230 V input: Additional functions
When connecting the 230 V input (switching contact) of the RLS 45 K, one of the following additional functions can be selected:
- Time-limited intensive ventilation (intermittent ventilation)
- Time-limited switch-off (sleep function)
- External safety function OFF
- Supply air mode for exhaust air fans, run-on time 0, 6 or 15 minutes
The function must also be activated in the service menu or with the commissioning software.
When the additional functions are switched on, the 
symbol flashes on the control unit.
Ventilation units on other RLS 45 K continue to run with the previous operating mode and ventilation level.
Exception: With the External OFF safety function, all ventilation units in the ventilation system switch off. When the External OFF safety function is triggered, the symbol display flashes slowly.
The RLS 45 K enables communication between exhaust air fans (ECA 100 ipro, ER 60) and the PushPull units. When an exhaust air fan starts up, the PushPull units switch to supply air mode to compensate for the negative pressure produced.
