Installation instructions
Safety information
This device constitutes, in conjunction with the corresponding radio temperature controller
, a control unit. This is why the rst installation of the device is to be made by an expert
electrician in due consideration of the currently applicable safety regulations and rules.
Caution! The operation of the radio room temperature sensor in the vicinity of other
devices that do not comply with the EMC directives may affect its functions. Settings
or changes of the adjustments made while operating in craftsman mode may affect the
control system and may therefore only be made by an accordingly qualied expert. 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.
7. Advice to the installer
A description of the following functions can be learned from the operating instructions
established for the radio temperature controller:
Central control (control of the heating/cooling operations performed in individual
rooms based on a central set value)
Average value control (acquisition of the temperature values sensed by several radio
room temperature sensors)
Master-slave control (automatic multiple room operation piloted by one central
clock-equipped controller)
Radio link loss (interruption of the radio link)
Emergency operation function in the case of a radio link loss (control if an interruption
of the radio link occurs)
Functional check of the radio link
8. Application
This radio room temperature sensor with time time-controller and energy economizing
function has been specially devised for the acquisition of temperatures in living spaces,
ofces and hotel rooms. It has been designed for the operation in association with one or
several radio-temperature controllers. The overall system that usually consists of both a
radio room temperature sensor and a radio temperature controller serves for the control of
temperatures that exist in different rooms. It is chiey used in the building reconstruction
sphere or wherever heating systems are to be extended and where the avoidance of
expensive cutting up and/or plaster works for the laying of electric cables is of importance.
The same applies also with regard to modern ofce complexes where exibility with regard
to the interior design is in the fore. 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 application,
please refer to section 18. herein (Warranty).
9. Functional description
The sensor measures, based on the data delivered to it by internal sensor, the actually
prevailing room temperature and transmits it, along with the desired set temperature, to
the correctly learned or assigned radio temperature controller. The system provides the
option to assign the radio temperature sensor to an arbitrary number of radio temperature
controllers. Several electric heaters / plate-type electric heaters or hot water valves can
thus all be triggered by one sensor only. The transmission range of the radio temperature
sensor depends largely on the prevailing spatial conditions. Sheathed or reinforced walls,
ceilings or metal casings will thus reduce the transmission range.
10. First start-up and commissioning
The radio room temperature sensor is not operable in condition as delivered. Readiness
for operation is obtained only through the insertion of the batteries and the assigning of the
radio temperature sensor to the related radio temperature controller by way of a so-called
„learning procedure“, see also section 11. hereafter, “Learning function”. When inserting
the batteries, care must be taken to comply with their correct polarity. The maximum
battery service life can be reached only when using batteries of the specied type and
quality. This device has been equipped with an additional backlight that requires a third
battery for supply. This battery is to be inserted centrically between the two batteries for
the supply of the temperature control operations. The lifetimes of the two batteries needed
for the supply of the temperature control operations and of the one needed for backlighting
are thus independent of each other. Once the batteries have been inserted, the room
temperature controller performs a self-test rst that lasts only some seconds. During this
self-test, all display symbols appear on the display. Once the self-test is over, the software
version used with the device is being displayed for some seconds.
10.1 Adaptation of the display and entry options to the controlled temperature
equalization system: heating system / heating & cooling (climate
conditioning) system / cooling system
The adjustment step J.11 is to adapt the radio room temperatur sensor to the controlled
temperature equalization system, i.e. to “heating only” (factory setting), “cooling only” or
“heating & cooling” (climate conditioning). This adaptation is required in order to activate
the display and entry options associated with the controlled temperature equlization sys-
tem or to deactivate all inapplicable ones (dynamic menu). Caution: If failing to adapt the
sensor to the temperature equalization system to be controlled, the energy economizing
function (ECO) will not be exectued once the operating modes “heating” or “cooling” have
not been activated.
11. Learning function
The learning function enables to assign and attune a certain radio temperature sensor to
the related radio temperature controller. There are two options to trigger the learning pro-
cedure to be performed by the radio room temperature sensor, scilicet either directly after
the insertion of the batteries during the commissioning as described in above section 10 or
while operating in adjustment mode (see section 3.1).
Learning procedure after insertion of the batteries: After the insertion of the batteries,
the execution of the self-test and the indication of the software version used with the de-
vice, an “L” is being displayed for 2 minutes to indicate that the device operates in learning
mode now. The radio temperature controller is, after the expiry of this time, changed over
to learning mode operation. Once this is the case the actuating this key triggers the
transmission of a learn identier for 10 seconds. Once this is over, the sensor changes over
and asks for the entry of the clock time.
1.) Change the sensor over to learning mode operation and actuate the lean key at the
radio temperature controller once shortly The lamp at the radio temperature controller
ashes red for max. 30 seconds. If no sensor is assigned by way of a learning procedure
within this time, the lamp stops ashing and changes back to its initial state.
2.) Press the key at the sensor once shortly The lamp at the radio temperature
controller ashes red for approx. 10 seconds. Once this time is over, the lamp at the
radio temperature controller stops ashing red and lights green permanently. The radio
link has been established successfully.
Once the learning procedure was performed correctly, the pilot lamp on the radio tempera-
ture controller shows green for approx. 1 hour. The control system is active now. Regarding
all other indications on the radio temperature controller, please refer to the section “lumi-
nous indications” contained in the operating instructions generated for this device. After
placing the radio temperature controller in the room to be controlled, the radio link must be
rechecked again for correct functioning. To ensure this, the pilot lamp on the radio tempe-
rature controller should be checked again if it shows green for approx. 1 hour as described
hereinbefore. In the event the required radio link is interrupted, the lamp shows red after
approx. 5 minutes. The green lamp extinguishes 1 hour after the successful execution of
the learning procedure and indicates thus that the system operates correctly.
12. Adjustment functions J.7 ... J.12 “craftsman mode” J.6 then and
Caution! Control settings can be made within the limits of these adjustment functions
that may only be performed by a qualied heating specialist or an expert electrician. The
settings made while operating in this mode cannot be reset via the reset function and have
to be made knowingly, therefore. Clear proof that any such settings have been made by
one person only is thus ensured. The activation of the craftsman mode takes place while
operating within the normal adjustment mode (see section 3.).
This is enabled only if „J.6“ is being indicated on the display. After that, press the key
rst and then the key shortly: the rst adjustment function available in crafts-
man mode (J.7) is being displayed now. After activation of the craftsman mode, all 12
adjustment functions can be selected by means of the and keys. Actuating the
key enables to cancel the craftsman mode at any time. If no such selection has been
made, the craftsman mode is terminated all automatically 2 minutes after the last keys-
troke was made. Entries will be imported only after conrmation with the key . After
termination of the program entry function, the display changes again back to the previously
indicated operating display.
12.1 J.7 Temperature unit °C or °F
The system enables to display the temperatures in the units Celsius or Fahrenheit
(factory setting: °C).
After that, the radio temperature
sensor changes all automatically over to
learning mode operation for a two minutes
time. The letter “L” appears on the display
during this time. Once the learning or
assigning procedure is over (see section
11.), the elds for the entry of the clock
time and the date appear blinking on the
display (“00.00”) and the operator is asked
to enter these data. Actuating the key
at this stage enables to stop the learning or
assigning procedure and to change to the
entry of the clock time and the date. If, upon
rst start-up and commissioning, no clock
time and date are entered, the automatic
mode is activated after the expiry of 2
minutes. Caution: If no clock time and date
are entered, the clock time starts running as
of 00.00 o’clock and the comfort heating
times are not consistent with the actual time
of the day. Section 2.1, “Entry of programs”,
contains a description of the setting of the
clock time and of the date after the activation
of the automatic mode.
Take care of the correct
polarity when inserting the
batteries!
