3.3 Floor Sensor Installation
The 10Kohm floor sensor is included and essential for floor temperature control and protection. Install the sensor cable in a conduit or directly within the floor heating system, ensuring it is positioned centrally between heating elements for accurate readings. Do not cut or splice the sensor cable unless specifically instructed by the heating system manufacturer.

3.4 Montiranje termostata
- After wiring, carefully push the thermostat into the wall box.
- Secure the thermostat to the wall box using the provided screws.
- Pričvrstite prednju ploču.
- Vratite napajanje na prekidač.
4. Operacija
The OJ Microline UTN4-4999 is a non-programmable thermostat designed for simple and direct temperature control.
4.1 Podešavanje temperature
Za podešavanje željene temperature (zadane vrijednosti), koristite Up i Dole arrow buttons located below the display. The display will show the current temperature and the setpoint. The heating system will activate or deactivate to maintain the setpoint.

4.2 načina upravljanja
The thermostat offers three control modes, selectable based on your heating requirements and floor type:
- (A) Ambient temperature with Floor protection: The thermostat controls based on the room's air temperature, but will limit the floor temperature to prevent overheating, especially important for sensitive floor coverings like laminate or engineered wood.
- (B) Floor temperature with Floor protection: The thermostat controls directly based on the floor sensor reading, also with an upper limit for floor protection. This mode is ideal for maintaining a consistent floor surface temperature.
- (C) Ambient temperature without Floor protection: The thermostat controls solely based on the room's air temperature, without an upper limit on floor temperature. Use this mode only if your floor covering can withstand high temperatures.
Consult your heating system installer or the thermostat's advanced settings (if available, refer to the full technical manual for details) to select the appropriate control mode.
5. Održavanje
The OJ Microline UTN4-4999 thermostat is designed for minimal maintenance.
- čišćenje: Obrišite površinu termostata mekom,amp krpu. Ne koristite abrazivna sredstva za čišćenje, rastvarače ili hemijske sprejeve, jer mogu oštetiti ekran iliasing.
- GFCI test: Regularly test the built-in GFCI as per local electrical codes, typically monthly. Press the "TEST" button on the thermostat. The display should indicate a trip, and the heating will turn off. Press the "RESET" button to restore normal operation. If the GFCI does not trip or reset, contact a qualified electrician.
- inspekcija: Periodically inspect the thermostat and wiring for any signs of damage or loose connections. If any issues are found, disconnect power and consult a qualified electrician.
