6.10.9 Fan status
Below are the different operating modes in which each fan may find itself:
1. Disabled: the fan has not been configured for the plant. In this status in the user interface you will see the
symbol “-“.
2. Off: the fan is off. In the user interface you will see written “ON” when in this state “OFF”.
3. On: the fan is on. In the user interface you will see written “ON” when in this state “ON”.
4. Waiting for Start-up: the fan is about to Start-up, and is in a temporary queue. In this status in the user
interface you will see written (and flashing) “WON”.
5. Alarm: the fan is in alarm for thermal reasons or because of the alarm inverter. In the user interface you will
see written “ALARM” when in this state.
6. Manual: the fan is operating manually. In this status in the user interface you will see written “MANU”.
A fan operating manually is nevertheless sensitive to eventual alarms; in this case the status will be that of Alarm.

Thermal fan alarms or inverter alarms can be connected to the controller. Per fan there is one digital input available.
6.10.11 Environment temperature robe in error mode
In case of a room temperature sensor failure, it is possible to define a predefined fan speed by parameter PF10.
In case where the fans are On/Off controlled, the parameter PF10 must be set to a value greater than 0.0% in order to
keep the fans in operation.
If PF10=0.0%, the two fans are off.
