1. 1

   Ensure all indoor units connected to the same outdoor unit are set to the same operating mode (or compatible modes in a multi-zone system).

2. 2

   If using a central controller or home automation system, verify that it's not sending conflicting mode commands.

3. 3

   Power cycle the entire HVAC system by turning off the main power for a few minutes.

4. 4

   After restarting, set all units to a consistent mode and observe.

5. 5

   If the issue persists, review the system's operational settings and consult the Intesis gateway or Samsung system manual.
