Temperature controller RT-822 with probe included, temperature control range: 30÷60°C, contacts: 1P, I=16A, 2 modules

Temperature controller RT-822 – precise control for comfort

The RT-822 temperature controller is a reliable device designed to control heating and ventilation systems. Its main task is to maintain a set, constant temperature in the room, which translates to user comfort and optimized energy consumption. Mounted on a 35mm rail, it occupies only 2 modules of space in the distribution board.

Functionality and application

The device operates based on a remote sensor that precisely measures the ambient temperature. Once the set value is reached, the controller automatically turns off the heating device or turns on the ventilation – depending on the configuration. This ensures stable thermal conditions without the need for manual adjustment. Hysteresis adjustable in the range of 0.5÷3°C allows you to adapt the precision of operation to the specific needs of the installation.

The RT-822 controller finds application in:

• Underfloor heating systems

• Radiator installations

• Ventilation systems

• Temperature control in utility and commercial premises

• Applications requiring precise temperature regulation

Technical characteristics and benefits

This model is distinguished by a temperature regulation range of 30°C to 60°C, making it an ideal solution for applications requiring higher temperatures, e.g. in buffer heating systems or domestic hot water heating. The switching contact with a load capacity of 16A at a voltage of 230V allows you to control most standard heating devices available on the market.

Additional advantages:

• Compact dimensions: 2 modules allow for easy installation even in crowded distribution boards.

• High accuracy: Setting and measurement accuracy at the level of ±1°C guarantees precise temperature control.

• LED indication: The green LED informs about the power supply, and the red one about the device's operating status – facilitates diagnostics and monitoring.

• Simple installation: Screw terminals allow connection of wires with a cross-section of up to 2.5mm².

• Durability: A wide range of operating temperatures (-25÷50°C) ensures reliable operation in various environmental conditions.

• Safety: Protection class IP20 protects against accidental touching of conductive elements.

The set includes a KTY 81-210 probe with a heat-shrink sleeve and an OMY 2×0.34mm² cable with a length of 2.5m – ready for immediate use after connecting to the controller.
