5.1 Pamasangan
- The thermostat is designed for wall mounting.
- Ensure the mounting location is free from direct sunlight, drafts, or other heat sources that could affect temperature readings.
5.2 Kabel
Before wiring, ensure power is OFF at the circuit breaker.
- Connect the thermostat to a dedicated 20 Amp sirkuit.
- Identify the Line (power supply) and Load (heating mat) wires.
- Connect the Line wires to the L1(L) and L2(N) terminals on the thermostat's back panel.
- Connect the Load wires from the heating mat to the 'Load' terminals on the thermostat.

- The thermostat is dual-voltage; it can be used with either 120V or 240V heating mats, but not simultaneously. Verify your heating mat's voltage cocog catu daya.
5.3 Floor Sensor Placement
The floor sensor is crucial for accurate floor temperature control.
- Place the sensor next to the long edge of the QuietWarmth heating mat.
- Ensure the sensor is positioned in the heated area and not near any unheated zones or external heat sources.
- Route the sensor wire carefully to avoid damage during installation of flooring materials.
