Centralised ventilation unit WS 320 BET
Features
Highly efficient, intelligent, centralised ventilation unit with heat recovery for comfort
ventilation.
Compact and very quiet unit for wall / standalone mounting (optional).
An easily accessible USB port for service/start-up characterises all unit variants.
DC motors with integrated, automatic volumetric flow regulation for constant air volume
("volumetric flow consistency").
The DC motors can be operated via the optional additional "pressure constant" PCB ZP 2.
Good customer service/ease of use thanks to modern unit module technology.
Good flexibility thanks to various equipment and connection options.
Housing: Sheet steel, powder coated.
Colour: white aluminium.
Inner cladding made from temperature-resistant and extremely noise- and heat-insulating
plastic (EPP). The material is also characterised by its hygienic and non-hygroscopic
properties. Tested by the Institut für Lufthygiene Berlin [Berlin Institute for Air Hygiene]
according to VDI 6022 Part 1.
Additional noise-insulating cladding in the supply air guide.
Maximum air tightness.
Simple filter change is possible without tools.
4 DN 160 duct connections.
Can be equipped with plug-in connectors or duct bend (accessories).
All unit variants (e.g. "K") can also be converted into other unit variants (e.g. "KET") later on
using optional components.
DIBT approval.
PH certification.
RLS 1 WR control unit
Included in the scope of delivery.
Switching the 4 ventilation levels, maintenance display, fault messages.
Other control units can be connected in parallel.
Touch screen control unit RLS T1 WS
Optional.
Up to 6 operating modes possible.
2 automatic operating modes (Auto Sensor / Auto Time).
4 manual operating modes (ECO exhaust air / ECO supply air / MANUAL / OFF).
air@home
The units have an integrated web server.
Can be controlled with an app when at home or out and about, e.g. using a smartphone.
Live reports, user administration, control and setting using web tool. Via tablet, laptop and
PC.
Needs-based automatic mode / Time-controlled automatic mode.
Manual operation / OFF.
ECO mode supply air or ECO mode exhaust air.
Filter queries, error messages.
Registration needed. For more info, see www.air-home.de.
Controller
3 temperature sensors in outside, outgoing and supply air connections.
1 combination sensor (temperature and humidity) in exhaust air connection.
Integrated excess humidity avoidance function.
Continuously variable needs-based adaptation of air volumes.
Multi-function contact for controlling EW brine earth heat exchanger (uncontrolled pump),
operating and fault display, preheating and postheating register, shutters.
Can be extended with other PCBs.
ModBus
Integrated MODBUS interface enables integration in the building control technology.
EnOcean
Optional EnOcean plug-in module for integrating the ventilation unit into "EnOcean world"
www.enocean-alliance.org.
KNX
Optional KNX plug-in module allows for connection to building control technology,
www.knx.org.
Heat exchanger
Highly efficient cross-counterflow plate heat exchanger made of plastic material (PS),
and/or washable, anti-microbial enthalpy heat exchanger made of plastic (PS).
Frost protection
Prevents the heat exchanger from freezing up at low temperatures.
For "K" unit models, using integrated, demand-controlled, electrical PTC preheating
register.
For "non-K" unit models, by switching off the supply air fan.
Recommendation: Combine "non-K" unit models with heat recovery with a brine earth heat
exchanger.
Energy-efficient fans
2 centrifugal DC fans, curved to the front. In the supply or outgoing air.
4 ventilation levels between 80.. 320 m³/h can be adjusted continuously.
Mounting instructions
Easy, very time-saving mounting with the wall bracket included in the scope of delivery.
Housing cover is easy to remove using practical magnetic locks.
Provide sound absorbers on the inlet and outlet sides.
Electrical connection
Ready for service with on/off switch.
Prepared for assembly-friendly connection of sensors.
Extendible, functional electronics box allows optional additional circuit boards (ZP 1 and ZP
2) to be fitted with ease.
Condensation drain
Condensation drain (1 1/2" screen valve).
Connection to an optional siphon (DN40).
Easy-clean condensate tank integrated in EPP housing.
