Installation
The REHAU room unit is designed as an electronic temperature controller of
warm water heating systems and serves to control electrothermal actuators
or other electrical devices as appropiate. 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 certifi ed 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 furni-
ture or other objects. The control should not be installed close to heat sources
(i.e. lamps, fi replaces/chimneys, direct sunlight etc.) and positioned away from
draughts. Ensure that it is fi tted on a fl at, solid surface that is non-conductive
between 1.2 - 1.5m off the ground fl oor. This allows the room temperature to
be exactly measured and correspondingly precisely controlled.
Wall mounting
Before mounting the wall unit, take off 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 fi rmly mount the base plate on the wall or the fl ush-mounted socket with
the screws provided.

Temperature reduction
The unit comes factory supplied with all jumpers set to ON. You can change
the settings in accordance with your requirements, by moving the jumpers
onto contact pins as above, ensure that jumpers are fi tted i.e. in the correct
notation, and not removed.
Replace the cover in the reverse order to above.
Operation
The REHAU Star 30 Digital room controller is used for regulating the tem-
perature in dry, enclosed rooms with a normal environment and maximum
humidity of 95% (non condensing).
The desired temperature can be quickly and easily adjusted with the push
buttons. This electronic control system ensures that the set room tempera-
ture is maintained without fl uctuation and when required a time signal input
automatically activates a reduction in temperature (night setback).
Each time you press any button, the display’s illumination will automatically
switch on. If there is no adjustment made then after 5 seconds, the illumina-
tion will switch off again automatically.
Pressing the + or – buttons this will take you to the display of the desired
temperature setpoint. Here you can modify this temperature by pressing
the + or – button repeatedly, in steps of 0.5K, until you reach your desired
setpoint temperature.
Note:- It is not possible to set temperatures of below 10°C or above
35°C.
If there is no activity for more than 5 seconds, the controller will automati-
cally adopt the amended desired temperature and will revert to the standard
display.
If a timer is connected and temperature set back is active, this will be dis-
played by a
symbol in the display. If the controller calls for heat because
the actual temperature is below the desired temperature set,
this will be indicated by
symbol in the display.
