4.2 Mod Kawalan
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. Penyelenggaraan
The OJ Microline UTN4-4999 thermostat is designed for minimal maintenance.
