Supply air function for exhaust air fan

Here, the volumetric flow compensation for additional exhaust air fans can be activated at the 230 V input of the RLS 45 K. The function must also be enabled in the Specialist installer basic settings menu.
Parameter RLS 45 K function 230 VAC input = supply air function and/or parameter PPB 30 K push-button function = exhaust air mode.

If there are PP 45 devices in the system, the volumetric flow compensation always takes place via the PP 45 devices.

The supply air function of the PP 45 devices cannot be deactivated. BUT, if the "Disbalance" parameter is set to "activated", the RV 2 devices would also switch to supply air. Therefore, always leave the "Disbalance" parameter set to "deactivated" when PP 45 devices are connected.

If there are no PP 45 devices in the system, the volumetric flow compensation always takes place via the RV 2 and/or CPP 60 devices. In this case, the RV supply air function must be switched on with the activated button. For CPP 60 devices, the function must be activated in the CPP devices menu.
