Safety information
No persons other than expert electricians only must open this device in due compli-
ance with the wiring diagram shown in the housing cover / on the housing / repre-
sented in the corresponding operating instructions.
Caution! The operation of the controller in the vicinity of other devices that do not
comply with the EMC directives may affect its functions. The company charged with
the installation of the device must, after the completion of the installation works,
instruct the user of the control system into its functions and in how to operate it
correctly.
These operating instructions must be kept at a place that can be accessed freely by
the operating and/or servicing personnel in charge.
1. Application
This controller has been specially devised for the control of electrical or hot water
heating systems / addition tiled stove heating systems, as well as for the control of
other surface temperature equalization systems. Regarding other applications not to
be foreseen by the manufacturer of this device, the safety standards concerning
these applications need to be followed and adhered to. Regarding the aptitude of the
device for any such other application, please refer to section 10. herein (Warranty).
2. Functional description
The controller measures, based on the data delivered to it by a special sensor instal-
led in the tiled stove the existing temperature with a switching difference of approx.
1K. The control operations of the device result in a surface temperature that is mainly
determined by the structure and composition of the tiled stove. With electric heating
systems care must be taken to ensure that the performance of the controlled system,
even if the system is operated continuously, do not result in an overheating of the
related surface structure. Caution! With surface structures that are designed as
sitting furniture or that provide special storing surfaces, care must be taken to ensure
that the actually adjusted temperature can neither cause nor lead to health hazards or
induce the inflammation of objects. To delimit the admissible temperature range, the
setting range can be restricted mechanically by means of a special facility that exists
underneath of the adjusting knob (see section 8).
The HTRRB-011.410 is equipped with an ON/OFF switch that enables to activate or
deactivate its control operations. The red lamp that has been provided for this purpose
indicates the active state of the heating system. The heating system is deactivated in
the event of a sensor breakdown or sensor short-circuit and also in the event the
sensor measures a temperature below -5°C (which is equivalent to a sensor break-
down).
3. Installation
The device is, depending on the type version of the device or size of the package
used for it, either delivered in closed or, in order to facilitate its fast installation, also
in opened condition. Caution! The controller must not be installed on a conductive
surface. This applies in particular when metalliferous wallpapers or wall claddings of
a similar nature have been used. After its installation on the wall surface or on an UP
box and after completion of its electrical connection, the housing cover is hooked up
using the upper hooks and then swivelled down until it snaps in. The electrical
connection of the device must be realised as illustrated in section 9 herein. The
sensor carries line voltage potential and may only be extended by means of a double-
insulated cable (type H05SS-F, for example). The double insulation required by
EN 60730 -1 needs to be observed at the connection point too. Care must be taken to
ensure that the sensor line is not laid in parallel to line voltage carrying cables or
lines. Where parallel laying cannot be avoided, a shielded line must be used and the
shielding be connected to terminal 6. In order to ensure the easy replacement of a
defective sensor, the sensor including its line needs to be laid inside an empty con-
duit in a replaceable manner. The protecting sleeve, type THF, serves for the closing
of the empty conduit that has been concealed in the related surface structure (see
section 6., Accessories). The sensor must, in order to obtain an optimal distribution
of the heat in the surface structure, be positioned centrically between two heating
conductors. With warm-water heated surfaces, normally closed valves are to be used.
Possibly required temperature limiters need to be installed in addition.
