Options for connecting to unit control (electronics compartment)

Various components can be connected to the unit control (main circuit board in the electronics compartment), e.g. the RLS G1 WS touch operating unit. RS 485 connection options for sensors (HY, CO2, VOC) and an external operating unit are available. A digital switching contact allows various external components to be switched → Wiring diagrams.

• RLS G1 WS touch operating unit
  Standard installation with 2 magnets and bracket on the housing cover. Connection with 2-part RLS G1 WS connection cable (included in scope of delivery for WS 75 APA/UPA/UPGA). External installation on flush-mounted electrical box, connection with LIYCY 4 x 0.34 mm² cables. Recess in design/glass cover then has to sealed with optional RLS G1 V sealing kit.
