Operating the unit

ER-UP/Centro units are usually switched on and off manually (using a switch), depending on unit model and connection variant.

Barrier-free units work as per the automatic function. Alternatively, these units can be operated using an optional switch.

Please read the relevant sections in these instructions (ER-UP controls (circuit board types)) or contact your installer or planner for details of the special functions and operating characteristics.
