Temperature controller in the range of -4 to +5 °C, I=16A, 1 module RT-811

Anti-freeze temperature controller – protection against the effects of low temperatures

This compact temperature controller, housed in a casing only 18 mm wide (1 module), is designed for automatic control of heating devices in anti-icing systems. Its main task is to prevent freezing of gutters, stairs, driveways and other surfaces exposed to low temperatures. Thanks to precise regulation and reliable operation, it provides effective protection against damage caused by frost.

Wide application and easy installation

The device finds application in both domestic and industrial installations. Mounting on a standard 35 mm rail is simple and quick, making installation easier even for less experienced installers. The set includes an RT probe, which allows accurate measurement of ambient temperature and precise control of the heating device.

Precision and flexibility of operation

The controller offers a temperature regulation range from -4°C to +5°C, allowing it to be adapted to different climatic conditions and specific user needs. Adjustable hysteresis (0.5°C to 5°C) allows precise setting of the temperature difference at which the heating device is switched on or off. The setting accuracy is 1°C, and the measurement is ±1°C, which guarantees stable and efficient operation of the system. A red LED indicates the operating status – it lights up when the heating device is working, and goes out when it is switched off. Power is indicated by a green LED.

• Temperature regulation in the range of -4°C to +5°C ensures optimal protection against freezing in typical winter conditions.
• Adjustable hysteresis from 0.5°C to 5°C allows you to adjust the controller's sensitivity to specific needs.
• Relay output guarantees reliable switching of loads up to 16A.
• Compact dimensions of 1 module (18 mm) allow you to save space in the switchgear cabinet.
• The included RT probe allows accurate measurement of ambient temperature at no extra cost.
• Screw terminals allow easy and safe connection of wires with a cross-section of up to 4.0 mm².
• Wide operating temperature range from -25°C to +50°C ensures the possibility of use in difficult environmental conditions.

Thanks to these features, the RT-811 controller is a reliable solution for anyone who wants to protect their installation from the effects of low temperatures and ensure peace of mind during frosty days.
