4.2 Beheermodusse

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. Onderhoud

The OJ Microline UTN4-4999 thermostat is designed for minimal maintenance.

• Skoonmaak: Wipe the thermostat's surface with a soft, damp cloth. Do not use abrasive cleaners, solvents, or chemical sprays, as these can damage the display or casing.
• GFCI toets: 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.
• Inspeksie: 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.
