6.7 Supply air and extract air silencers
Supply air and extract air silencers reduce the noise from RoofVent
®
units within
the room. The supply air silencer is designed as a separated component and
is installed above the Air-Injector. The extract air silencer consists of acoustic
insulation lining in the connection module.

6.8 Condensate drain inside
The neutralised condensate from the gas condensing boiler can be channelled
inside the RoofVent
®
unit to the drain connection in the connection module.
To prevent icing of the condensate, the condensate line is heated.
6.9 Energy monitoring
Energy monitoring makes it possible to display the energy saved by heat recovery.
For this purpose, 2 additional temperature sensors are installed in the RoofVent
®
units; they record the air inlet and air outlet temperatures of the plate heat
exchanger.
6.10 Return temperature sensor
The return temperature sensor monitors the return temperature of the heating
medium.
Notice
RoofVent
®
KG units are equipped with a return temperature sensor in the
gas boiler attachment as standard.
