Bypass version: With bypass and cross-current heat exchanger. Device as a right-hand execution. High-efficiency ventilation device reaches energy efficiency class A + without optional accessories. Modulating, automatic 100% bypass for passive summer night cooling with adjustable minimum supply-call temperature limit. Short description: Central compact very quiet apartment ventilation unit with heat recovery. For controlled ventilation and ventilation. Especially suitable for modern new construction and renovation. KfW eligibility and NRW support are available. Assembly wall-hanging, or standing (optional). ISO Coarse 85% (G4) filters in the exhaust air and ISO ePM1 80% (F7) pollen filters in the outside air. A filter cascade (ISO Coarse 85% / ISO ePM1 80%) in the outdoor air is possible to increase the filter time. All devices are equipped with state-of-the-art cross-counter-current heat exchangers, or enthalpian heat exchangers with health certificates according to VDI 6022, sheet 1. Complete separation of the exhaust air / supply system throughout the device. This prevents unwanted air circulation. Viruses (e.g. Corona virus) and bacteria are not transmitted. Room air control RLS 1 WR in delivery. All apartment ventilation devices can be controlled by APP (air @ home) and the browser-based web tool (www.air-home.de) using an integrated LAN interface. Standard USB connection for commissioning, control update and service. All devices are equipped with high-energy fans in EC technology. The integrated / automatic volume flow control ensures a permanent compliance of the set volume flow under all operating conditions (e.g. filter pollution, air venting settings). This also results in a simpler start-up / air measurement on the valves. A standard integrated combis sensor (humidity / temperature) in the exhaust air allows a demand-led ventilation operation as well as an intelligent frost protection and dehumidification strategy (overmoisture protection). All devices are characterised by a freezing strategy adapted to the real needs. In addition, all devices have a multi-function contact for the control of e.g. sole- earth heat exchangers (unregulated pump), operating and fault display, preheating or post-heating registers, external valves or cooling. 2 input contacts (12 V and 230 V) are available for e.g. safety-related shutdown. Various inputs / outputs allow for a control connection to other home-technology devices, e.g. heat pump. Integrated MODbus interface (TCP / IP and RTU) for integration into the building management technology. The optional K-SM plug module allows integration into the KNX building systems. The E-SM optional plug module allows integration into EnOcean systems. Optional additional panels ZP 1 and ZP 2 for extension functions such as pressure control of the EC fans, zone flap, solar heat exchanger (controlled pump), filter differential pressure measurement. Maximum device flexibility through various equipment / connection options. Modern device module technology allows easy retrofitting (e.g. preheating, bypass) as well as high user-friendliness for service and maintenance. Housing: powder-coated steel sheet housing. Color: traffic white, similar to RAL 9016. Filter change possible without tools. Density heat-free inner housing made of temperature-resistant, sound and heat-reducing EPP material (average wall thickness 47 mm). EPP housing with very good hygienic / non-hygroscopic properties. Material tested by the Institute for Air Hygiene according to VDI 6022. Condensate pan integrated in the EPP housing. The device surface and interior housing are easy to clean. Sonic interior lining in the supply channel. Condensate flow via sieve valve 1. Optional device siphone DN 40 (see accessories). Filter: ISO Coarse 85% (G4) filter in the exhaust air and ISO ePM1 80% (F7) pollen filter in the outside air. Optional filter cascade (ISO Coarse 85% / ISO ePM1 80%) in the outdoor air possible to increase the filter time. Tool-free filter exchange. Operation: Ready to use with on / off switch. Control part RLS 1 WR in delivery, 4 air levels, filter change indicator, fault indicator. Further control parts can be connected in parallel. Mobile operation using APP (air @ home) or browser-based web tool (www.air-home.de) via smartphone, laptop or PC allows for example live message, user management, demand-driven automatic / time-controlled automatic operation, manual operation / OFF, ECO- operation supply air, filter queries, error messages, optional touch-screen control RLS T2 WS for the setting of 2 automatic mode of operation (car / time), input-up of the ECOS, complete power-to-power-power-to-power-power-to-power-power-to-power-power-power-to-power-power-to-power-power-to-power-to-power-power-power-to-power-power-to-power-power-power-to-power-to-power-to-power-to-power-power-to-power-to-power-to-power-power-to-power-to-power-to-power-to-power-to-power-to-power-power-to-power-to-power-to-power-to-power-to-power-to-power-to-power-to-power Network connection via integrated LAN interface. Smart-Home ready (e.g. Loxone via Modbus TCP / IP). Modbus TCP / IP and RTU integrated as standard. Optional KNX plug module K-SM for integration in the building management technology www.knx.org. Optional EnOcean plug module E-SM for device integration into the EnOcean world www.enocean-alliace.org. Control: Serial required flow control (relevant moisture value). Continuous adjustment of air volumes. Integrated overmoisture protection function. 3 temperature sensors in the external, forward and supply air. 1 combis sensor (temperature and humidity) in the exhaust air. Up to 4 external sensors of different types (CO2, VOC, humidity) can be connected. Multi-function contact for the control of e.g. sole- earth heat exchanger (unregulated pump), operating and fault display, preheating or post-heating register, external flap or cooling. Inputs for safety-related shutdown over 12 V contact or 230 V contact (e.g. smoke detectors, fire alarm, differential pressure-free fire site). Additional key input for triggering time-limited intensive ventilation (shock ventilation). Extensible via optional additional board ZP 1 for the control of: 3-way flap (e.g. air-earth-heat exchangers), a controlled pump (e.g. solar-earth-heat exchanger), an air flap of a zone control, switching contact use for external post-heating register, extendable via optional additional board ZP 2 for: pressure constant of the EC fans, differential pressure-controlled filter monitoring, various inputs and outputs allow a control connection of the ventilation unit with a different heat pump, e.g. a heat-like device.
