Royal Clima
Short Cycling / Incorrect Thermostat Sensing
The indoor unit frequently turns on and off (short cycling) without reaching the set temperature.

Possible Causes
Room temperature sensor located too close to the cold air outlet, dirty filters causing uneven airflow, an oversized Royal Clima unit for the room size, or a faulty room temperature sensor.
How to Fix / Troubleshooting
Safety first: Turn off the power before accessing sensors.
- Step 1 – Clean filters: Ensure proper airflow to avoid cold air recirculating directly onto the sensor.
- Step 2 – Check sensor position: Make sure the room sensor is in the air intake area, not hanging in the cold air stream.
- Step 3 – Adjust setpoint: Set a moderate temperature (24–25°C) and avoid frequent manual changes.
When to call a technician: Persistent short cycling may require sensor replacement or control board calibration.
