Siemens RWI65.02 - Controller Operation

Siemens Building Technologies CM2N3204E / 05.2001
Landis & Staefa Division 9/20
The controller consists of a controller insert and the 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 loosened.
An EEPROM stores all setting values. In the event of a power failure, the setting values
are retained for an unlimited period of time. The reserve for weekly scheduling (typically
48 hours) is contained in the controller insert. As a result, the insert can be removed
from its base without affecting the actual time settings.
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.
The RWI65.02 is operated from four operating levels: information level, setting level,
scheduler program level, and commissioning level.
When the front door is closed, the display shows the following information:
Selection of operation (black pointer), manipulated variables, temperatures, weekday,
time, and status information.
The following settings can be made (if not disabled): operating mode (Automatic, fan
speed II, fan speed I, Standby), time of day, weekday, and daylight saving or standard
time (summer- or wintertime).
