1. 1

   Check the actual ambient air temperature around the outdoor unit.

2. 2

   Verify that the system's operating parameters for heating mode are correctly set, if adjustable via the Intesis gateway or Samsung interface.

3. 3

   If the temperature is genuinely too high for heating, consider delaying heating operation until conditions are suitable.

4. 4

   Ensure there's adequate airflow around the outdoor unit.

5. 5

   If the ambient temperature is normal, contact a technician to check temperature sensors.
