2. Informazzjoni dwar is-Sigurtà
Istruzzjonijiet Importanti dwar is-Sigurtà:
- Periklu Elettriku: Installation must be performed by a qualified electrician in accordance with local and national electrical codes. Disconnect power at the circuit breaker before installation or servicing.
- Ground Fault Circuit Interrupter (GFCI): This thermostat includes a built-in Class A GFCI, which is required for all underfloor heating systems. Test the GFCI regularly as per local codes and manufacturer recommendations.
- Voltage Kompatibilità: Kun żgur li l-volum tat-termostattage (120V or 240V) matches your heating system's voltage.
- Sensor tal-Art: The included floor sensor must be properly installed to prevent overheating and ensure accurate temperature control.
- Tgħaddasx the thermostat or sensor in water.
- Tħaddimx the thermostat with damaged wiring or if it has been dropped or damaged.

3. Konfigurazzjoni u Installazzjoni
Installation of the OJ Microline UTN4-4999 thermostat requires adherence to electrical safety standards. It is recommended that a qualified electrician performs the installation.
3.1 Lista ta 'Kontroll ta' Qabel l-Installazzjoni
- Verify that the power supply to the heating system is disconnected at the main circuit breaker.
- Ikkonferma l-voltage of your heating system (120V or 240V) matches the thermostat's capabilities.
- Ensure you have all necessary tools: screwdriver, wire strippers, electrical tape, etc.
- Locate a suitable wall box for mounting the thermostat.
3.2 Dijagramma tal-Wiring
Refer to the wiring diagram below for proper connection. All connections must be secure and comply with local electrical codes.

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.

4. Operazzjoni
The OJ Microline UTN4-4999 is a non-programmable thermostat designed for simple and direct temperature control.
4.1 Aġġustament tat-Temperatura
To adjust the desired temperature (setpoint), use the Up u Down 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 Modi ta' Kontroll
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. Manutenzjoni
The OJ Microline UTN4-4999 thermostat is designed for minimal maintenance.
- Tindif: Imsaħ il-wiċċ tat-termostat b'ċarruta ratba u damp drapp. Tużax prodotti tat-tindif li joborxu, solventi, jew sprejs kimiċi, għax dawn jistgħu jagħmlu ħsara lid-displej jew liċ-ċinturin.asing.
- Test GFCI: 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.
- Spezzjoni: 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.
