Zone Control

The Zone Control widget allows you to monitor and manage individual zones within the HVAC system through the mobile application. Based on configuration, you can control zone status (Open, Close, or Climate), airflow, and temperature setpoints, and view real‑time temperature and humidity values when sensors are available.

The behavior and availability of zone controls depend on the HVAC system capabilities and configuration that is defined in the Configurator. This allows efficient and flexible control of airflow and temperature distribution across zones.

Log in to the app, the Home screen appears.
Tap the room in which you want to control the Zone Control.
Tap the widget label. The Zone Control screen appears.

NOTE: Zone ON/OFF reflects the HVAC plant power status and is read‑only.

The Zone Control is designed for ducted air‑conditioning systems where each zone is controlled by a physical duct damper. The zone status reflects the damper state, independent of whether the HVAC plant is currently running.

Refer the below table for the controls:

Controls	Description
Plant ON/OFF (Read only)	This parameter represents the HVAC plant ON/OFF status. This value is shown as read‑only in the Zone Control widget and reflects the current plant status. The Zone Control operates irrespective of plant ON/OFF status.
ZONE STATUS (OPEN/CLOSE/CLIMATE)	Select the zone control (OPEN/CLOSE/CLIMATE). OPEN: The zone damper is open. Air flows into the zone when the plant is running. Zone Controls (Open/Close/Climate, Airflow, and Setpoint) are active, and any changes made are applied immediately. CLOSE: The zone damper is closed. Airflow to the zone is stopped, but allows you to make changes. However, these changes are saved temporarily and will be applied when the zone is turned ON. CLIMATE: The zone damper is managed automatically by the HVAC system based on climate conditions. NOTE: For a self-managed zone (where climate status is available in the tag map object), if you change the zone status from CLOSE to OPEN in the Manager UI, the changes are applied temporarily. After a short duration, certain HVAC system will automatically send a command to reset the zone status back to CLIMATE mode, and the Manager UI will update the status accordingly.
AIRFLOW	Displays and allows adjustment of the airflow level (0 – 100 %) for the zone. Value is mapped from the C-Bus airflow object. If the zone is closed, changes are pre-staged and applied later. Airflow not shown if no airflow object is configured. Tap / to increase/decrease the airflow percentage.
Current temperature (Read only)	Displays the current temperature of the zone. Available only if a temperature sensor object is configured. Used for real-time monitoring.
Zone Humidity (Read only)	Displays the current humidity level. Available only if a humidity sensor object is configured. Provides environmental status of the zone.
SETPOINT	Allows you to view and adjust the target temperature for the zone (if configured). Displayed only when a setpoint object and temperature sensor are configured. Any value outside the allowed range is automatically restricted to defined limits. NOTE: The setpoint object supports temperature values in the range of 10 °C to 40 °C. When you set a valid temperature (for example, 30 °C), certain HVAC system accepts the value and updates the setpoint accordingly. If you attempt to set a temperature outside the supported range (for example, 50 °C), certain HVAC system rejects the value and automatically reverts the setpoint to the last valid temperature. This helps to maintain only supported temperature values are applied within certain HVAC system. Tap / to increase/decrease the set point temperature. NOTE: If an object is missing/not configured, that corresponding control will not be displayed or will be disabled.
