The signal reported at the controller corresponds to the room temperature changed using the
rotary knob. The following signals are forwarded to the controller according to the switch set-
ting:
Automatic mode
= Room tempe/- inverse rotary knob
Normal mode
= Room tempe 50°C +/- inverse rotary knob
Lowering mode
= Room tempe 100°C +/- inverse rotary knob
Standby mode
= Room tempe 150°C +/- inverse rotary knob
The increased values for normal, lowering or standby mode are evaluated internally in the
heating circuit controller function module of the UVR16x2, UVR1611 and UVR63-H control-
lers. The display in the measured values overview of the UVR1611 and UVR16x2 takes
place without offset values of the operating mode switch.
Use as a remote control
If the installation location of the room sensor is unsuitable as a reference room, the room
sensor
RAS-PLUS
can also be used merely as a
remote control
, in that
Index 5
is used as
the measured value. In this way a fixed value of 20°C with offset values of the +/- setting and
the slider switch are forwarded to the controller.
Room sensors with other controllers
In the controllers ESR31 (from version 1.0), ESR21, UVR61-3, UVR63 (from version 5.0) and
UVR63-H (version 5.0 up to 7.1), only the measured room temperature can be evaluated, i.e.
without offset values (index 2); the slider switch and the rotary knob have no purpose with
these controllers.
Key operation for the display values is as for the controller UVR1611.
Installation
The sensor can only be used in dry rooms and can be installed directly on a level surface or
in a standard device enclosure.
The room sensor must be opened for mounting. A small screwdriver is used to press in both
the clamps beneath the temperature selection knob and slider switch while simultaneously
raising the cover. The base plate can now be easily mounted.
Electrical connections
The sensor has to be connected to data link (DL-bus) and sensor mass. The connection po-
larity is unimportant.
Any cable with a cross section of 0.75 mm² can be used for the data link (e.g. twin-strand)
having a max. length of 30 m. For longer cables, we recommend the use of shielded cable.
