Error 161 - Mixed operation mode of indoor unit

What does 161 mean?

The outdoor unit is preparing for one mode (e.g., cooling), but some indoor units are trying to operate in the opposite mode (e.g., heating), causing a conflict.

• Conflicting mode selections across different indoor units in the system
• Incorrect system settings on a central controller

Click steps to track your progress.

1. 1

   Ensure all indoor units are set to a compatible operation mode (e.g., all set to cooling or all set to heating).

2. 2

   Check any central controller or home automation system settings for mode conflicts.

3. 3

   Wait for the system to synchronize modes after making adjustments, or power cycle to reset.
