Operation Mode.
To change the Operation Mode from the Home Screen, press the Operation Mode icon and select the desired operation mode:
Cool. In this mode, the conditioning unit will start a cooling cycle any time that any zone is in cool demand (TSet-Point < T room).
Heat. Enables the heating cycle whenever a zone is in heating demand (TSet-Point > T room).
Auto. The Auto mode allows automatic switching between cool and heat, depending on the global demand.
Dry. Only available in direct expansion systems. The system works in dry mode, refreshing the zone (reducing the humidity)
when any of the zones is generating demand (TSet-Point < T room).
Note: Dry mode decreases humidity in the room by entering the dehumidification cooling cycle.
Emergency Heat. This mode activates the Auxiliary Heat to provide heated air in case of a mechanical failure in the system.
Note: This mode is only visible when the installation includes an auxiliary heating device.
User Mode
To change the User Mode from the Home Screen, press the User Mode icon and select the desired mode:
Comfort. Default and standard user mode. The desired set point temperature can be selected using the predefined
temperature ranges.
Eco. The range of available set point temperatures change for more efficient operation.
Night time. The system automatically changes the set point temperature 0.5 C/1 F every 30 minutes in up to 4 increments
of 2 C/4 F in 2 hours. When cooling, the system increases the set point temperature; when heating, the system decreases
the set point temperature.
Unoccupied. To be used when there is no presence detected for short periods of time. A more efficient set point
temperature will be set. If the thermostat is activated, the zone will start running in comfort mode.
Vacation. This mode feature saves energy while the user is away for extended periods of time.
Stop. The air-conditioning system will remain switched off regardless of the demand status of any zone, all the motorized
dampers will remain opened.
Airflow
Select the control algorithm that best fits the installation. The available options are:
Silence. The fan speed is lower than in standard mode to reduce the noise.
Standard. Default setting. The system automatically regulates the fan speed based on the number of zones calling for
cooling or heating.
Power. The fan speed is higher than in standard mode to increase the flow.
Local Ventilation
This option enables the activation or deactivation of the ventilation in the selected zone when the system is not actively
cooling or heating any of the zones.
