Supply air mode for exhaust air fans with run-on time

Run-on time 0, 6 or 15 minutes

The RLS 45 K controls the CPP 60 ventilation units and exhaust air fans connected to the 230 V input (ECA 100 ipro, ER 60).

If the switch-on of an exhaust air fan is detected, all PushPull ventilation units connected to the respective RLS 45 K (CPP 60, RV 2, PP 45 and PPB 30) switch to supply air mode. A volumetric flow compensation takes place to compensate for the resulting negative pressure.

The volumetric flow compensation is set to a total of 60 m³/h for exhaust air units.

For correct operation, the correct number of units must be stored in the service menu.

Only use exhaust air units with an exhaust air volumetric flow of 60 m³/h, e.g. ER or ECA 100 pro. When an exhaust air fan starts up, the PushPull units go into supply air mode to compensate for the negative pressure produced.

Once the set run-on time has elapsed, the ventilation units switch back to the previously selected ventilation level.

Sensor-controlled exhaust air units with automatic start-up are not recognised by the RLS 45 K.
