2�5 Emergency operation/Fire mode
If the potential-free switch contact DI2 is closed, the unit will switch to emergency operation/fire mode.
Access to the settings: Log on as Admin.
The emergency operation/fire mode settings can be found in the "Configuration" menu - "Fire protection":
• Operation during alarm (stopped, only supply air fan, only extract air fan, normal operation, continuous operation)
• Speed during fire alarm Supply air, Extract air
Fan stage during fire alarm ↑
SAF: 11 %
EAF: 7 %
Operat. when alarm stopped ↓
• Pressure Supply air/Extract air during fire alarm (-1 means no change to previous operation)
Pressure SAF/EAF
during fire alarm
SAF: -1 Pa
EAF: -1 Pa
A pre-set fan speed can be set for use in the event of a fire. This function is deactivated with "-1". The fire mode is
activated by closing the switch contact DI2.
