Safety and hazard information
Please note that electrotechnical work may only be carried out by qualified electricians or under their guidance and supervision. Observe any deviating country-specific electrical installation standards and regulations and seek advice from a local electrician.In addition, observe more current safety instructions and regulations for the products on the manufacturer's side or the product descriptions and installation instructions on the manufacturer's side.

Devices with a connected load of > 380V/400V require a heavy current connection and may only be connected by an approved electrical company. Devices with a power rating > 12kW require the approval of your grid operator (Germany, other countries may differ).

Room air system bypass up to 250 m2 - Central air supply and -exhaust device WS 320 B – Maico – 0095.0221 – 4012799952213: Room air system bypass up to 250 m2 WS 320 B, energy efficiency class=A+, energy efficiency class spectrum=A+ to G, type of ventilation=central supply and exhaust air, heat recovery via=cross counterflow, heat source=outside air, nominal power=37 W, degree of heat provision=96 %, rated current=1.5 A, with hot water preparation=no, with heating=no, with remote control=yes, air connection diameter=160 mm, height=857 mm, width=841 mm, depth=598 mm, weight=67 kg, volume flow =320 m³/h, Max. speed=2750 1/min, With water air heater=no, Bypass version: With bypass and cross-countercurrent heat exchanger, device as left-hand version, Highly efficient, intelligent central ventilation device with heat recovery for comfort ventilation. Compact and very quiet device for wall or stand mounting (optional). An easily accessible USB port for service/commissioning characterizes all device variants. DC motors with integrated, automatic volume flow control for constant air volume (constant volume flow). The DC motors can also be operated at constant pressure using the optional ZP 2 additional board. High level of customer service/user-friendliness thanks to modern device module technology. High flexibility thanks to various equipment and connection options. Housing: sheet steel, powder-coated. Color: white aluminum. Interior lining made of temperature-resistant and extremely sound- and heat-insulating plastic (EPP). The material is also characterized by its hygienic and non-hygroscopic properties. Tested by the Berlin Institute for Air Hygiene in accordance with VDI 6022 Part 1. Additional sound-absorbing lining in the supply air duct. Maximum airtightness. Filter changes are easy without tools. 4 pipe connections DN 160. Can be variably equipped with plug connectors or pipe bends (accessories). All device variants (e.g. K) can also be retrofitted into other device variants (e.g. KRET) using optional components. DIBT approval. PH certification. Control panel RLS 1 WR: Included in delivery. Switching of the 4 ventilation levels, maintenance display, fault messages. Additional control panels can be connected in parallel. Touchscreen control panel 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 devices have an integrated web server and can be operated via mobile app from home or on the go, e.g. via smartphone. Live reports, user management, control and settings via web tool, tablet, laptop and PC. Settings: Demand-controlled automatic operation / Time-controlled automatic operation. Manual operation / OFF. ECO mode supply air or ECO mode extract air. Filter queries, error messages. Registration required. For further information see Control: 3 temperature sensors in the outside exhaust and supply air connections. 1 combination sensor (temperature and humidity) in the exhaust air connection. Integrated over-humidification prevention function. Continuous, demand-driven adjustment of air volumes. Multifunctional contact for control of brine-earth heat exchanger EW (uncontrolled pump), operating and fault display, preheating or postheating register, external flaps. Can be expanded with additional boards (e.g. ZP 1, ZP 2). Modbus: Integrated MODBUS interface enables integration into the building management system. Enocean: Optional EnOcean plug-in module E-SM for integrating the ventilation device into the EnOcean world KNX: Optional KNX plug-in module K-SM enables connection to the building management system, heat exchanger: Highly efficient cross-countercurrent plate heat exchanger made of plastic (PS), or . on the ET device variants, washable antimicrobial enthalpy heat exchanger made of plastic (PS). Frost protection: Prevents the heat exchanger from freezing at low outside temperatures. For K device versions, there is an integrated demand-controlled electrical PTC preheater. For non-K device versions, by switching off the supply air fan. Recommendation: For non-K device versions, combine heat recovery with a brine-earth heat exchanger. Energy-efficient fans: 2 radial direct current fans, curved forward in the supply air or exhaust air. 4 ventilation levels from 80 to 320 m3/h continuously adjustable. Installation instructions: Easy, very time-saving installation with the wall bracket included in delivery. Housing cover can be easily removed using practical magnetic fasteners. Provide silencers on the supply and exhaust air sides. Electrical connection: Ready for use with on/off switch. Prepared for easy-to-install connection of sensors. Expandable functional electronics compartment allows easy installation of optional additional boards (ZP 1 and ZP 2). Condensate drain: Condensate drain (1 1/2 strainer valve). Connection to an optional siphon (DN40). Easily cleanable condensate tray integrated in the EPP housing.
