6.7 Features of the COMPLETE control solution
Al functions of the COMPACT version are included in this version.
Below are listed only the additional features of the COMPLETE control solution.
6.7.1 Post-Ventilation
By setting the parameter PG05=1 it is possible to decide whether to run the fans for a time
configured on parameter PF11, also after unit switch-OFF. If the function is active when the unit
stops the fans keep working for further PF11 seconds.
6.7.2 Differential pressure switch
The lack of air flow is signalled via the DI6 Differential Pressure switch digital input. The pressure
switch status is considered after the initial start-up phase of the unit (the length of this phase is
configured by parameter PA06). On expiry of this time if the contact signals a lack of air flow the
alarm is signalled immediately. During normal working the differential pressure switch is
monitored continuously. If the contact signals a lack of flow for a period exceeding the PA06
parameter, the alarm is signalled immediately.
To enable the alarm, set PA05=1.
The differential pressure switch alarm has manual reset. Activation leads to switch-off of the unit
taking it into the OFF due to alarm status.
