The RTM-02 temperature controller is used to control receivers (e.g., radiators and heaters, fans, underfloor heating, anti-icing mats, etc.) depending on the temperature around an external NTC sensor. The device allows for temperature control using a potentiometer located on the front panel within the range of -10 to +40 degrees Celsius. For proper operation, the EXTA ZAMEL RTM-02 controller requires the connection of an external NTC-03 probe. The probe is not included with the controller and must be purchased separately. The probe's design complies with standards used in building automation. The sensor has a nominal resistance of 10 kohm and characteristics typical of an NTC component. The probe cable is 3 m long and can be extended to 50 m with a cable with a cross-section of 0.2 to 2.50 mm². Probes cannot be connected. A single probe cannot be used to measure temperature transmitted to multiple controllers.
