Air Conditioning (AC) Unit Control

Air-conditioning (AC) Unit Control widget provides quick access to the below AC parameters:

Power status
Operation mode
Fan speed
Temperature setpoint

You can turn the AC plant ON or OFF, select the desired operation mode, adjust the fan speed, and configure the target temperature (setpoint). The widget also displays the current temperature and humidity reading, that allows you to monitor the environment in real time.

NOTE: The controls and information displayed in the widget depend on the C-Bus objects mapped during configuration. If a parameter is not configured in Configurator, the corresponding control or information will not be available in the Manager interface.

To operate the AC Unit Control:

Click power button to turn on/off the widget.

Off State

On State

When the plant is ON, all AC controls such as MODE, FAN SPEED, and TEMPERATURE become active.
When the plant is OFF, you can still configure MODE, FAN SPEED, and TEMPERATURE (pre-staging). The Air Conditioner will start with these configured settings when the plant is turned ON.

Select to access the temperature.
Click / to increase/decrease the set temperature.

You can set the desired temperature that the AC unit should maintain. The updated temperature value is displayed on the screen.

NOTE: Temperature setpoint can be adjusted only when the mode is set to COOL, HEAT, DRY, or AUTO. It cannot be adjusted when the mode is set to VENT, EXHAUST, PUMP, or any other custom mode.
Select to access the fan speed.
Click / to increase/decrease the fan speed.

You can adjust the fan speed level supported by the AC unit. The updated fan speed is displayed on the screen.

The fan speed options displayed depend on the supported levels reported by the connected HVAC system and configured in the fan speed object. The Manager interface reads the fan speed object and displays the available levels exactly as defined in the configuration. Common fan speed levels include:
- LOW
- MEDIUM
- HIGH
- AUTO
- BOOST
- QUIET
- TURBO
NOTE: Fan speed can be adjusted only when the mode is set to COOL, HEAT, DRY, AUTO, or VENT. It cannot be adjusted when the mode is set to EXHAUST, PUMP, or any other custom mode.

Description

Current temperature (Read Only)

Displays the real-time temperature reading from the configured temperature sensor.

Plant Humidity (Read Only)

Displays the value for monitoring the ambient humidity level in the conditioned space.

Plant Humidity is used to:

Provide environmental information along with temperature readings.
Support HVAC monitoring or automation scenarios if humidity control is required.

Example: You can use the AC Unit Control widget to remotely manage your Air Conditioner. Turn it on and set your preferred temperature before you arrive home, so you walk into a cool and comfortable room.
