Need help?Do you have a question about the Gewa GL-4M WM and is the answer not in the manual?
GL-4M is a programmable IR receiver with four relay outputs. It can be programmed with GewaLink channels and one coded channel.
All connections are made by jacks, allowing connectors to be removed before wiring. Broken lines indicate internal production links.
The detector is the eye receiving the IR signal. Up to two external detectors can be connected. An internal detector can be disabled.
The receiver features four relays with alternating contacts. Maximum relay loading is specified in Technical Specifications.
The IR receiver and window opener require an 18V DC supply. Connect the enclosed power supply, noting the polarity.
The lid of the GL-4M model can be fixed using the screws provided with the unit.
Clean the outer casing of the receiver by wiping it with a damp rag with mild washing-up liquid.
