Siemens AEROGYR RWI65.01 - Mechanical Design and User Interface; Display and Operating Elements; Operation Modes

CM2N3205E / 05.2001 Siemens Building Technologies
8/18 Landis & Staefa Division
The controller consists of controller insert and base.
The controller insert accommodates all operating elements and the electronic circuits. It
is secured to the base by two screws which are designed such that they push the insert
away from the base when they are loosened.
The microprocessor with the memory, the associated electronic components, and the
display are carried by one printed circuit board, the relays by another. Another board
serves for communication and carries a specific microprocessor with the associated
interface. An EEPROM stores all setting values. In the event of a power failure, the
setting values are thus retained for an almost unlimited period of time. The reserve for
the weekly time switch (48 hours typically) is contained in the controller insert. For this
reason, the insert can be removed without having an effect on the actual time setting.
The base is made of plastic and is designed for both wall and flush panel mounting. In
the case of flush panel mounting, the controller is secured by a clamp. The base carries
four terminal blocks and a terminal strip for establishing the electrical connections with
the controller insert.
