Standard version: With cross-counterflow heat exchanger, device as right-hand version, Highly efficient, intelligent central ventilation unit with heat recovery for comfort ventilation. , Compact and very quiet device for wall or floor mounting (optional). An easily accessible USB port for service/commissioning is a feature of all device variants. DC motors with , integrated, automatic volume flow control for a constant air volume (volume flow constancy). The DC motors can also be operated at a constant pressure using the optional additional board ZP 2. 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. Inner 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 Institute for Air Hygiene Berlin in accordance with VDI 6022 Part 1. Additional sound-absorbing lining in the supply air duct. Maximum airtightness. Filters can be easily changed without tools. 4 pipe connections DN 160. Can be fitted with various connectors or pipe bends (accessories). The device variants WR 310 and WR 410 can be upgraded at a later date (e.g. electrical PTC preheater (optional) or bypass (optional) or enthalpy heat exchanger (optional). DIBT approval. PH validation. Control unit RLS 1 WR: Included in delivery. Switching of the 4 ventilation levels, maintenance display, fault messages. Additional control units can be connected in parallel. Touchscreen 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 devices have an integrated web server and can be operated via APP from home or on the go, e.g. via smartphone. Live reports, user management, control and settings via WebTool, via tablet, laptop and PC. Settings: Demand-controlled Automatic mode / time-controlled automatic mode. Manual mode / OFF. ECO mode supply air or ECO mode extract air. Filter queries, error messages. Registration required. For more information, see www.air-home.de. Control: 3 temperature sensors in the outside, exhaust and supply air nozzles. 1 combination sensor (temperature and humidity) in the extract air nozzle. Integrated overhumidification prevention function. Continuous, demand-based adjustment of air volumes. Multifunctional contact for controlling the brine-earth heat exchanger EW (unregulated pump), operating and fault display, preheating or post-heating register, outside 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 unit into the EnOcean world www.enocean-alliance.org. KNX: Optional KNX plug-in module K-SM enables connection to the building management system, www.knx.org. Heat exchanger: Highly efficient cross-counterflow plate heat exchanger made of plastic (PS). Frost protection: Prevents the heat exchanger from freezing at low outside temperatures by switching off the supply air fan. Recommendation: Combine devices with 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 of 80...320 m3/h (WR 310) or 80...470 m3/h (WR 410), continuously adjustable. Installation instructions: Easy, very time-saving installation with the included mounting hardware.
