation is based on a simple mechanism: until the set temperature is reached, the relay contact is engaged, which turns on the heating device. Once the target value is reached, the contact switches, turning off the heating or turning on the ventilation. A drop in temperature below the set threshold restarts the heating process. Hysteresis adjustment (in the range of 0.5÷3°C) allows you to adjust the regulator's sensitivity to specific needs.

Construction features and operating parameters

The RT-821 is mounted on a standard 35mm rail and occupies 2 module spaces. It is made of high-quality materials, which guarantees its durability and reliability. It has a switching contact with a load capacity of 16A at 230V AC. Thanks to the included probe, the temperature measurement is accurate (±1°C), and the setting is accurate to 1°C. The device operates in a wide range of ambient temperatures (-25 ÷ 50 °C) and has a protection class of IP20. The regulator is powered by 230V AC.

The RT-821 regulator is characterized by a temperature regulation range from -4 to 5°C, a rated switching current of 16A at 230V AC and a switching contact. Mounting is done on a 35mm rail, and the device occupies two module spaces. The degree of protection is IP20, and the hysteresis is adjustable in the range of 0.5 to 3°C with a measurement accuracy of ±1°C.

The RT-821 regulator is a solid and functional solution for every installer and user looking for a reliable temperature control system.
