High flexibility thanks to various connection options. Housing made of sheet steel, powder-coated. Colour: white aluminium. Inner lining made of temperature-resistant and extremely sound and heat-insulating plastic (EPP). The material is also characterised by its hygienic and non-hygroscopic properties. Tested by the Institute for Air Hygiene Berlin in accordance with VDI 6022 Part 1. The slim device is also particularly suitable for installation in kitchens. Filters can be changed easily without tools. 4 pipe connections DN 125. Can be fitted with connectors or pipe bends (accessories). Connection to KNX possible. Connection to EnOcean possible (WS 170KBR../WS 170 KBL..). Integrated MODBUS interface (WS 170KBR../WS 170 KBL..). DIBT approval (except WS 170..ET). PH validation (except for WS 170R../WS 170 L.. and all WS 170..ET). Control unit RLS 1 WR Included with all WS 170 devices. Switching of the 4 ventilation levels, maintenance display, Fault messages. Optional with/without on/off switch. Additional control units can be connected in parallel. Digital control unit RLS D1 WR Optional for WS 170 R.., WS 170 L.., WS170 KR.. and WS 170 KL... Control and power supply via 2-core bus cable. Digital status display, switching of the 4 ventilation levels, date and time (weekly program, plus function, maintenance display and fault messages). Plus function (summer mode): In eco mode only the exhaust fan runs, thus saving approx. 50 P power. Touchscreen control unit RLS T1 WS Optional for WS 170 KBR../WS 170 KBL... Up to 6 operating modes possible. 2 automatic operating modes (auto sensor / auto time). 4 manual operating modes (ECO exhaust air / ECO supply air / OFF). air@home The devices WS 170 KBR../WS 170 KBL.. have an integrated web server and can be operated via mobile app from home or on the go, e.g. via smartphone.
