# Thermometer placement

To ensure your ClimateControl system operates at peak efficiency when paired with a wireless thermometer, proper sensor placement and fan settings are essential.

### Sensor Positioning

Strategic placement is critical for the system to accurately reflect the ambient temperature of the room.

- **Height:** Mount the sensor approximately **1.5 meters** above the floor (at eye level).
- **Proximity:** Maintain a distance of **4 meters** from the indoor unit.
  - *Too close:* Risk of **short-cycling**, where the unit shuts off prematurely.
  - *Too far:* Risk of **overshooting**, where the unit fails to reach the target temperature efficiently.
- **Environment:** Keep the sensor away from direct sunlight, windows, and doors. These areas create localized temperature fluctuations that do not accurately represent the rest of the room.

### Fan Speed Settings

Air-to-air heat pumps rely on consistent air circulation to distribute thermal energy effectively.

- **Recommended Range:** Set the fan speed between **3 and 5**.
- **Efficiency:** Higher fan speeds promote better air mixing, which improves system efficiency.
- **Noise Management:** If a higher fan speed causes unwanted noise, you may reduce it; however, **avoid using speed 1**, especially during heating cycles in cold seasons, as it prevents adequate heat distribution.

### Fine-Tuning Your System

There is no "one-size-fits-all" configuration. Every unit, room, and home layout is unique. If you aren't achieving the desired comfort level, experiment by repositioning the sensor.

> **Important:** After moving the sensor, allow the AC unit at least **24 hours** to adjust and stabilize before making further changes.
