INSTALLATION
OVERVIEW
Installation
The REHAU room unit is designed as an electronic temperature con-
troller of warm water heating systems and serves to control electro-
thermal actuators or other electrical devices.
The maximum switching current indicated in the technical data
must be observed! REHAU cannot accept any liability for any form of
misuse.
The electrical installation must be carried out in accordance to the
current wiring regulations in force and must be in accordance with the
connection plan. Only approved certified professionals may carry out
the installation. Further more the installation is always to be carried
out with the power supply disconnected.
Position the room unit such that it is not covered by curtains, pieces of
furniture or other objects. The control should not be installed close
to heat sources (i.e. lamps, fireplaces/chimneys, direct sunlight etc.)
and positioned away from draughts. Ensure that it is fitted on a flat,
solid surface that is non-conductive between 1.2-1.5m o the ground
floor. This allows the room temperature to be measured at the correct
height and results in more comfortable control.
Wall mounting
Before mounting the wall unit, take-o the housing cover from the
base plate.
1. Remove the screw on the underside
2. Open the housing by lifting the housing cover on the bottom edge
and then lifting it.
Now firmly mount the base plate on the wall or the flush-mounted
socket with the screws provided.
Ensure batteries are positioned in corrext polarity and are
secure in the base plate

Replace the cover in the reverse order to above.
Operation
The electronic REHAU Star 50 room unit, controls the temperature in
dry closed rooms with normal environment and a maximum relative
room humidity of 95% (non-condensing).
The desired room temperature can be set very easily with + or - to
increase or decrease temperature Set Point. The REHAU Star 50
ensures stable room control by maintaining the set point room tem-
perature.
The REHAU Star 50 becomes the master controller and sends the
set back signal to all other Star controllers connected to the common
wiring centre.
