Cool Mode: Conversely, Cool mode engages your air conditioning system when the room temperature rises above your setpoint. This mode is ideal for warmer months, ensuring a cool and comfortable living space; The “Cool On” indicator will appear on the display when the air conditioning is in operation.

Off Mode: The Off mode deactivates both the heating and cooling systems. In this mode, the thermostat will only display the room temperature, and no heating or cooling will occur.
